Patent ID: 7939700

Claim:
In a process for alkylation of a feedstock comprising benzene and propylene alkylating agent to form an alkylation product comprising cumene and diisopropylbenzene in which said process comprises contacting said feedstock in at least partial liquid phase under alkylation conditions including a temperature of from about 0° C. to about 500° C., a pressure of from about 20 to about 25000 kPa-a, a molar ratio of benzene to propylene alkylating agent of from about 0.1:1 to about 50:1, and a feed weight hourly space velocity (WHSV) based on the propylene alkylating agent of from about 0.1 to about 500 hr −1 , with a catalyst composition in the form of a quadrulobe extrudate comprising crystalline UZM-8 zeolite and an alumina binder, the improvement comprising conducting said process in the presence of said catalyst composition having a weight ratio of crystal/binder of from about 20/80 to about 60/40; wherein the diisopropylbenzene to cumene selectivity is less than about 14%.
