Acetylene Properties

Share |

Acetylene is a colourless gas with a pleasant odour. It usually contains traces of phosphine that cause an unpleasant garliclike odour. It is stored in a high pressure cylinder filled with a porous material and containing acetone. Acetylene can be decomposed to its elements with the liberation of heat. It can decompose spontaneously of pressure exceeds 15 PSIG.

Acetylene is manufactured by the reaction of water with calcium carbide. It is also manufactured by thermal cracking of hydrocarbons, or by partial combustion of methane and oxygen.
