Title:

Activity Coefficients at Infinite Dilution of Polar Solutes in 1-Propyl-2,3-dimethylimidazolium Tetrafluoroborate Using Gas Liquid Chromatography

Keywords:

Abstract:

Activity coefficients at infinite dilution Ai of 17 polar solutes (linear and branched C1 to C5 alcohols, acetonitrile, acetone, 1,4-dioxane, tetrahydrofuran, ethyl acetate, and chloromethanes) in the ionic liquid 1-propyl-2,3-dimethylimidazolium tetrafluoroborate ([PDMIM][BF4]) have been measured by the gas-liquid chromatographic method with the ionic liquid as the stationary phase. The measurements were carried out in the temperature range of (303.15 to 363.15) K. The partial molar excess enthalpies at infinite dilution Hi E, of the solutes in the ionic liquid were also derived from the temperature dependence of the A values.
