摘要： 合成了一系列由磺酸基、 羧基修饰的新型功能化苯并咪唑类离子液体, 采用IR, 1H NMR, 13C NMR和ESI-MS对其结构进行了表征, 研究了化合物的热稳定性、 电导率以及室温下在各种溶剂中的溶解性等性质. 结果表明, 该类离子液体在 280 ℃以下基本没有失重, 热稳定性较好; 在水溶液浓度为1×10-3 mol/L时, 随着温度的升高, 电导率几乎与温度呈正比增大; 能与大多数有机溶剂互溶, 溶解性随着溶剂极性的增加而增大.

关键词: 功能化离子液体, 苯并咪唑, 溶解性, 热稳定性, 电导率

Abstract: A series of functionalized ionic liquids based on benzimidazolium cation was synthesized and cha-racterized by 1H NMR, 13C NMR, IR and ESI-MS. The thermal stability, electrical conductivity, the solubility in various solvents and other properties were studied. The results showed that the ionic liquids had no weight loss under 280 ℃, indicating they have a good thermal stability. When the concentration of the ionic liquids in the aqueous solution is 1×10-3 mol/L, increasing the conductivity is almost proportional to the temperature increases, miscible with most organic solvents, solubility with the increase of solvent polarity.

Key words: Functionalized ionic liquids, Benzimidazole, Solubility, Thermal stability, Conductivity
