Activity Coefficients at Infinite Dilution of Organic Compounds in Trihexyl(tetradecyl)phosphonium Bis(trifluoromethylsulfonyl)imide Using Inverse Gas Chromatography

摘要

Activity coefficients at infinite dilution γ~∞ of organic compounds in the ionic liquid (IL) trihexyl(tetrade-cyl)phosphonium bis(trifluoromefhylsulfonyl)imide were determined using inverse gas chromatography at three temperatures, T= (302.45, 322.35, and 342.45) K. Linear free energy relationship (LFER) correlations have been obtained for describing the gas-to-IL and water-to-IL partition coefficients.
