| 摘 要： | 以HF-101强酸型离子交换膜力催化剂，由草酸与异戊醇为原料合成了草酸二异戊酯，考察醇酸摩尔比，反应时间，催化剂用量对酯化率的影响。最佳合成条件为：醇酸摩尔比3：1，反应时间3.5h，催化剂用量2.0g，反应温度为回流温度。在此条件下，酯化率达90.6%。催化剂重复使用7次，酯化率仍达81.17%。

| Abstract: | Diisopentyl oxalate was synthesized by the esterification of oxalic acid and isopentyl alcohol in the presence of HF-101 strong acidic ion exchange membrane. The effects of reaction time,amount of the catalyst, and molar ratio of alcohol/acid on the esterification were investigated.The esterification yield was up to 90.6% under the optimum condition. The esterification yield was still up to 81.1% after the catalyst was reused 7 times. |
