Description and Uses

Cyclohexene is a hydrocarbon, mostly obtained from the hydrogenation of benzene.

It occurs in coal tar and is obtained by catalyticdehydration of cyclohexanol and dehydrogenationof cyclohexane. Cyclohexene isused in making adipic acid, maleic acid,and butadiene; in oil extraction; as a stabilizerfor high-octane gasoline; and in organicsynthesis.
