Uses

Propene is produced from fossil fuels, and from coal. Propene is the second most important product used in the petrochemical industry, after ethene. About two thirds are used to produce polypropylene. Propene and benzene are converted to acetone and phenol via the cumene process. Propene is also used to produce isopropanol (propan-2-ol), acrylonitrile, propylene oxide (epoxypropane) and epichlorohydrin.
