摘　　要：文章合成了[Bmim]Im,ChIm与[N4222]Im三种单核咪唑碱性离子液体,采用红外、1H NMR、热重对其进行了表征分析。对三种离子液体催化大豆油酯交换合成生物柴油的活性进行了考察,结果发现[Bmim]Im碱性离子液体具有较高的催化活性。同时,对其酯交换相界面反应机理进行了探讨。Three mononuclear basic ionic liquids with an imidazolide anion group（[Bmim]Im,ChIm,[N4222]Im） were synthesized,and were characterized by FT-IR,1H NMR and TG.Three basic ionic liquids were employed as the catalysts for the synthesis of biodiesel by transesterification,and [Bmim]Im showed excellent catalysis performance.The possible mechanism of the transesterification reaction was also discussed.
