摘要：

Activity coefficients at infinite dilution gamma(i)(infinity) of the linear and branched C-1 to C-6 alcohols, acetone, acetonitrile, ethylacetate, alkylethers, and chloromethanes in the ionic liquid 4-methyl-N-butyl-pyridinium tetrafluoroborate (C10H16BF4N) were determined by gas chromatography using the ionic liquid as the stationary phase. The measurements were carried out at different temperatures between 313.1 K and 363.1 K. From the temperature dependence of the limiting activity coefficients partial molar excess enthalpies at infinite dilution H-i(E,infinity) of these polar solutes in the ionic liquid have been derived.
