Experimental data have been compiled from the published chemical and engineering literature pertaining to the infinite dilution activity coefficients, gas solubilities and chromatographic retention factors for solutes dissolved in ionic liquid (IL) solvents. Included in the compilation are chromatographic retention factors for forty-five solutes on a 1-butyl-1-methylpyrrolidinium tricyanomethanide ionic liquid gas-liquid chromatographic stationary phase. The published experimental data were converted to gas-to-IL and water-to-IL partition coefficients, and correlated with the ion-specific equation coefficient version of the Abraham general solvation 2 model. Ion-specific equation coefficients were calculated for 40 different cations and 16 different anions. The calculated ion-specific equation coefficients describe the experimental gas-to-IL and water-to-IL partition coefficient data to within 0.123 and 0.149 log units, respectively.
