摘要： 以盐湖副产物六水氯化镁为原料,合成一种无色、透明、均一的含六水氯化镁类离子液体。通过傅里叶红外光谱仪初步确定了含六水氯化镁类离子液体中存在的氢键种类。利用电导率仪、数字式黏度计和密度仪分别测定含六水氯化镁类离子液体的黏度、密度和电导率,对类离子液体的物理化学性质和温度、组成关系进行拟合,获得其随温度和组成的变化规律。根据黏度、电导率、密度和温度之间的相互关系计算了吉布斯自由能(ΔG*)、焓变(ΔH*)和熵变(ΔS*)等热力学数据。

Abstract: In this paper, a colorless, transparent and homogeneous ionic liquid containing hexahydrate magnesium chloride was synthesized by using the byproduct of hexahydrate magnesium chloride from Saline Lake. The hydrogen bonding types in the hexahydrate magnesium chloride ionic liquid were determined by means of the Fourier transform infrared spectrometer. The viscosity, density and conductivity of the ionic liquid were measured respectively by using conductivity meter, digital viscometer and densimeter. The change rule of physicochemical properties of the ionic liquid was established with the variation of temperature and its composition. Furthermore the Gibbs free energy (G*), enthalpy (H*), entropy (S*) and other thermodynamic data were calculated based on the relation of viscosity, conductivity, density and temperature.

Key words: ionic liquid, six water magnesium chloride, physical and chemical properties, thermodynamic data
