Abstract: Iso-butyl gallate was synthesized by esterification of gallic acid with iso-butyl alcohol catalyzed by p-toluenesulfonic acid(PTSA) under microwave irradiation. The optimum reaction condition was as follows: molar ratio of gallic acid to iso-butyl alcohol 1:17, molar ratio of gallic acid to catalyst 1:0.05, microwave irradiation power 510 W (gallic acid 10.94 g), for 60 min. Average yield of iso-butyl gallate was 86.3%.

Key words: microwave irradiation, esterification, iso-butyl gall
