WebNov 4, 2013 · Alpha methyl styrene is hydrogenated back to cumene over a highly selective catalyst. The by-products and presence of azeotropes make the downstream separation of the products complex. Separation is done by a sequence of distillation units and phenol and acetone are obtained as pure products. 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.
