Abstract: Esterification of rosin with ethanol under microwave irradiation was studied.Acid value of ethyl rosinate was 3.88 mgKOH/g by reacting rosin with ethanol in the presence of p-toluenesulfonic acid under microwave irradiation for 24 min.Dosage of catalyst is 12%-16% and ethanol is 2-3 times(on the basis of rosin mass).

Key words: rosin, ethanol, microwave irradiation
