介绍了一种由氯化铝和三烷基咪唑卤化物制备的新型熔盐体系的制备和表征，特别是由1，2-二甲基-3-丙基咪唑氯化物制备的熔盐。用该盐制备的熔融盐在约100 ℃的组成范围内是液体。在25°C下为0.65：1至2.2：1。通过电位滴定法测定酸碱平衡常数的值。循环伏安法的结果比较MEICl和DMPrICl的还原电位和各自的熔融盐的电化学窗口。对于1：1的熔融盐，在玻璃碳上获得了近5V的电化学窗口。
The preparation and characterization of a new molten salt system prepared from aluminum chloride and a trialkylimidazolium halide is described, particularly those molten salts prepared with 1,2‐dimethyl‐3‐propylimidazolium chloride. Molten salts prepared with this salt are liquid over the composition range of ca. 0.65:1 to 2.2:1 at 25°C. A value for the acid‐base equilibrium constant of was determined by potentiometric titration. Cyclic voltammetry results are presented comparing reduction potentials for MEICl and DMPrICl and the electrochemical windows of the respective molten salts. For a 1:1 molten salt, an electrochemical window of nearly 5V is obtained at glassy carbon.
