A PROCESS FOR IMPROVING STABILITY OF ZEOLITE CATALYST TO USE IN CUMENE PRODUCTION BY ALKYLATION OF BENZENE WITH ISOPROPYL ALCHOL

摘要

The present invention relates to a process for improving stability of zeolite catalyst to use in cumene production by alkylation of benzene with isopropyl alcohol comprising contacting zeolite catalyst with silane compound in a certain condition. This results in the zeolite catalyst which is stable to water which is by-product of the reaction, providing longer ability to catalyze alkylation reaction.
