Ketene

Ketene is a colorless, poisonous gas that is an irritant of the lungs, and it is used chiefly as an acetylation agent.

Chemical Formula: C₂H₂O

Other names: Ketene

Layman's explanation: Ketene was discovered by N.T.M Wilsmore, and it was found that ketene readily absorbs UV light. It is very easily polymerized, and it has many uses. Its primary use is in the manufacturing of acetic anhydride, diketene, and sorbic acid. In 1997, the U.S. consumption was over 500 million pounds and this number is still growing. When ketene is allowed to react with oxygen, it is rapidly converted into a white explosive solid. Diketene is produced by the autodimerization of ketene which is a more stable product that can be stored for weeks under refrigeration.

Keywords: irritant, acetylation agent, autodimerization
