摘要
利用正交试验找到用SO42-/TiO2-Fe2O3固体超强酸催化合成丁酸丁酯的最佳反应条件。即反应时间4.0h,催化剂用量为酸质量的1.4%,酸醇比1.2:1,验证实验产率为97.6%。且该实验反应时间相对短,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-butyl butyrate with solid superacid SO4^2-/TiO2-Fe2O3 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 1.2:1,quantity of catalyst is equal to 1.4% feed stock ,and the reaction time is 4 hour .the yield can be up to 97.6%.
