摘　　要：With activated carbon supported tungstosilicic acid as catalyst,isoamyl propionate is synthesized directly under normal pressure and microwave irradiation.The configuration of samples is characterized by IR and NMR.The most suitable reaction conditions are 1.60 g activated carbon supported tungstosilicic acid,1.0∶1.3 of the mole ratio of acid to alcohol,the microwave irradiation time is 12 min and the amount of the agent taking off water 7 mL.The conversion rate of propionie acid is over 90% under the above reaction conditions.Repeated tests show the catalyst have good repeatability.With activated carbon supported tungstosilicic acid as catalyst, isoamyl propionate is synthesized directly under normal pressure and microwave irradiation.
