PHYSICO-CHEMICAL PROPERTIES OF MAGNESIUM IONIC LIQUID ANALOGOUS

In this paper, the solubility of Choline chloride (ChCl) in ethylene glycol (EG) was measured by isothermal method in the temperature range between 0°C and 120°C. The solubility of MgCl2 in saturated ChCl-EG mixture was measured by isothermal method at 20°C, 50°C and 70°C, respectively. Ionic liquid analogous containing MgCl2 was prepared based on the measured solubility data. The structure of the ionic liquid analogous is preliminarily investigated by Fourier transform infrared spectroscopy. The physical and electrochemical properties of the ionic liquid such as viscosity, conductivity, molar conductivity and density were measured as function of temperature and compositions. It was found that magnesium ionic liquid analogous was highly conducting and low viscosity. The ChCl and MgCl2 had a great effect on the studied properties.
