Abstract: In this work, new set of experimental activity coefficients at infinite dilution, γ13∞ for 51 various organic solutes such as alkanes, 1-alkenes, 1-alkynes, cycloalkanes, aromatic hydrocarbons, alcohols, thiophene, ethers, ketones, acetonitrile, pyridine, 1-nitropropane, and water in tributylethylphosphonium diethylphosphate, [P2,4,4,4][DEP] have been measured in temperature range T = (328.15 to 368.15) K by gas–liquid chromatography, GLC. From experimental data the partial molar excess Gibbs free energies ΔG1E,∞, enthalpies ΔH1E,∞, and entropies TrefΔS1E,∞ at infinite dilution were calculated. Additionally the gas–liquid partition coefficients, KL were determined. Moreover, capabilities of the studied ionic liquid in several liquid–liquid extraction processes are evaluated by selectivity and capacity at infinite dilution. These parameters were compared to the values from the recent literature for other ionic liquids with phosphonium cation or diethylphosphate anion. Additionally, basic thermophysical cha...
