摘要: 以氯化胆碱、丙二酸为原料合成了一种无色、均匀的氯化胆碱-丙二酸室温离子液体。通过傅里叶红外光谱仪对该离子液体的结构进行了初步分析,考察了该离子液体的电导率、黏度、密度等性质及与温度的变化关系,并采用循环伏安测试法对该离子液体的电化学窗口进行了分析。结果表明:温度对该离子液体的物理化学性质的影响非常明显,该离子液体的电化学窗口较宽,是一种较理想的电沉积溶液。

Abstract: A homogeneous, colorless ionic liquid at room temperature was prepared by using choline chloride and malonic acid as raw materials. The structure of the ionic liquid was preliminarily analyzed by Fourier transform infrared spectroscopy(FT-IR). The properties of conductivity, viscosity and density of choline chloride-malonic acid ionic liquid as a function of temperature were investigated, and the electrochemical window of this ionic liquid was tested by the cyclic voltammetry method. The results showed that the properties of the ionic liquid were affected greatly by the temperature, and the as-prepared ionic liquid with wider electrochemical window was a kind of ideal solvent.
