ABSTRACT
The activity coefficients at infinite dilution of 22 organic solutes in the ionic liquid ethyl(2-hydroxyethyl)dimethyl-ammonium diethylphosphate have been determined using gas-liquid chromatography at the temperatures ranging from 323.15 to 363.15 K. The partial molar excess enthalpies at infinite dilution of the solutes in the ionic liquid were calculated from the temperature dependence of the experimental activity coefficient at infinite dilution values. The selectivity for the hexane/benzene and cyclohexane/benzene separation problems were also derived from activity coefficients at infinite dilution and compared to the literature values for other ionic liquids and N-methyl-2-pyrrolidone.
