Synthesis of isoamyl acetate with supported phosphotungstic acid catalyst

Isoamyl acetate is synthesized from Acetic acid and Amyl alcohol with Supported Phosphotungstic Acid as catalyst.The effect of reaction factors on the yield of the product was discussed.The optimal reaction conditions are as follows:ratio of Amyl alcohol to acetic acid is 1.3:1,the weight of catalyst is 5% of acetic acid,reaction time is 150min,and water carring reagent cyclohexane is 7.5mL.The yield of Isoamyl acetate could reach about 80% under the optimum conditions.The result showed that the Supported Phosphotungstic Acid had good catalytic activity and stability.The catalyst can be used repeatedly at least for 5 times,which is friendly with the environment.
