ABSTRACT:
Disclosed is a method for the preparation of cumene by reacting isopropanol or a mixture of isopropanol and propene with benzene in the presence of a β-zeolite catalyst having a SiO2/Al2O3molar ratio greater than 10:1 that can be integrated in a process for preparing phenol, which comprises preparing cumene as described above, oxidizing cumene to cumene hydroperoxide, acid-catalyzed cleavage of cumene hydroperoxide to give phenol and acetone, and hydrogenating acetone to form isopropanol.
