ABSTRACT
Abstract An ionic liquid (IL) BMIZnCl3 has been synthesized by directly mixing zinc chloride (ZnCl2) and 1-butyl-3-methylimidazolium chloride (BMIC) with molar ratio 1/1 under a dry argon atmosphere. The density and surface tension of the IL in temperature range from 313.2 K to 343.2 K were determined. The value of thermal expansion coefficient and surface entropy were estimated by extrapolation. In terms of Glasser s theory, the standard molar entropy and lattice energy of the IL were estimated. Using the methods of Kabo and Rebelo, the molar enthalpy of vaporization of the IL, at T = 298 K and at the hypothetical normal boiling point were estimated. The thermal expansion coefficient, a, calculated by the interstice model is of the same order of magnitude as the experimental value
