Abstract
A process for producing 2,6-dimethylnaphthalene by alkylation of an alkylaromatic, e.g. toluene, with a C.sub.5 olefin alkylating agent, e.g. 1-pentene, in the presence of a suitable alkylation catalyst, and dehydrocyclization of the resulting alkylate with a dehydrocyclization catalyst to generate a dimethylnaphthalene product rich in the 2,6-isomer. Additional process steps can include isomerization of the product and further alkylation.
