3 Foreword The immediate reason to start working on a chemical-historical lexicon of inorganic substances was a discussion of lexicographical and terminological problems for the recording of specialist terms at the Herzog August-Bibliothek Wolfenbüttel in the summer chemical dissertation from 1817 to translate the names in use today. Once again I was painfully aware of the lack of relevant reference works or databases. What were the same substances called in the 19th, 18th and 16th centuries? What about synonyms? What to think of aliases? In this context, it is also important to clarify the following questions: Who was the first to produce and characterize which substance? Who gave what name? Who was the first to set up a formula or set the structure? While it is relatively easy to obtain chemical historical information about the few more than 100 elements of the periodic table, it becomes difficult and arduous with the millions of compounds. The situation is softened a little today by the fact that a relatively large number of publications from earlier centuries, which until a few years ago were difficult to access, were often banned on high bookshelves in the basement of libraries and are now accessible online and can be searched for keywords. A major problem in the history of chemistry, which cannot be elegantly solved, is that the possibilities to purify substances and also to measure this purity really only existed in the course of the 19th century. The further you go back, the more impure the substances used become, so that information (e.g. from the 16th century) about certain metal compounds often enough has nothing to do with the specified substance, but can only be ascribed to the accompanying substances contained therein (the impurities) . This caveat! is therefore always appropriate when it comes to historical fabric names. The selection of the keywords included in this data collection is more or less arbitrary. Attempts were made to take into account the materials used in the time of alchemy in the 16th century, but also not to forget important names of Arabic and even Alexandrian alchemy. A focus was placed on the late 17th and early 18th century. The following criteria were decisive for the later period: importance of the substance for industrial purposes, importance for scientific developments. Certain developments in metal complex chemistry and organometallic chemistry of the 19th and 20th centuries were also taken into account. This edition is the second version published on-line. Improved ones will follow in the coming months. The use of electronic search systems is recommended to quickly find the keywords. The appendix also serves this purpose.

5 UIPAC name Formula Actinium Ac Aluminum Al Old designations Notes The previously adopted statement that André Louis Debierne discovered actinium in 1899 while processing the pitchblende residues of the two Curies, was seriously questioned in 1971 by Harold W. Kirby. According to Kirby, it would have been Friedrich Oskar Giesel who in 1902 was the first to hold actinium-containing preparations. Giesel called the new element Emanium. Debierne's suggestion Actinium (from ακτίνος = ray) prevailed. Around 1909 it was Carl Auer von Welsbach who produced by far the purest actinium preparations that glow in the dark in his laboratory in Treibach. Humphry Davy tried unsuccessfully to make aluminum in 1808. (The element name is derived from the Latin word alumen for> alum.) The first representation of elemental aluminum - albeit in a rather impure form - was achieved in 1825 by Hans Christian Ørsted by converting> aluminum chloride with potassium amalgam. Friedrich Wöhler used pure potassium as a reducing agent in 1827 and thus obtained a much purer aluminum. Henri Étienne Sainte-Claire Deville used sodium as a reducing agent in 1846 (published in 1859). Sainte-Claire Deville and Robert W. Bunsen succeeded independently in the electrolytic production of aluminum from molten NaAlCl by Charles Martin Hall and Paul Héroult, the electrolysis process named after them Developed for the production of aluminum: the Hall-Héroult process, in which> aluminum oxide is mixed with cryolite and the melting point is lowered from 2045 C to approx. 950 C. From 1889 Carl Josef Bayer developed the Bayer process named after him for the production of pure aluminum. 5 Literature references primary / secondary F. O.

6 aluminum (I) chloride AlCl aluminum carbide Al 4C 3 aluminum chloride AlCl 3 aluminum nitride AlN nium oxide (from bauxite) as the starting product of the fused-salt electrolysis. AlCl was discovered in 1987 by J. Cernicharo, M. Guelin in interstellar matter. The salt was first produced in 1989 by M. Tacke and Hansgeorg Schnöckel. The aluminum carbide was first described by Henri Étienne Sainte-Claire Deville in 1855. In 1897, Henri Moissan melted alumina and calcium carbide together in an electric furnace to produce it. Joseph Franz von Jacquin reported in 1793 in the chapter On the other alum earthy middle salts that hydrochloric acid combined with pure alum earth (i.e. Al 2O 3) results in hydrochloric acid alum earth (Argilla salita, Murias aluminae), which is a mass that dissolves in the air; In 1810 he mentions the name Alumina muriatica. Johann Andreas Scherer explained in 1792 that the names murias aluminosus and sel marin argileux mean the same thing. Antoine Francois Fourcroy knew such a sel marin argileux as early as 1786. A production of anhydrous AlCl 3 from alumina and HCl gas was protected by a patent in 1891 by C. A. Faure. The existence of the aluminum nitrogen compound AlN is stated in 1862 by Friedrich Briegleb and Johann Georg Anton Geuther 6 J. Cernicharo, M.

At the beginning of the 20th century, AlN played an important role in connection with the Bayer nitride process patented by Ottokar Serpek for the production of pure Al 2O 3. In the 1980s, the importance of this good heat conductor for microelectronics was recognized. Stick gases to metals, Ann. Chem. Pharm. 123 (1862); J. W.

In 1817 Joseph Louis Gay-Lussac produced aluminum oxide from> ammonia alum by annealing, during which NH 3 and SO 2 escape. In 1845 Friedrich Wöhler published a process in which he obtained pure clay from alum and CaO. The process developed by Carl Bayer in 1889 is based on bauxite. The earliest mention of a Lemnian earth goes back to Theophrastus in the 3rd century BC. In the first century AD, Dioscurides reported that the Lemnian soil from the island of Lemnos came from a certain cave-like tunnel. The white clay was called bolus alba. The red bolus rubra contains hematite additions. In 1756, Axel Friedrich von Cronstedt named those aluminum silicates zeolites that seemed to boil when heated with a fan burner because of the open silicate structure. The preparation Mercurius praecipitatus albus, as it was produced in the 19th century, was not> calomel but amidomercury (II) chloride. 7 O. Serpek, Austria. Chem.

8 Ammonia NH 3 Gaseous ammonia was first mentioned in 1716 by Johannes Kunckel. The gas was first isolated in 1774 by Joseph Priestley as "alkaline air". Further research was carried out by Carl Wilhelm Scheele and Claude-Louis Berthollet, who recognized the composition of ammonia from nitrogen and hydrogen, and William Henry, who determined the exact ratio of the two elements of 1: 3 and thus the chemical formula NH 3. Joseph Franz von Jacquin gave in 1793 as the production method for the pure or caustic ammonia (Ammonia pura seu caustica) in the 4th edition of 1810, he already spoke of ammonia gas - the reaction of living lime (CaO) with the volatile alkali salt (NH 4) 2CO 3 at. In the coal gasification plants, NH 3 was obtained as a by-product in the coke oven gas. Fritz Rothe discovered the manufacturing process using the calcium cyanamide process. In April 1900 Wilhelm Ostwald registered a patent for the "production of ammonia and ammonia compounds from free nitrogen and hydrogen". However, there was no success. In the spring of 1903, the owners and managing directors of the Österreichische Chemische Werke, the brothers Otto and Robert Margulies, turned to Fritz Haber with the same question as to whether it would be a good idea to look for a way to produce ammonia from atmospheric nitrogen and hydrogen. When Haber succeeded in developing such a process after an initial failure in collaboration with Walter Nernst, Carl Bosch, Alwin Mittasch from BASF and others, he wanted to get in touch with the Margulies brothers, who had supported him. However, this was prevented by BASF. The characteristic blue coloration that occurs when alkali metals are dissolved in liquid ammonia was observed by W. Weyl (Humphry Davy saw a reaction of potassium with gaseous NH 3 as early as 8 Jacquin 1793, p. 156; Wilhelm Ostwald, Lebenslinien: Eine Selbstbiographie, Klasing & Co ., Berlin 1926/27, p. 283; W.

The name spiritus Mindereri was used for this until the 19th century. According to Ernst Friedrich Anthon (1833), the expression sal ammoniacus liquidus was also used for solid acetas ammoniae, probably because this salt is deliquescent. In 1800 at the latest it became common to leach out alum slate deposits with the help of rotten urine, which led to the formation of ammonium aluminum alum (ammonia alum), e.g. in 1802 in the Friedrich Wilhelm tunnel near Lichtenberg. Ammonium carbonate is a component of deer horn salt. (The main component of the stag's horn salt, however, is the ammonium hydrogen carbonate NH 4HCO 3.) Stag's horn salt also contains certain amounts of ammonium carbamate H 2NCONH 4, which has been obtained for centuries by dry distillation of rasped stag's horn (but also from claws, hooves, etc.) Andreas Libavius ​​used roasted deer horn salt in 1603 in connection with blood preparations.

10 was the first to describe representations of the volatile lye salt in 1684. A recipe with fixed Salammoniacum and Bodaschen (potash) by Matthäus Erbinäus von Brandau (an alchemist in the vicinity of Emperor Rudolf II in Prague around 1600) was printed in 1689. In the case of the spiritus urinae, which already occurs by Raymondus Lullius as Spiritus animalis (or Mercurius animalis) and which, e.g. Ulstadius or Libavius ​​write, was obtained by distillation of (bacterially decomposed) so-called putrefected or rotten urine, it was an aqueous solution of ammonia, ammonium carbonate, ammonium hydrogen carbonate and ammonium carbamate. The preparation of Spiritus salis armoniaci from salmiak and wood ash, in which there is a reaction K 2CO NH 4Cl = (NH 4) 2CO KCl, was described by Johann Hartmann in the early 17th century. In 1793, Siegismund Friedrich Hermbstädt described the production of a sal alcali volatile salis ammoniaci (volatile salmiac salt or aerated volatile alkali salt) from salmiac and potash by heating in a retort, whereby an obviously sublimable salt passes over and the digestive salt (i.e. KCl) remains. 2 NH 4Cl + K 2CO 3 -> (NH 4) 2CO KCl Joseph Franz von Jacquin (1810) differentiates the Alcali volatile (the carbonate ammonia, Ammonium carbonicum) from the Carbonas ammoniae alcalescens, the alkaline carbonate ammonia (Subcarbonas ammoniae), which is an the air becomes neutral.

11 Ammonium chloride Salmiak NH 4Cl Ammonium iron (II) sulfate Mohr's salt (NH 4) 2Fe (SO 4) 2.6 H 2O The sublimability of salmiac is already described in the writings of the Jabir Corpus. The oldest name that appears in the Arabic scripts is the Persian-Arabic name nusadir. In the translations of the text into Latin, the name sal ammoniacum is used, a name that actually refers to the salt of the ammonium oasis, but which can be chemically identified with table salt: Pliny speaks of Hammoniacus sal in his Nat. Hist. 31/39 in connection with a fossil salt near the temple of Jupiter Ammon in what is now Libya. (This makes it clear that the name ammonia or ammonium ultimately comes from the ancient Egyptian god of wind and fertility, Amon, and from the 11th dynasty onwards it was mixed with the Re cult of Amun-Re.) Liber de inventionis veritatis, which counts the corpus, is reported about the sublimation of sal ammoniac, but also about its production from urine, sweat, rock salt and soot. In 1546 Georg Agricola mentions a natural occurrence of sal ammoniac in the Dead Sea. Angelus Sala produced salmiac from hydrochloric acid and volatile alkali in 1620. In 1810, Jacquin reported about salmiac, which he also called hydrochloric ammonia, sal ammoniacus, Murias ammoniae and Ammonium muriaticum, that it was found in chimneys in Egypt as the product of camel manure burned. This iron (II) salt, which is relatively stable in the air, was named after Karl Friedrich Mohr, who made great contributions to the development of titration in the middle of the 19th century. It was also Mohr who suggested this salt for adjusting potassium permanganate solutions for oxidimetry.

12 Ammonium fluoride NH 4F (NH 4) 2PtCl 6 NH 4HSO 4 Ammonium hexacyanoplatinate (IV) Ammonium hydrogen sulfate Ammonium magnesium phosphate NH 4MgPO 4 As Johann Christian Wiegleb discovered as early as 1781, hydrofluoric acid ammonia (Fluas ammoniae, Ammonium fluoricum) attacks glass. In 1813, Humphry Davy observed the formation of white crystals during the action of HF on NH 3. The so-called platinum almiac was produced in 1881 by Karl Seubert and further investigated in 1910 by Ebenezer Henry Archibald. Only in the 4th edition of his textbook from 1810 does Joseph Franz von Jacquin mention the semi-decomposed salt called acidic sulfuric acid ammonia (Sulfas acidulus ammoniae), which forms diamond-shaped crystals and dissolves in the air. The triple salt found in urine was precisely described by Antoine François de Fourcroy and his colleague Vauquelin in 1803 under the French name phosphat ammoniaco-magnésien, after both authors had published references to the occurrence of this salt in 1799 and 1799 respectively. In his Latin dissertation on urine from 1817, Ami Boué spoke of the sal triplex phosphatum ammoniaco magnesianum. Georg Ludwig Ulex found the corresponding mineral struvite in 1846 during excavations under the Church of St. Nikolai in Hamburg. 12 RÖMPPS 1979, vol. 1, p. 188; J. Ch. Wiegleb, Crells new.

The ammonium nitrate is said to have been described by Rudolph Glauber as nitrum flammans as early as 1659. Caspar Neuman also studied nitrum flammans (1732), as did Rudolph Augustin Vogel (1762). In 1810, Joseph Franz von Jacquin also referred to ammonium nitrate as Flaming Saltpeter. Synonyms are: ammoniacal saltpeter, nitric almia (Nitrum flammans, Nitrum ammoniacale, Nitras ammoniae and Ammonium nitricum). G. S. Serulla first produced ammonium perchlorate in the early 1830s. Ammonium persulfate is the easiest persulfate to produce. It was obtained in 1893 from K. Elbs by electrolysis of a solution of ammonium sulfate in sulfuric acid. According to Friedrich Ludwig Meissner (1833), the spiritus sulfuris volatilis, which Jean Beguin produced in 1608 by distilling sulfur, unslaked lime and ammonium salt, was hydrothionic acid ammonia and, according to Wolfgang Müller, ammonium polysulphide.

Around 1800, Antoine François de Fourcroy and Louis-Nicolas Vauquelin identified ammonium phosphate as one of the salts found in urine. Joseph Franz von Jacquin mentions Glauber's secret salmiac among sulfuric acid ammonia (Sulfas ammoniae, Ammonium sulfuricum) in the 3rd edition of his textbook (1803). Johann Christian P. Erxleben reported on the sal ammoniacus secretus Glauberi as early as 1784. Georg Christian Lichtenberg said (around 1788): Sal ammoniacus secretus Glauberi. What kind of names are these. They don't make you smarter. Yes, on the contrary, as soon as one becomes wiser, one sees that they are useless and that they have to be thrown away. In 1783 Nicolaus Jacquin emphasized the great volatility of this salt. Also only in the 4th edition of his textbook from 1810 does Joseph Franz von Jacquin list the sulphurous ammonia (Sulfis ammoniae, Ammonium sulfurosum).

15 Antimony Sb Antimony (III) chloride SbCl 3 Antimony (III) oxide Sb 2O 3 Marcellin Berthelot reported in 1887 that he was analyzing a fragment of a vase (this was then in the Louvre and came from an excavation Ernest de Sarzec near Tello (h) in Chaldea in what is now southern Iraq) found pure antimony (99%). The artifact belongs to the Uruk period, which today dates from 3800 to 3000 BC. Is dated. According to Peter Moorey, it is very likely that native antimony was used as the starting material (the melting point of pure Sb is around C). In any case, the high purity, which was verified in 1975, is astonishing. Vannoccio Biringuccio reports on a regulus antimonii and its use as an alloy component of letter metal in his Pirotechnia by Ètienne-François Geoffroy added the Regule d Antimoine to the list of metals in his affinity table in 1718. Lavoisier added metallic antimony to his list of elements in 1789 under the name antimoine. Paracelsus was the first to produce fairly pure antimony oil (oleum antimonii) from antimonite and HgCl 2. Oswald Croll Leonhard Thurneysser merged Sb 2S 3, NH 4Cl and KNO 3 in 1570. The residues in retort A29 in the Oberstockstall complex indicate that the Thurneysser method was used here. The antimony oil that can be distilled off at C (or the antimony butter, butyrum antimonii, which has solidified below 73 ° C.) was generally converted to mercurius vitae (> antimony oxychloride). At the turn of the 17th to the 18th century, the terms hydrochloric spitglaz or Murias stibii were in use. The antimony oxides Sb 2O 3 and Sb 2O 4 were already known in the 14th century.

(SbOCl is initially formed, which turns into Sb 4O 5Cl 2, the latter being to be understood as 2 SbOCl. Sb 2O 3.) The name Algarot (t) powder goes back to the Veronese doctor Vittorio Algarotti (), who was influenced by Paracelsus. In the 19th century the preparation was called Stibium chloratum basicum, but eventually became obsolete. Antimony (III) sulfide was used in Egypt from the 3rd millennium BC. Chr. As dark make-up. The stibnite (antimonite, gray spit gloss) was called الكحل (al-kuhl = the coloring) in the Arabic language area. Almost all authors of the 16th or early 17th century (e.g. Thurneysser or Libavius) mean the mineral antimonite when they speak of antimonium or stibium. Already in a vocabulary of the 12th century one finds a vitrum antimonii, i.e. the spit-gloss glass, which is created when the spit-gloss is heated and which is a mixture of mainly Sb 2O 3 and about% Sb 2S 3. The pharmaceutical antimony preparation of the 18th century, which was made from antimony butter and nitric acid and called Bezoardicum minerale, mainly contained antimony tetroxide. In the 17th century, antimonium diaphoreticum (perspiration-inducing lime) was obtained by deflagrating gray spit gloss with excess saltpeter, which was a valued medicinal product and is made from antimony (V) oxide and potassium antimonate KSbO 3 p. 277; Schröder p. 100ff .; Paracelsus 3, 150 Schröder, p. 93ff.

The official name was stibium oxidum fuscum, when William Ramsay and John William Strutt, 3rd Baron Rayleigh, announced the discovery of a new element they named argon (from the Greek ἀργός = inert). Until 1957, the element symbol for argon was A. The name reveals a lot: The Latin arsenicum goes from the Greek to the Persian az-zarnikh, which denotes the yellow> auripigment (zar = gold). Geber latinus mentioned metallic arsenic in the Liber fornacum. (Pseudo) -Albertus Magnus described the production of arsenic by reducing arsenic with soap. Aristotle is probably referring to this striking mineral in his Historia animalium when he writes about a poison called Sandarak. The name Realgar comes from the Arabic رهج الغار, rahǧ al-ġār and means something like cave powder. Both the alchemists of late antiquity and those of the Arab era appreciate realgar and> auripigment. In 1556 Georg Agricola listed both the realgar and the auripigment as gold-bearing minerals. In 1597 Libavius ​​used the name realgaria.

The beginning of the smelter production in the important mining area Rotgülden in Lungau took place around the middle of the 14th century. Synonyms: arsenicum album, arsenicum sublimatum; Paracelsus tried to reduce the toxicity of arsenic preparations by oxidizing them with saltpeter, which resulted in potassium arsenate. The yellow mineral auripigment was already known to the Aristotle student Theophrast under the name Arsenikon. The term sulfur without fire used by Stephanos of Alexandria in the 7th century seems to refer to auripigment. Georg Agricola described the operment Arsenopyrite occurs on the Mitterberg near Mühlbach am Hochkönig in Salzburg, where mining has been documented since the early Bronze Age. To what extent the arsenic content of the early bronze artifacts, all of which are arsenic bronzes, can be traced back to the arsenopyrite present there is an open question. Arsenopyrite was found among the minerals and ores found in the Oberstockstall laboratory from the late 16th century. In 1775, Carl Wilhelm Scheele produced arsenic acid in two ways: by dissolving arsenic acid (H 3AsO 3, which can be obtained by dissolving> arsenic in water) in chlorine water, or by directing chlorine gas into a solution of arsenic acid.

The first pure presentation was made in 1855 by melting electrolytic by Robert Bunsen and Augustus Matthiessen. Carbonic or mild barite (Carbonas barytae, Baryta carbonica, Terra ponderosa aerata) was the name given to barium carbonate by Jacquin in 1810. Joseph Franz von Jacquin also uses the names murias barytae and barytae muriatica for the salty barite.

In 1810, Joseph Franz von Jacquin spoke of a pure barium or heavy earth (baryta, terra ponderosa), which is not found in pure form in nature. Jacquin obtained BaO by annealing nitric acid or carbonate of barium. The name alludes to the high density of naturally occurring barium minerals: Greek βαρύς = heavy.

Joseph Franz von Jacquin mentions in connection with sulfur baryte (Sulfuretum barytae) the bononic phosphorus, which has the property of attracting light and shining in the dark. Jacquin also differentiates from sulphurized barite a hydrogenated sulphurous barite (barium hydrogen sulphide Ba (HS) 2) which is formed when it is dissolved in water. This hydrogenated sulfur barite develops H 2S with acids. Azurite has been known for more than 4,500 years. The Egyptians of the Old Kingdom already used the powdered mineral for wall paintings. Azurite was also found in the color pigments of the wall paintings of the Maya of Bonampak. With the Greeks the mineral was known as ὰρμένιον and with the Romans Latinized as armenium or Armenian stone. This is where the term lapis armenicus (Armenia stone) can be found in some 18th century encyclopedias. The terms mountain blue, copper blue and copper glaze come from mining. The word azur is derived from the Latin word azzurum الژورد (blue), which in turn derives from the Persian lāžward = sky blue. During an excavation in Beidha near the Dead Sea, the earliest use of malachite as a green pigment could be proven 9000 years ago. The alpine mining of the carbonatic copper ore occurring in the oxidation zone can be traced back to the Copper Age. Malachite was used by the Etruscans for soldering in goldsmith's work.

The name is derived from the Latin molochitis from the Greek word μαλάχη, in ancient Greek maláchē for mallow (because of the green color of the leaves). Malachite was still used for soldering in goldsmith's work in the Middle Ages. Georg Agricola assessed the occurrence of malachite in 1556 as a good sign of ore exploration. Paracelsus was the first to describe the production of the bright yellow turbith in his hospital book in 1529. Michael Toxites mentions Turbith minerale in his Onomasticon II in 1574 as a sweet precipitat made on corosif. In the house pharmacy of Emperor Rudolf II there was a Turbit minerale, which B. Balduinus had made in Prague in 1603. The mining of the beryl variety emerald can be traced back to the 13th century BC in Egypt. Trace back to BC. For the etymology see> Beryllium. The etymology of the word emerald is derived either from the Semitic loan word אזמרגד (izmargad) or from the Sanskrit word मरकत (marakata). Both words mean green. Louis-Nicolas Vauquelin discovered a previously unknown earth that was initially named Glycine in an analysis of beryls and emeralds suggested by René Just Haüy. Martin Heinrich Klaproth preferred the name beryllium. In 1828 Friedrich Wöhler and Antoine Bussy independently reduced beryllium chloride BeCl 2 with the help of potassium to metallic beryllium, Paul Marie Alfred Lebeau produced pure beryllium by means of a melt-flow electrolysis of sodium fluoroberyllate Na 2 (BeF 2).

A method for the production of beryllium oxide given by C. F. Joy in 1864 goes back to Jöns Jacob Berzelius. Bis (benzene) chrome was first produced in 1955 by Ernst Otto Fischer and Walter Hafner. Franz Hein had already produced and published compounds such as [Cr (C 6H 5-C 6H 5) 2] + in the 1920s and 1930s, but did not recognize them as sandwich compounds. Suggestions for the sandwich structure of these compounds came from Harold Zeiss and Minoru Tsutsui around 1954. The contribution made in this regard by Lars Onsager in 1954 should also be taken into account. In a later statement, Franz Hein said that he had originally thought of sandwich structures; Such a hypothesis would not have been accepted at the time.

In 1772 Ignaz von Born listed this mineral as plumbum spatosum flavorubrum pellucidum. Von Wulfen dedicated his own monograph to him. The suggestion for the name Wulfenit goes back to Wilhelm von Haidinger (1841). The black lead (silver smoothness) that occurs during the driving process of so-called silver ores was called aphroselenon (foamed silver) by Zosimos of Panapolis, and either burnt lead or spuma argentis by Pliny. Another name is lithargyrum. Both red lithargite (-PbO) and yellow massicot (-PbO) were found in the remains of Roman wall frescoes. With regard to the lead colors used in painting from the 15th to the 17th century, Richard Jacobi was able to prove that these are usually> lead tin yellow and not - as originally assumed - massicot. In Johann Kunckel's Ars vitraria from 1679 there are references to the use of Bley ash or Glett for the production of pottery glazes.

Nikoljukin succeeded in lead tetrachloride to be brought into a weighable form as a double salt. Lead tetrachloride was finally produced in 1889 (or 1893) by H. Friedrich in Graz. It is said that the formation of lead superoxide (lead peroxide), which is known as platnertite e.g. occurs in Scotland, having been observed as early as 1780, it was examined more closely by Louis Nicolas Vauquelin. An early mention of a peroxide de plomb can also be found in Thomson's Systéme de Chimie 1818. As part of his book Leçons de chimie appliquée à la teinture, Michel Eugène Chevreul was the first to deal in detail with the peroxide de plomb, i.e. the brown PbO 2, in 1829. Chevreul determined the sum formula and gave information about the production from> red lead Wilhelm Josef Sinsteden developed the first lead accumulator based on a lead (IV) oxide coating on one of the lead plates. (Studies on the electromotive behavior of lead superoxide had already been published by PS Munck af Rosenschöld in 1835.) August Breithaupt first reported in 1837 on a mineral, heavy lead ore, which Wilhelm Haidinger named after Karl Friedrich Plattner Plattnerit in 1845 and which was -PbO 2 turned out. -PbO 2 was only described as a mineral called scrutinyite in 1988, whereby a synthetically produced -PbO 2 has been known since 1941. It is a matter of dispute whether Dioscurides has already given a regulation for the production of lead acetate. Paracelsus spoke of a quinta essentia plumbi, but left no prescription.

Lead azide was first presented by Theodor Curtius in 1891. It was patented by Lothar Wöhler in 1907 as the initiator. Lead (II) chromate was discovered by Louis-Nicolas Vauquelin in Paris. The possibility of using this chromate as a color pigment was recognized by Vauquelin and Claude Louis Berthollet in 1804 (Parisian yellow or chrome yellow). From 1818 this problematic pigment (darkening due to the reduction of Cr (IV) to Cr (III) and toxicity) was actually used as a painter's paint. Vincent Van Gogh used chrome yellow almost excessively. Silver-bearing galena was the starting material for silver extraction in the ancient Laurion mine as early as the 3rd millennium BC. The Latin name Galena for the mineral galena goes back to Pliny the Elder. Ä. back. The name gloss for this lead ore has been documented since the 16th century. Abraham Gottlob Werner coined the term lead gloss in the late 18th century. In 1810, Joseph Franz von Jacquin called an artificial Bley gloss as sulphurized Bley or Galena plumbi arificialis or sulfuretum plumbi. Cerussa was already known in ancient times. The white pigment is mentioned by Theophrastus in the 4th century BC. BC, by Pliny Secundus and Dioscurides in the 1st century. It was made from lead through the action of air and vinegar (steaming).

In painting, until it was replaced by Naples yellow in the 18th century, type II lead-tin yellow was the standard pigment for yellow. In his report to the Kgl. Academy d. Science, the doctor and chemist Theodor Baron expressed himself in 1748 that borax and boric acid must be based on a previously unknown substance. Joseph Louis Gay-Lussac and Louis Jacques Thénard established elemental boron by reducing boron trioxide with potassium. Independently of this, and a little later, Sir Humphry Davy produced boron by electrolysis of boric acid, and Jöns Jakob Berzelius recognized the elementary character of the substance. One of the components of boracite, first described in 1787 by Georg Sigismund Otto Lasius as cubic quartz crystals from Lüneburg and named by Abraham Gottlob Werner in 1789, was specified by Joseph Franz von Jacquin as boraxic acid talc earth (Boras magnesiae, Magnesia boriatica) i.e. magnesium borate. The boracite was also called the Lüneburg diamond. The first gaseous substance to be described as the hydride of boron was reported by Francis Jones and R. L. Taylor in 1881.

Alfred Stock, who was intensively involved in borane chemistry from 1912, showed that the gas produced when magnesium diboride reacts with hydrochloric acid is a mixture of B 4H 10 and B 6H 12. The B 6H 12 described by Stock later turned out to be a mixture of B 4H 10, B 5H 9 and B 6H 10. In 1933, Stock proposed a structure analogous to ethane for the gaseous hydrogen boride (diborane B 2H 6). H. Christopher Longuet-Higgins introduced the concept of the three-center two-electron bond in the 1940s, whereby it should be remembered that Walter Dilthey in Erlangen had already made such a proposal in 1921. DF Gaines and R. Schaeffer synthesized pure B 6H 12 . William N. Lipscom received the Nobel Prize in Chemistry in 1976 for his research into the stereochemical structure and the theoretical explanation of the bonding in boranes.

33 HBr Cadmium Cd Calcium Ca Calcium acetate Ca (CH 3COO) 2 Calcium carbide CaC 2 Brom was already observed by the discoverer of bromine Antoine Jérome Balard Balard also produced hydrogen bromide from phosphorus, potassium bromide, bromine and water. In 1886, Jean Servais Stas gave precise information on the production of a concentrated hydrobromic acid. Friedrich Stromeyer and Carl Samuel Hermann discovered cadmium in contaminated zinc carbonate independently of one another. Stromeyer was also able to get the corresponding metal. The name cadmium was used for zinc and zinc ores in the Middle Ages. It goes back to the Greek καδμεία, which names a mineral named after Κάδμος, the founder of Thebes, Humphry Davy succeeded in electrolytically obtaining metallic calcium on a platinum sheet as an anode and a platinum wire as a cathode from moistened quicklime with the help of mercury oxide. It is possible that the tinctura corallinorum of Paracelsus was already a calcium acetate solution (or a calcium chloride solution). Oswald Croll described the sal corallorum obtained with the help of vinegar in his Basilica Chymica. Humphry Davy probably already had CaC in his hands when, while attempting to electrolytically produce calcium, he found a melt of Ca and C which, together with water, develops a foul-smelling gas. Friedrich Wöhler described an electricity-free carbide representation in 1863; Wöhler fused a zinc-calcium alloy with coal. Thomas L.

Willson applied for a patent for his invention in 1892 and received US patent A on February 21. Henry Moissan spoke on December 12, 1892 at a meeting of the French Academy about the production of calcium carbide in the electric furnace at C. Moissan published his results in 1893 and Die The oldest evidence of the processing of lime by burning (which produces> calcium oxide), extinguishing (> calcium hydroxide) and setting come from the mountain temple of Göbekli Tepe in Anatolia; they are years old. The first to understand the processes involved in lime burning in 1754 was Joseph Black, who spoke of the resulting> carbon dioxide as fixed air. In 1769, Nicolaus Jacquin confirmed Black's results when Joseph Franz von Jacquin called the common limestone carbonic, mild or airy lime (Lapis calcareus, Carbonas calcis, Calcaria carbonica) in order to distinguish it from the caustic lime, which when it occurs in nature, Calx pura , or Calcaria pura, and living lime (Calx viva), if it was produced in the lime kiln. He also calls the slaked lime, which he characterizes as hydrated lime, Calx extincta. On the basis of his work carried out between 1811 and 1813, Friedrich Stromeyer identified not only calcite but also aragonite as a form of calcium carbonate. The name aragonite goes back to the chemically incorrect name given to arragonian apatite by Abraham Gottlob Werner in 1788. In the same year Heinrich Klaproth showed that the mineral does not contain phosphorus. Werner called the mineral Aragonian calcite, later aragonite.

Incidentally, as early as 1754 Joseph Torrubia had indicated the occurrence of the conspicuous crystals near Molina de Aragon on the Rio Gallo. William Pryce described as early as 1778 that all forms of calcite result from simple cleavage from the basic form of the rhombohedron. René-Just Haüy formulated the basic laws of crystallography in 1781, using the example of calcite. Erasmus Bartholin described the birefringence property of calcite (double spar) as early as 1669. In 1810, Joseph Franz von Jacquin described the production of hyperoxygenated hydrochloric acid lime (Murias hyperoxygenatus calcis) by introducing oxygenated hydrochloric acid gas (Cl 2) into milk of lime (Ca (OH) 2). Joseph Franz von Jacquin mentions the hydrochloric acid lime in 1810 under the name of Glauber's fixer salmiak (Sal ammoniacus fixus Glauberi, Calcaria muriatica, Murias calcis), thus reminding of the reaction product of the reaction of salmiak with living (CaO) or mild lime mentioned by Rudolph Glauber (Ca (OH) 2. He mentions that earlier CaCl 2 was called lime oil (Oleum calcis) that dissolved in the air. Calcium cyanamide was first prepared by Georg Meyer in 1878 when this glowed residues from the urea sulphide with powdered CaO.In the spring of 1898, Fritz Rothe succeeded in providing evidence that the action of pure nitrogen on carbides of the alkaline earths cyanamide NCN 2- is formed. Rothe tried to patent his discovery, but had to cede the invention to Adolphe Frank as a result of an employment contract, which resulted in several Frank Caro patents.

Georg Agricola first described fluorspar in 1530 in his Dialogue Bermannus. Heinrich Schwankhardt etched glass in 1670 with fluorspar and vitriol oil. In 1771, Carl Wilhelm Scheele recognized fluorspar as a compound of lime and a still unknown acid, which he produced as fluorosilicate gas. Friedrich Mohs discovered the fluorescence of fluorite that becomes visible in ultraviolet light. (George Gabriel Stokes named this phenomenon of fluorescence after the fluorite - in analogy to the opalescence of opal.) In 1891 Clemens Winkler observed the formation of calcium hydride for the first time when CaO and Mg powder were annealed in a hydrogen atmosphere. From the elements, the CaH 2 was first presented by Béla von Lengyel in 1895. In 1810 Joseph Franz von Jacquin called the mild lime dissolved in carbonated water as acidic carbonate of lime (Carbonas acidulus calcis). Jacquin reports that when sulphurized lime (CaS) is dissolved, hydrogenated sulphurized lime (Sulfuretum hydrogenatum calcis) is obtained. Slaked lime = Calx extincta = hydrated lime. The dissolution in water is the lime water (= Aqua calcis). The skin of CaCO 3 visible on the surface was called by Jacquin Kalkrahm (Cremor calcis). The chlorinated lime, which is a mixture of approx. 35% calcium hypochlorite, calcium chloride and calcium hydroxide, was first found in 1795 by Pal Kitaibel Chlorkalk G.

This is how Andreas Libavius ​​called both salts sal nitri in 1597. In 1612, Martin Ruland described the substance aphronitrum as a saltpeter that grows on the moors and rocks. In 1673/74 Christoph Adolf Balduin published the description of the fluorescence of the calcium nitrate residue after adding nitric acid to lime chalk and then evaporating it. Therefore, strictly speaking, the name Phosphorus Balduini is the first really tangible name for anhydrous calcium nitrate. The oraculum, published anonymously in 1755, only referred to the Moor or cellar nitrate as sal petrae, while potassium nitrate is listed under nitrum commune. Joseph Franz von Jacquin names 1810 as synonymous names for the calcium nitrum nitrum calcareum vel terrestre, Nitras calcis and Calcaria nitrica. He also mentions Balduin's phosphorus under the same heading. Caustic lime = living lime = Calx viva; If this occurs in nature, it is called Calx pura or Calcinaria pura. The cause of the exothermicity of lime slaking was one of the great mysteries of antiquity and early modern times: Seneca d. J., Vitruv as well as Julius Caesar Scaliger and Gerolamo Cardano in the 16th century. put forward various theories.
