The Hildebrand solubility parameters of ionic liquids-Part 2

Abstract

The Hildebrand solubility parameters have been calculated for eight ionic liquids. Retention data from the inverse gas chromatography measurements of the activity coefficients at infinite dilution were used for the calculation. From the solubility parameters, the enthalpies of vaporization of ionic liquids were estimated. Results are compared with solubility parameters estimated by different methods. © 2011 by the authors; licensee MDPI, Basel, Switzerland.
