Knallgold und Knallsilber

Curt Wentrup

Abstract: Dieser Essay beschreibt die faszinierenden und hochexplosiven Verbindungen Knallgold und Knallsilber,d ie leichtmittels Behandlung von in Kçnigswasser gelçstem Gold mit Ammoniak bzw.d urch Reaktion von Silberoxid oder Silbersalzen mit Ammoniak hergestellt werden kçnnen. Insbesondere Knallgold hat im 16. bis 18. Jahrhundert die Alchemisten gefesselt. Zahlreiche Herstellungen wurden beschrieben, und viele Versuche wurden unternommen, destillierbares, sublimierbares oder trinkbares Gold zu erzeugen und die so erh… Show more

17 th century chemistry was concerned largely with iatrochemistry (medicinal chemistry) and the transmutation of metals, especially with the purpose of making gold. Thus, Johann Rudolph Glauber made a living making and selling chemicals such as nitric acid and medicaments such as aurum potabile (drinkable gold), but he also believed in the transmutation or "improvement" of metals and the "augmentation" of gold, and he sold recipes for such processes. This perspective aims to provide a snapshot of the range of 17 th century chemistry by analysis of the efforts of four representatives to make drugs, chemicals, and gold. It will be concluded that early modern chemists were unable to break out from the conceptual doctrines imposed by Aristotle and Paracelsus, which made transmutation perfectly logical. No further scientific advance could be made until the idea that all things are composed of the same basic constituents was abandoned in favour of the atomic theory.

The words organic and synthesis originate with Aristotle (meaning 'instrumental' and 'put together', respectively) but had different meanings over time. The iatrochemists prepared numerous pharmaceutical remedies in the 1600s but had no concept of organic chemistry. Buffon, Bergman and Gren defined organic bodies as living things in the 1700s, but discrete organic compounds remained unknown. In the late 1700s and early 1800s, organic natural products were isolated by Scheele, and Chevreuil separated carboxylic acids from saponification of fats. Organic chemistry had started. Lavoisier invented and Berzelius improved combustion analysis for organic characterization. Descartes' dictum that synthesis is required to prove an analysis was enacted by Bergman and others. The concept of organic chemistry changed radically when Wöhler and Kolbe prepared organic compounds from the elements. Berthelot's syntheses of non-natural fats in 1853 started modern synthetic organic chemistry as the chemistry of carbon compounds, regardless of whether occurring in Nature or not.
