FIELD: chemical industry. SUBSTANCE: method comprises reacting alkylbenzene with 1-phenylacetone in the presence of anhydrous aluminium chloride and subsequently maintaining the reaction mixture and insulating the desired product by well known method. Reaction is first charged with alkylbenzene and 1-chloro-1-phenylacetone, and anhydrous aluminium chloride is gradually added during stirring operation so that temperature of reaction mixture is not higher than 50 C. EFFECT: improved quality of the desired product and simplified technology. 5 ex
