PRODUCTION OF DIOLEFINS
Diolefins are hydrocarbon compounds that have two double bonds. Conjugated diolefins have two double bonds separated by one single bond. Due to conjugation, these compounds are more stable than monoolefins and diolefins with isolated double bonds. Conjugated diolefins also have different reactivities than monoolefins. The most important industrial diolefinic hydrocarbons are butadiene and isoprene.
