Cumene phenol
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. http://www.plastics-technology.com/pressreleases/lummus-announces-acceptance-of-cumene-and-phenol-plant-in-china
