WebCumene process is one of the important methods followed for the industrial preparation of acetone. In cumene process, acetone and phenol are synthesized from the reaction of propylene and benzene in the presence of oxygen. The precursors used in this process are cheap and the reaction is carried out easily. 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.
