摘　　要：氯化胆碱经氯磺酸化得到的N,N,N-三甲基-N-磺酸氧乙基氯化铵([Ch-OSO_(3)H]Cl),能够催化蓖麻油与甲醇进行酯交换反应,制备生物柴油。考察了反应温度、反应时间、物料比等对酯交换反应的影响。结果表明:在优化工艺条件下,n(蓖麻油)∶n(甲醇)为1∶8、催化剂用量为蓖麻油质量的8%、70℃下反应8 h,生物柴油产率为92%,催化剂可以回收并循环使用。N,N,N-trimethyl-N-(sulfooxy)ethanaminium chloride([Ch-OSO_(3)H]Cl)was prepared from choline chloride and chlorosulfonic acid.[Ch-OSO_(3)H]Cl was proved to be a novel and efficient catalyst for the synthesis of biodiesel from castor oil and methanol in good yield of 92% under optimal reaction conditions:molar ratio of methanol to triolein at 8∶1,mass fraction of ionic liquid 8%,reaction temperature 70℃ and reaction time 8 h,and the catalyst was stable during the reaction and could be reused.
