摘　　要：以邻苯二胺、甲酸为起始原料,通过缩合反应合成苯并咪唑,在碱性条件下苯并咪唑与苄基氯反应合成N-苄基苯并咪唑,然后将其与溴乙烷反应,得到溴化1-苄基-3-乙基苯并咪唑盐离子液体。所得产品结构经FTIR、1H NMR、13CNMR以及LC-MS表征,证明为目标产物。With o-phenylendiamine and formic acid as starting material, benzimidazole was synthesized by the conden-sation reaction. Under the alkaline conditions, N-benzylbenzimidazole was prepared by the reaction of benzyl chloride with benzimidazole, then N-benzylbenzimidazole reacted with bromine bromoethane and Bromide1-ben-zyl-3-ethyl-benzimidazolium ionic liquids were obtained. The structure of products were characterized by FTIR, 1H NMR, 13C NMR spectrum and LC-MS.
