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
Maria (1836 ship) Maria (1836 ship) The barque Maria was launched at Yarmouth in 1836. "Maria" was originally used on the England to Bombay run in the 1830s. She sank with the loss of 28 lives on 23 July 1851 near Cape Terawhiti on the North Island of New Zealand. Only two crew members survived. "Maria" was a barque built at Yarmouth in 1836 and originally owned by J Somes to 1838, then Gardiner and Co. Her masters were Humble to 1838, Black to 1839, Johnstone to 1845, and Stevenson in 1846. In 1839, 1844 and 1947 she was sheathed with yellow metal.
