摘　　要：以乙酸和环己醇为原料,磷钨酸为催化剂合成乙酸环己酯,通过设计正交实验确定了酯化反应的影响因素。最佳反应条件为:醇酸摩尔比为1∶1.5,催化剂用量为0.4 g,反应时间为2.5 h,带水剂为3 m L,酯化率可达80.39%。Cyclohexyl acetate was synthesized with acetic acid and cyclohexanol as raw materials, phosphotungstic acid as catalyst. The optimum reaction conditions were investigated by the design of orthogonal experiment. The results show that the optimum reaction conditions are as follows： molar ratio 1：1.5, catalyst dosage 0.4g, and reaction time 2.5h, water-carrying agent 3ml;Under above conditions, the esterification rate can reach to 80.39%.
