Preparation
Acetylene is the simplest alkyne and stands out from the industrial point of view. Acetylene can be directly produced from coal following two main industrial procedures:
Marcellin Berthelot (1827-1907): French chemist and politician. He showed that glycerol is a triol and prepared ethanol, formic acid, methane, acetylene and benzene at a time when the vital force theory was still strongly held. He obtained acetylene by subjecting a mixture of coal and hydrogen to the high temperatures of an electric arc. He is considered the father of thermochemistry, because he began the systematic study of the heat absorbed or released in chemical reactions.
