Vapor pressures and enthalpies of vaporization of 39 organic compounds were determined. Activity coefficients of organic solutes in 8 binary mixtures with 1-Methyl-3-Ethyl-Imidazolium Bis(trifluoromethyl-sulfonyl) Imide are presented. The results were described with NRTL-model.
А new method of the thermophysical properties (density, capacity, thermal conductivity and viscosity) prediction, using a limited initial information, for the ionic liquids with [nnim]+, [mbpi]+ - cations and NTf2-, BF4-, PF6- - anions was suggested.
Key words: ionic liquids, thermophysical properties, gas-liquid chromatography, transpiration method, NRTL-model, prediction.
