Rudolf Christian Böttger (28 April 1806 – 29 April 1881) was a German inorganic chemist. He conducted most of his research at the University of Frankfurt am Main.He is credited with discovery of nitrocellulose in 1846, independently to Schönbein, and with the synthesis of the first organocopper compound copper(I) acetylide Cu 2 C 2 in 1859.
Nitrocellulose film on a light box, showing deterioration, from Library and Archives Canada collection. In 1855, the first human-made plastic, nitrocellulose (branded Parkesine, patented in 1862), was created by Alexander Parkes from cellulose treated with nitric acid and a solvent.
Christian Hackenberger grew up in Damme.He attended the Gymnasium Damme, where he obtained his Abitur in 1995. After completing his civil service, he studied chemistry at the Alfred-Ludwig-Universität in Freiberg (1996–1998) and the University of Wisconsin-Madison (M.S. with Samuel H. Gellman, 1998–1999), with support from the German Academic Scholarship Foundation. [4]
German-Swiss chemist Christian Friedrich Schönbein created the explosive substance nitrocellulose, or "guncotton", in 1846 by treating cotton fibers with a nitric acid and sulfuric acid mixture. However, guncotton proved to be too fast burning for direct use in firearms and artillery ammunition.
August Wilhelm von Hofmann (8 April 1818 – 5 May 1892 [2]) was a German chemist who made considerable contributions to organic chemistry. His research on aniline helped lay the basis of the aniline-dye industry, and his research on coal tar laid the groundwork for his student Charles Mansfield's practical methods for extracting benzene and toluene and converting them into nitro compounds and ...
