摘要
以N-甲基咪唑为原料合成了室温离子液体1-丁基-3-甲基咪唑氯酸盐([BMIM]ClO3),用IR、NMR、DSC-TGA等手段对产物进行了表征,测定了相关物化性能,如密度、表面张力、黏度、电导率和电化学窗口等,并考察了该离子液体的溶剂性能。结果表明,该离子液体作为新型的电解质材料,具有低黏度、高电导率,密度、表面张力、黏度均随温度升高而减小,电导率随温度升高而增大,与温度符合Arrhenius方程。该离子液体与多数常规溶剂互溶,并对某些金属氧化物具有较高的溶解度,为离子液体在选矿、电解金属氧化物等方面的应用奠定了基础。
1-butyl-3-methylimidazolium chlorate （[BMIM] ClO3 ） was .synthesized with N-methylimidazolium and characterized by IR, NMR and DSC TGA. Some physical chemistry properties concerned, such as density, surface tension, viscosity, electrical conductivity as well as electrochemical window, were investigated and sol- vent performance was also studied. The results show that this kind of ionic liquid is a new excellent electrolyte with low viscosity, high electrical conductivity. All of density, surface tension and viscosity of the ionic liquid decrease with increase of temperature. While electrical conductivity increases with increasing temperature and in accord with Arrhenius equation. In addition, the ionic liquid is soluble in most conventional solvents and some metal oxides have high solubility in it, which lays the foundation of applying it in the fields such as mineral sep- aration and direct electrolysis of metal oxides.
