ABSTRACT:
Alkylatable aromatic hydrocarbons are alkylated with olefins and alkylhalides under anhydrous alkylating conditions in the presence of certain metallic cation exchanged synthetic hectorite-type catalysts in which the metallic cation has a Pauling electronegativity greater than 1.0 and in which the central octahedral layer contains one or more divalent metals which have an ionic radius not greater than 0.75 A. In a specific embodiment, 1-dodecene is reacted with benzene by contacting the dodecene and benzene under anhydrous alkylating conditions in the liquid phase at the boiling point of the mixture with a catalyst comprising a metallic cation such as Al.sup.3+, In.sup.3+, and Cr.sup.3+ exchanged onto the surface of a synthetic nickeliferous hectorite.
