The Hildebrand’s solubility parameters have been calculated for 18 ionic liquids from the inverse gas chromatography measurements of the activity coefficients at infinite dilution. Retention data were used for the calculation. The solubility parameters are helpful for the prediction of the solubility in the binary solvent mixtures. From the solubility parameters, the standard enthalpies of vaporization of ionic liquids were estimated.
Keywords: ionic liquid; Hildebrand’s solubility parameter; standard enthalpy of vaporization ionic liquid; Hildebrand’s solubility parameter; standard enthalpy of vaporization
