摘要
以固体硫酸氢钠为催化剂催化合成异丁酸异丁酯,讨论了影响催化酯化的各种因素。其优化的反应条件为:n(异丁酸)∶n(异丁醇)=1∶3.0,n(催化剂)∶n(异丁酸)=0.04∶1、反应时间为2.0 h,此时异丁酸异丁酯的产率约为90%。
The synthesis of isobutyl isobutyrate with sodium hydrogen sulfate as catalyst was studied. The effects of reaction parameters were investigated and the optimum conditions were determined as follows： the molar ratio of iso butyric acid to isobutyl alcohol 1 ： 3. 0, the molar ratio of catalyst to iso butyric acid was 0. 04 ： 1, the reaction time was 2.0 h,and the yield of iso butyl iso butyrate was about 90%.
