Abstract

See full text

A process is described for producing cumene comprising contacting benzene and a C3 alkylating agent under alkylation conditions with an alkylation catalyst in an alkylation zone to produce an alkylation effluent comprising cumene and alkylaromatic compounds heavier than cumene. Cumene is recovered from the alkylation effluent to leave a byproduct stream containing the alkylaromatic compounds heavier than cumene, which is separated into a polyisopropylbenzene-containing stream, an aromatic overhead stream, and a bottoms product. At least part of the aromatic overhead stream is recycled to the alkylation zone to reduce raw material consumption and improve cumene yield.
