Abstract

A process is described for producing cumene comprising contacting a feed stream comprising benzene and a further feed stream comprising isopropanol or a mixture of isopropanol and propylene in the presence of an alkylation catalyst comprising at least a molecular sieve of the MCM-22, family in an alkylation zone under alkylation conditions of at least partial liquid phase and with a water concentration in the liquid phase of at least 50 ppm to react at least part of said isopropanol and benzene to produce an effluent stream containing cumene.
