Alkyl aromatic compounds are prepared by reacting at alkylation conditions 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 comprising 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 and calcining the resultant extrudate. This catalyst enables improved selectivity for the desired linear alkyl aromatic compound which may then be used in the preparation of biodegradable detergents. |
