摘　　要：以均匀设计安排实验,在强酸性阳离子交换树脂催化剂的作用下,快速合成了乙酸异戊酯,实验结果经过优化组合,得出最佳反应条件为:异戊醇与冰乙酸物质的量的比为0.75,催化剂重复次数为10次,回流时间为1.7h。同时,对树脂的重复使用性能进行了测试,结果表明:树脂在使用10次后,其催化性能保持不变。Uniform design is adopted in this experiment. The isoamyl acetate is finally synthesized with the strong acidic resin as catalyst. Optimum reaction conditions are as follows:molar ratio of alcohol and acid 0.75, repetition of catalyst 10 times, refluxing time 1.7 h. Moreover, the recycle of the resin is also tested, and the result shows that it has the same function as catalyst even though the resin has been used repeatedly for 10 times.
