| 摘 要： | 合成了［HSO3-pmim］Cl、［HSO3-pmim］［H2PO4］、［HSO3-pmim］［BF4］和［HSO3-pmim］ ［HSO4］离子液体，用1H-NMR和FT-IR对离子液体的结构进行了确定。将几种酸功能化离子液体应用于三醋酸甘油酯的合成反应中，筛选出了一种催化效果好又可以重复使用的离子液体［HSO3-pmim］［HSO4］。考察了催化剂用量、原料配比和反应时间对反应的影响，得到了较佳反应条件：n(甘油)∶n（醋酸）=1∶8，催化剂用量为醇酸总质量的5.8%，反应时间6 h，反应温度(80~90) ℃。对该功能化离子液体的重复使用性进行了考察，重复使用10次后，三醋酸甘油酯的收率仍大于90%。

| Abstract: | ［HSO3-pmim］Cl、［HSO3-pmim］［H2PO4］、［HSO3-pmim］［BF4］and［HSO3-pmim］ ［HSO4］ ionic liquids were synthesized and their structures were characterized by 1H NMR and FT IR. Glycerol triacetate was synthesized using several acidic functional ionic liquids as the catalysts. ［HSO3 pmim］［HSO4］ had better catalytic results and could be repeatedly used. The influence of catalyst dosage, feed proportion and reaction time was investigated. The optimum condition was obtained as follows: n(glycerol)∶n(acetic acid)=1∶8, catalyst dosage 5.8% of the total weight of glycerol and acetic acid, reaction time 6 h, reaction temperature (80-90) ℃. Repeated use of the ionic liquid was investigated. Glycerol triacetate yield remained at over 90% after repeatedly use for 10 times. |
