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, 1-dodecene is reacted with benzene by contacting the dodecene and benzene under anhydrous conditions in the liquid phase at the boiling point of the mixture with a catalyst comprising a metallic cation such as Al3<+>, In3<+> and Cr3<+> exchanged onto the surface of hectorite clay.
