WebCumene is manufactured by alkylation of benzene with propylene. In the phenol—acetone process, cumene is oxidized in the Hquid phase thermally to cumene hydroperoxide. The hydroperoxide is spHt into phenol and acetone by a cleavage reaction catalyzed by sulfur dioxide. Up to 2% of the cumene is converted to a-methylstyrene. WebCumene, or isopropylbenzene, is a valuable product that is used mainly for the manufacture of phenol and acetone. Cumene has been produced by a catalytic process using a solid phosphoric acid that is made by impregnating kieselguhr with phosphoric acid. Now, zeolitic catalysts are used to produce higher quality cumene at a lower investment cost.
