Abstract
Relatively short chain alkyl aromatic compounds are prepared by alkylating an alkylatable aromatic compound with a relatively short chain alkylating agent under alkylation reaction conditions in the presence of catalyst comprising a synthetic porous crystalline material characterized by an X-ray diffraction pattern including interplanar d-spacings at 12.36.+-.0.4, 11.03.+-.0.2, 8.83.+-.0.14, 6.18.+-.0.12, 6.00.+-.0.10, 4.06.+-.0.07, 3.91.+-.0.07 and 3.42.+-.0.06 Angstroms.
Claims26
A process for preparing short chain alkyl aromatic compounds which comprises contacting at least one alkylatable aroxatic compound with at least one alkylating agent possessing an aliphatic group having from 1 to 5 carbon atoms under alkylation reaction conditions and in the presence of an alkylation catalyst to provide an alkylated aromatic product possessing at least one alkyl group derived from said alkylating agent, said catalyst comprising a synthetic porous crystalline material characterized by an X-ray diffraction pattern including values substantially as set forth in Table A of the specification.
A process for alkylating an alkylatable polynuclear aromatic hydrocarbon which comprises contacting the alkylatable polynuclear aromatic hydrocarbon with an olefinic alkylating agent having from 2 to 5 carbon atoms under alkylation reaction conditions and in the presence of an alkylation catalyst selected from the group consisting of a synthetic porous crystalline material characterized by an X-ray diffraction pattern including values substantially as set forth in Table A of the specification.
