Activity Coefficients at Infinite Dilution of Organic Compounds in 1-Butyl-3-methylimidazolium Tetrafluoroborate Using Inverse Gas Chromatography

Résumé

Activity coefficients at infinite dilution (γ∞) of organic compounds in the room-temperature ionic liquid 1-butyl-3-methylimidazolium tetrafluoroborate were determined using inverse gas chromatography from (303.35 to 332.55) K. Retention data were used to estimate the influence of gas−liquid and gas−solid interfacial adsorption on the value of activity coefficients at infinite dilution of solutes in this ionic liquid. Most of the polar solutes were retained largely by partition, while n-alkanes were retained predominantly by interfacial adsorption on the ionic liquid studied. The solvation characteristics of the ionic liquid were evaluated using the Abraham solvation parameter model.
