Patent ID: 7655824

Claim:
A process for producing alkylaromatic compound comprising contacting at least one aromatic compound and at least one acyclic mono-olefin of 6 to 40 carbon atoms per molecule in a molar ratio of aromatic compound to mono-olefin between about 5:1 to about 10:1 with solid catalyst under alkylation conditions comprising the presence of catalyst containing small crystal, acidic Y zeolite to provide an alkylation product comprising alkylaromatic compound wherein the Mono-alkylated Alkylaromatic Selectivity is at least about 92, wherein the Y zeolite has a major crystal dimension of from about 50 to about 300 nanometers and where the amount of dialkylbenzene in the alkylation product is reduced by at least 40 mass-% as compared to when the Y zeolite has a major crystal dimension of about 1.5 microns.
