Patent ID: 7790940

Claim:
In a process for alkylation of feedstock comprising at least one alkylatable aromatic compound and an alkylating agent to an alkylation product comprising an alkylaromatic compound which comprises contacting said feedstock in at least partial liquid phase under catalytic 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 alkylatable aromatic compound to alkylating agent of from about 0.1:1 to about 50:1, and a feed weight hourly space velocity (WHSV) based on the alkylating agent of from about 0.1 to about 500 hr −1 , with a catalyst composition comprising crystalline MCM-22 or MCM-49 zeolite and an alumina binder having a ratio of crystal/binder of from about 20/80 to about 60/40; wherein the dialkylbenzene to monoalkylbenzene selectivity is less than about 14%.
