Production of alkyl aromatic compounds

摘要

Alkyl aromatic compounds may be prepared by reacting an aromatic compound with an alkylating agent such as an olefin in the presence of an alkylation catalyst. The alkylation catalyst of the present invention comprises a composite which has been prepared by coextruding a clay component and at least one multi-valent metal component in which the metal is selected from the group consisting of Groups IIIA, IIIB and IVB of the Periodic Table, followed by drying the resultant extrudate and calcination thereof. By utilizing a catalyst which has been prepared by this method in an alkylation reaction it is possible to obtain an improved alkylate selectivity.
