Cumene phenol
The cumene process (cumene-phenol process, Hock process) is an industrial process for synthesizing phenol and acetone from benzene and propylene. The term stems from cumene (isopropyl benzene), the intermediate material during the process. It was invented by R. Ūdris and P. Sergeyev in 1942 … See more Cumene is formed in the gas-phase Friedel–Crafts alkylation of benzene by propene.

WebCumene is an important intermediate used in the production of phenol and acetone, and the growth of various end-use industries has increased its demand. About 95% of the cumene produced is used for this purpose. Phenol and acetone are used in a variety of industries, including cosmetics, pharmaceuticals, paints and coatings, and aerospace. Webhydroperoxide (CHP) cleavage into phenol and acetone. The cumene oxidation reaction has been known since 1926 [3], i.e., for a relatively long period of time, prior to the discovery of the abovementioned CHP cleavage reaction. The original practical purpose of cumene oxidation was the production of acetophenone, rather than of CHP [4].
WebCumene is extensively used in phenol and acetone production. It is applied as an intermediate in the industry; for instance, cumene is a chemical intermediate in dicumyl peroxide production.
