摘　　要：介绍了无卤离子的离子液体的3种合成方法,即直接酯化法、复分解法和卡宾法,并对其反应机理加以分析.认为采用合适的溶剂可以除去两步法中的卤素离子杂质,但采用各种酯对咪唑直接进行季铵化反应的收率高、步骤短;用卡宾制备的离子液体纯度高.Three methods for the synthesis of ironic liquids without halogen ion were introduced ： direct esterification ,metathesis and carben. And their reaction mechanism was introduced. It was pointed out that suitable solvents could be used to remove the halogen ion impurity in the two steps, but ionic liquids can be synthesized by the reaction of imidazole and the esters with high yield. Ionic liquids obtained by the carben have high purity.
