Abstract
Alkyl aromatic compounds may be prepared by reacting an aromatic compound such as benzene with an alkylating agent such as an olefin, alkyl halide or alkyl alcohol in the presence of an alkylation catalyst. The alkylation catalyst of the present invention comprises a pillared clay and a binder which has been prepared by dispersing a clay in a metallic pillaring agent sol, separating the resultant pillared clay, washing and drying said pillared clay, forming a dough of said pillared clay and a binder compound, extruding said dough extudate. By utilizing this catalytic composite it is possible to obtain improved selectivity of the desired alkyl aromatic compound which may then be used in the preparation of biodegradable detergents.
Claims14
A process for the production of an alkylaromatic compound which comprises reacting an aromatic compound with an alkylating agent selected from the group consisting of olefins, alkyl halides and alkyl alcohols at alkylating conditions in an alkylation zone in the presence of a catalytic composition of matter, said catalytic composition of matter having been prepared by dispersing a clay in a metallic pillaring agent sol, separating the resultant pillared clay, washing and drying said pillared clay, forming a dough of said pillared clay and a binder compound, extruding said dough and calcining the resulting extrudate, and recovering said alkyl aromatic compound.
