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.

Abstract: In a process for producing cumene from acetone and benzene, a feed stream comprising acetone is contacted with hydrogen in the presence of a hydrogenation catalyst in a first reaction zone under hydrogenation conditions sufficient to convert at least part of the acetone to isopropanol and produce a first liquid effluent stream rich in isopropanol and a first vapor stream rich in unreacted hydrogen. Benzene is then added to at least part of the first liquid effluent stream, without intermediate purification of the first liquid effluent stream, and optionally to at least part of the first vapor stream, to form a second feed stream.

Abstract: 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.

Abstract: 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.
