The activity coefficients at infinite dilution, γ13∞ and gas–liquid partition coefficients, KL for 62 solutes: alkanes, alkenes, alkynes, cycloalkanes, aromatic hydrocarbons, alcohols, thiophene, ethers, ketones, esters, 1-nitropropane, butanal, acetonitrile, acetic acid and water in the ionic liquid 4-(2-methoxyethyl)-4-methylmorpholinium bis(trifluoromethylsulfonyl)-amide were determined by gas–liquid chromatography at the temperatures from (318.15 to 368.15) K. The partial molar excess Gibbs free energies ΔG1E,∞, enthalpies ΔH1E,∞ and entropies ΔS1E,∞ at infinite dilution were calculated from the experimental γ13∞ values obtained over the temperature range. The selectivities for selected compounds which form azeotropic mixtures were calculated from the γ13∞ and compared to the literature values for other ionic liquids based on bis(trifluoromethylsulfonyl)-amide anion.
