中文摘要：

1-butyl-3-methylimidazolium 高氯酸盐([BMIM ] ClO4 ) 被二步与 N-methylimidazolium 综合。一些物理化学的性质例如密度，表面紧张，粘性，电的传导性以及电气化学的窗户，被调查，溶剂性能也被学习。结果证明这种离子的液体是有低粘性，高电的传导性和宽电气化学的窗户的优秀电解质。另外，[BMIM ] ClO4 在很常规的溶剂是可溶的，一些金属氧化物在它有高溶解度，它在这离子的液体打金属氧化物的直接电解的基础。

英文摘要：

1-butyl-3-methylimidazolium perchlorate（[BMIM]ClO4） was synthesized by two steps with N-methylimidazolium.Some physico-chemical properties,such as density,surface tension,viscosity,electrical conductivity as well as electrochemical window,were investigated and solvent performance was also studied.The results show that this kind of ionic liquid is an excellent electrolyte with low viscosity,high electrical conductivity and wide electrochemical window.In addition,[BMIM]ClO4 is soluble in most conventional solvents and some metal oxides have high solubility in it,which lays the foundation of direct electrolysis of metal oxides in this ionic liquid.
