“…B ii and B i 2 can be inferred from the basic parameters P c ij , T c ij , v c ij , Z c ij , and eccentricity factor ω ij in the literature equations. The eccentricity factors ω of the solutes and carrier gas, the saturated vapor pressure of solutes ( i ) in the temperature range of 313 to 353 K, and the critical parameters ( T c , P c , Z c , V c ) were obtained from the calculation data of Ge and co-workers. − …”

Infinite dilution activity coefficients (γ i ∞) of 31 organic solutes (alkanes, cycloalkanes, olefins, aromatics, chlorinated alkanes, alcohols, and other polar organic solutes) in the ionic liquid (IL) 1-butyl-2,3-dimethylimidazole thiocyanate ([BMMIM][SCN]) were determined by gas–liquid chromatographic (GLC) method in the temperature range of 313.15–353.15 K. The infinite dilution partial molar excess enthalpies (H̅ i E, ∞), entropies (T ref S̅ i E, ∞), and Gibbs free energies (G̅ i E, ∞) of the organic solutes at the reference temperature T = 298.15 K and the solubility parameters (δ3) of [BMMIM][SCN] were derived from γ i ∞. The gas–liquid partition coefficients (K L) of solutes at different temperatures were calculated by referring to the densities of [BMMIM][SCN]. The linear free energy relationship solvation model was used to fit the K L values, and the K L prediction model was obtained. The selectivity (S ij ∞) and capacity (k j ∞) of n-hexane (i)/benzene (j) and cyclohexane (i)/benzene (j) at infinite dilution at 323.15 K were calculated. The results were compared with the values of ILs with the thiocyanate anion in the literature.
