ABSTRACT

Activity coefficients at infinite dilution Ai have been measured for 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-butyl-3-methylimidazolium trifluoromethanesulfonate ([BMIM][CF3SO3]) 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 Ai values.
