Abstract

Abstract Alkylatable aromatic hydrocarbons are alkylated with olefins and alkylhalides under anhydrous alkylating conditions in the presence of a metallic cation exchanged trioctahedral 2:1 layer-lattice smectite-type catalyst in which the metallic cation has a Pauling electronegativity greater than 1.0. In a specific embodiment, there is provided a catalyst comprising a trioctahedral smectite-type clay having the structural formula:
