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.

Process for producing cumene

A method for producing phenol is disclosed which includes oxidizing cumene to form cumene hydroperoxide and acid cleavage to form cumene, phenol, acetone, and various byproducts, including alpha methylstyrene, followed by a subsequent hydrogenation of at least a part of the acetone and substantially all of the alpha methylstyrene.

Hydrogenation of cleavage effluents in phenol production

A process is disclosed for pretreating a dilute ethylene feedstock with benzene, ethylbenzene, or mixtures thereof to reduce the higher olefin content of the ethylene feedstock and to render it suitable as the feed to an alkylation reactor for producing ethylbenzene. Benzene and ethylbenzene recovery are integrated with other downstream operations in the ethylbenzene production.
