The activity coefficients at infinite dilution, gamma(infinity), gas-liquid partition coefficients, K-L, the partial molar excess Gibbs free energy Delta G(1)(E,infinity), enthalpy Delta H-1(E,infinity) and entropy Delta S-1(E,infinity) at infinite dilution for 61 organic solutes and water in the ionic liquid 1-(2-methoxyethyl)-1-methylpyrrolidinium bis(trifluoromethylsulfonyl)-amide were determined by inverse gas chromatography at the temperatures from (318.15 to 368.15) K. The values of the selectivity for selected compounds which form azeotropic mixtures were calculated from the gamma(infinity) and compared to the literature values for other ionic liquids based on bis(trifluoromethylsulfonyl)-amide anion.
