本文利用正交试验找到用SO42-/TiO2-Al2O3固体超强酸催化合成乙酸正戊酯的最佳反应条件.即反应时间3.0h,催化剂用量为酸质量的1.0%,酸醇比1∶2,验证实验产率为96.2%.且该实验反应时间短,无腐蚀无污染,催化剂可回收可重复使用.

By using the orthogonal test method synthesis of n-Amyl Acetate with solid superacid SO_4^(2-)/TiO_2-Al_2O_3.The factors influencing the yield of product and the optimum reaction conditions were discussed .The optimum conditions are as follows: the molar ratio of acid to alcohol was 1∶2,quantity of catalyst is equal to 1.0% feed stock ,and the reaction time is 3 hour .the yield can be up to 96.2%.
