| 摘 要： | 对叔丁基苯乙酸在浓硫酸催化下，采用微波常压法与甲醇合成对叔丁基苯乙酸甲酯。结果表明：当对叔丁基苯乙酸：甲醇：浓硫酸=2：20：0．75(摩尔比)，采用600w微波辐射20min时，对叔丁基苯乙酸甲酯的产率达93．6％，反应速率是常规方法的12倍。

| Abstract: | The synthesis of methyl 4-tert phenylacetate with methanol and 4-tert phenylacetic acid as reactants and normal pressure with concentrated H 2SO 4 as a catalyst under microwave irradiation is studied. When the molar ratio of 4-tert phenylacetic acid: methanol:H 2SO 4=2:20:0.75 and the irridiation time of 600W was 20min, the yields of the esterfication are 93.6%. The reaction under microwave is at least 12times as fast as that under ceassical condition. |
