| 摘 要： | 将高氯酸分别溶解于[(C2mim)BF4]、[(C4mim)BF4]和[(C8mim)BF4]制备了3种酸性离子液体复合催化剂，用于催化油酸的聚合反应，结果表明：[HClO4-(C4mim)BF4]的催化效果最佳。以[HClO4-(C4mim)BF4]为催化剂，考察了n(油酸)∶n(高氯酸)∶n(月桂酸)∶n[(C4mim)BF4]、反应温度和反应时间等条件对反应结果的影响。在n(油酸)∶n(高氯酸)∶n(月桂酸)∶n[(C4mim)BF4]＝1∶0.7∶0.5∶0.5、45 ℃、24 h 的较佳工艺条件下，交内酯（estolides）的收率88％，倾点－17 ℃。此催化剂可以循环利用5次，实现了交内脂的绿色合成。

| Abstract: | HClO4 was dissolved in [(C2mim) BF4], [(C4mim)BF4] and [(C8mim) BF4] respectively and used as a compound catalyst in the polymerization of oleic acid. The results showed that [HClO4-(C4mim)BF4] had the highest catalytic activity. Using [HClO4-(C4mim)BF4] as catalyst, under the optimum reaction condition of n(oleic acid): n(HClO4)∶n(lauric acid)∶n[(C4mim)BF4]=1∶0.7∶0.5∶0.5, reaction temperature 45℃ and reaction time 24h, the yield of estolides was 88％，and its pour point reached －17℃. [HClO4-(C4mim)BF4] could be reused 5 times in this reaction system，and the green synthesis of estolides was realized. |
