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
British Compressed Gases Association British Compressed Gases Association The British Compressed Gases Association is the UK's trade association for companies in the industrial (compressed) gases industry. It was formed in August 1971, succeeding the British Acetylene Association, which was formed in 1901. It used to be based in Wallingford, and also in Eastleigh. It represents companies that make, supply or distribute industrial gases in the UK, or sell related compression equipment. Use of these gases can be very dangerous due to the low temperatures of the products, and high pressures of the gas when released, and hence the organisation is involved in regulation and
