中文摘要：

以N-甲基咪唑为原料合成了1-丁基-3-甲基咪唑硫酸氢盐（[BMIM]HSO4）室温离子液体，对产物进行了表征，测定了相关物化性能，如密度、表面张力、黏度、电导率等，并考察了该离子液体的溶剂性能。实验发现，该离子液体电导率与常见离子液体电导率相当，并符合Arrhenius方程，密度、表面张力、黏度均随温度升高而减小。该离子液体与多数常规溶剂互溶，并对金属氧化物具有一定的溶解度，为在离子液体中直接电解金属氧化物奠定了基础。

英文摘要：

1-butyl-3-methylimidazolium hydrosulfate （ [ BMIM] HSO4 ） was synthesized with N-methylimidazolium and characterized. Some physical chemistry properties concerned, such as density, surface tension, viscosity, and electrical conductivity, are investigated and solvent performance is also studied. It is discovered from the experiments that this kind of ionic liquid has comparative electrical conductivity with familiar ionic liquids and the electrical conductivity follows the Arrhenius equation. Density, surface tension as well as viscosity of the ionic liquid decrease with increase of temperature. In addition, the ionic liquid is soluble in most conventional solvents and metal oxides have some solubility in it, which lays the foundation of direct electrolysis of metal oxides in ionic liquids.
