Abstract: A homogeneous, colorless ionic liquid analogous containing magnesium chloride is reported. The structure of the ionic liquid analogous is preliminary investigated by Fourier transform infrared spectroscopy (FTIR). The physico-chemical properties of ionic liquid analogous of choline chloride-urea-MgCl₂ such as viscosity, conductivity, density and CV are measured as a function of temperature at atmospheric pressure. The thermal expansion coefficients, the molar Gibbs energy of activation for viscous flow, the molar enthalpy of activation and the molar entropy of activation for viscous flow have been calculated.

Key words: ionic liquid analogous;viscosity, conductivity, density

摘要： 合成了一种无色、透明、均一的氯化胆碱-尿素-氯化镁类离子液体。采用傅里叶红外光谱仪初步解析了类离子液体的结构。利用电导率仪、旋转式黏度计和密度计等仪器分别测定了该类离子液体的电导率、黏度和密度，并得出了其随温度和组成的变化关系。根据物理化学性质与温度的关系计算了Gibbs自由能、焓变和熵变等热力学数据。同时测定了类离子液体的循环伏安曲线并分析了其电化学行为。
