Acetylene of 180°. Acetylene was discovered in 1836 by Edmund Davy, who identified it as a "new carburet of hydrogen". It was rediscovered in 1860 by French chemist Marcellin Berthelot, who coined the name "acétylène". Berthelot's empirical formula for acetylene (CH), as well as the alternative name "quadricarbure d'hydrogène" ("hydrogen quadricarbide"), were incorrect because chemists at that time used the wrong atomic mass for carbon (6 instead of 12). Berthelot was able to prepare this gas by passing vapours of organic compounds (methanol, ethanol, etc.) through a red-hot tube and collecting the effluent. He also found that acetylene was formed by
Charles Tomlinson (scientist) was elected to the Royal Society, and in 1874 he took a leading part in founding the Physical Society. As a scientist Tomlinson made valuable contributions to the knowledge of the surface tension of liquids. His last years were devoted to literature, and he held the Dante lectureship at University College 1878-1880. He authored over 50 books and 100 published papers and notes, among which were: Written with his wife Sarah Tomlinson: Charles Tomlinson (scientist) Charles Tomlinson (27 November 1808 in London – 15 February 1897) was a British scientist, member of the Royal Society, and author.
