PURPOSE:To obtain the titled substance useful as a raw material for polymers, intermediate for dyes, medicines.agricultural chemicals, etc., in high conversion, by reacting an aromatic hydrocarbon with an alkylating agent in the presence of a mordenite type zeolite catalyst treated with a fluorine-containing compound. CONSTITUTION:An aromatic hydrocarbon, particularly biphenyl is reacted with an alkylating agent, e.g. olefin, aliphatic lower alcohol or alkyl halide, in the presence of a mordenite type zeolite catalyst, preferably hydrogen ion exchange type treated with a fluorine-containing compound in the vapor or liquid phase to afford the titled substance. The above-mentioned catalyst is obtained by a method for treating, e.g. dipping mordenite type zeolite in a 5-20wt.% aque ous hydrofluoric acid, etc., for 2-10hr and firing the zeolite in an inert gas atmosphere, bringing the mordenite zeolite into contact with a gaseous fluorine- containing compound, e.g. CFCl3, etc., at 300-600 deg.C, etc. The reaction tempera ture is 200-250 deg.C for the vapor phase or 150-250 deg.C for the liquid phase.
