Abstract
Infinite dilution activity coefficients and gas-to-liquid partition coefficients are reported for 47 and 45 organic probe molecules dissolved in 1-hexylquinuclidinium bis(trifluoromethylsulfonyl)imide ([Quin6]+[Tf2N]â) and 1-octylquinuclidinium bis(trifluoromethylsulfonyl)imide ([Quin8]+[Tf2N]â), respectively, as determined by inverse gas chromatography in the temperature range of 313Â K to 353Â K. The measured partition coefficient data were converted to water-to-liquid partition coefficients using standard thermodynamic relationships and published gas-to-water partition coefficient data. Both sets of calculated partition coefficient data for each ionic liquid solvent were analyzed in terms of the Abraham general solvation model. Mathematical correlations derived from the Abraham model described the measured partition coefficient data to within 0.14 or fewer log units.
