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
Agamassan Agamassan Agamassan is a porous substrate used to safely absorb acetylene and thus allow the transport, storage and commercial exploitation of the otherwise unstable gas. It was developed and patented by the Swedish Nobel Laureate and industrialist Gustaf Dalén. Dalén was prominent in developing applications for acetylene. Acetylene can readily explode when in liquid or solid form or while being pressurized, if it is pure. Dalén himself was blinded in an acetylene explosion. In 1896, French chemists Georges Claude and Albert Hess discovered that large quantities of acetylene could be dissolved in acetone and rendered nonexplosive. As the liquid was
