【Abstract】 Isoamyl Benzoate was synthesized with tungstosilicic acid as catalyst and methyl-benzene as water-carrying agent. The optimum raction conditions are alcohol acid mole ratio 1.5:1, catalyst amount 2.5% , reaction time 2.0 h and reaction temperature 120～130℃.The ester yield under this conditions was up to 96.4%.更多还原
