Abstract

A method of selective beta-alkylation of aromatic substrates such as naphthalene or a derivative thereof, comprising reacting the substrate with an alcohol or olefin alkylating agent in the presence of a catalyst selected from the group consisting of a crystallized borosilicate glass zeolite and a crystalline alumina-silica catalyst, said catalyst being at least 86% beta selective with respect to the alkylation of naphthalene by the alkylating agent.
