ABSTRACT:
Process for preparing 2-t-alkylanthracene, which process comprises contacting and reacting, with good mixing, at a temperature of at least 110.degree. C., anthracene and a branched-chain alkylating agent, the alkylating moiety of which contains at least four carbon atoms, in the presence of a catalyst selected from hydrocarbonsulfonic acids which are free of nonaromatic unsaturation, organic carboxylic acids having a K.sub.a of 0.6 to 0.001, acid zeolites, amorphous silica-aluminas, and polymeric arenesulfonic acid resins, to give a product mixture of which the major constituent is 2-t-alkylanthracene.
