摘　　要：在微波辐射下 ,以活性炭负载磷钨酸 (HPW/C)为催化剂 ,不用溶剂 ,合成了苯乙酸 β 苯乙酯。优化反应条件为 :负载量为 2 3 .6%的HPW /C 1g ,苯乙酸 3 0mmol,β 苯乙醇 4 8mmol,微波辐射功率 60 0W ,辐射时间 6min ,产率 87.3 %。产物结构经IR表征。Phenylethyl phenylacetate was synthesized from phenylacetic acid with β-phenylethyl alcohol using phosphotungstic acid supported on active carbon(HPW/C) as the catalyst under solvent-free condition and microwave irradiation.Under the optimum reaction conditions[HPW/C(loaded amount 23.6%) 1g, phenylacetic acid 30mmol, β-phenethyl alcohol 48mmol, microwave power 600W, microwave irradiation time 6min), the yield of ester was 87.3%. The product was characterized by IR.
