Abstract

We propose and test an efficient approach for the assessment of the enthalpies of vaporization of ionic liquids at the reference temperature 298.15 K. The approach is based on activity coefficients at infinite dilution of volatile organic solutes in ionic liquids bearing the imidazolium cation of the general formula [C_nmim][Anion].

Keywords: enthalpy of vaporization; infinite dilution activity coefficient; ionic liquids; thermodynamics.
