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
1836 Grand Liverpool Steeplechase race was totally omitted and remained forgotten for over a century before being rediscovered early in the 21st Century. It is still regarded officially by Aintree as not being worthy of Grand National status and is instead regarded as the first of three unofficial precursors over the same course. 1836 Grand Liverpool Steeplechase The 1836 Grand Liverpool Steeplechase was the first of three unofficial annual precursors of a steeplechase which later became known as the Grand National. The steeplechase was held at Aintree Racecourse near Liverpool, England on 29 February 1836 and attracted a field of ten runners. The winning
