摘　　要：在微波辐射功率为250W反应25min的条件下，水杨酸分别与甲醇、乙醇、丙醇、异丙醇、叔丁醇在离子液体作溶剂和催化剂下发生酯化反应，得到了水杨酸甲酯、水杨酸乙酯、水杨酸丙酯、水杨酸异丙酯、水杨酸叔丁酯，收率85．95％，产物结构经1HNMR和元素分析进行了确认。Using NaHSO4 · H2O as the catalyst, five important organic intermediates, methyl chloroacetate, ethyl chloroacetate, n-propyl chloroacetate, iso-propyl chloroacetate and tert-butyl chloroace- tate were obtained in 76%- 91% yields from chloroacetic acid and the corresponding alcohols under microwave irradiation at 250 W for 10 min. All products were identified by 1H NMR, and elementary analysis.
