Abstract

PW 12/C phosphotungstic acid supported on active carbon were prepared and the optimum reaction conditions catalyzed synthesis of isoamyl hexanoate has been studied. Experiment finds that the catalyst is highly activity. As carry water reagent with cyclohexane ,molar ratio of isoamyl alcohol to hexanoate acid is 1.3∶1, the weight of catalyst is 2.5g/0.2mol hexanoate acid , and the reaction time is 120 min ,the esterification yield can reach over 99.1% .
