摘要： 研究了纳米固体超强酸SO42-/ZrO2催化松油醇乙酰化反应。通过正交试验得出反应的最佳工艺条件:反应温度50℃,反应时间5h,催化剂用量3%,乙酐和松油醇摩尔比(酐醇比)为1.3:1。在此条件下进行稳定性实验,产物中总酯的含量为92.79%,主要副产物柠檬烯和异松油烯的含量为5.27%,松油醇的转化率100%;催化剂的活性和选择性都优于普通固体超强酸,而且可重复使用5次。

Abstract: The nanometer solid superacid SO42-/ZrO2 was used as catalyst for acetylating of terpineol. By orthogonal tests, the optimum technology condition was obtained. The optimum temperature and time were (50℃) and 5 h, respectively, catalyst quantity was 3%, the ratio between acetic anhydride and terpineol was (1.3:1.) Under this condition, the conversion ratio of terpineol was 100%, the total ester was 92.79%, the content of lemonene with carene as main byproducts was 5.27% among products. The activity and selectivity of the nanometer solid superacid SO42-/ZrO2 were higher than those of ordinary solid superacid SO42-/ZrO2. The nanometer solid superacid SO42-/ZrO2 could be repeatedly used for 5 times.

Key words: nanometer particles, solid superacid, SO42-/ZrO2, terpineol, acetylation
