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
