Green synthesis of 2- (4′- ethylbenzoyl)- benzoic acid (BEA) was realized by the condensation reaction for the first time, with water as solvent, heat treated alum as a catalyst, ethylbenzene and phthalic an-hydride as materials. 2- ethylanthraquinone (2- EAQ) was synthesized through dehydration closed loop reac-tion. BEA and 2- EAQ were analyzed through the qualitative analysis. The optimal BEA synthesis conditions were: the feeding rate of phthalic anhydride was 0.12 g/min, reaction temperature was 40 ℃, and the stirring speed was 520 r/min.
