An aromatic hydrocarbon. Also known as isopropylbenzene or cumol. It is derived from cumin oil, an essential oil obtained from the caraway plant , Cuminum cyminum . Industrially, it is produced by subjecting benzene to the Friedel-Crafts reaction with propylene. It is insoluble in water, but soluble in various organic solvents. It was once used as a blending agent for high-octane gasoline. It is also a raw material for the synthesis of phenol and acetone by the cumene process.
