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.
