摘　　要：采用微波间歇辐照方法研究了微波辐照下乙酸松油酯的合成,确定的最适工艺条件为:催化剂磷酸-乙酐用量为原料松油醇质量的4%、微波功率100 W、反应时间2 h、酐醇比1.25∶1。最适工艺条件下,松油醇转化率为96.92%、乙酸松油酯产率为86.53%,其效果均比常规加热下明显提高,且反应时间仅为常规的1/8。The technology of synthesizing terpineyl acetate has been studied by using the method of batch-wise microwave irradia- tion. The results showed that the optimized conditions were as the follows ; ratio of acetic anhydride to terpineol was 1.25 ： 1,4 % acetic anhydride and phosphoric acid were used as catalyst （based on terpineol mass） under 100 W microwave, and irradiation time was 2 h. The conversion of terpineol was 96.92 % and the yield of terpineyl acetate was 86, 53 % under optimum conditions. Compared with normal methods, it had higher efficiency, only one eighth reaction time of normal method was needed.
