Abstract:

Activity coefficients at infinite dilution ci yen of alkanes, alkenes, and alkylbenzenes as well as of the linear and branched C1-C6 alcohols, acetone, acetonitrile, ethyl acetate, alkyl ethers, and chloromethanes in the ionic liquids 1-methyl-3-ethyl-imidazolium bis(trifluoromethyl-sulfonyl) amide and 1,2-dimethyl-3- ethyl-imidazolium bis(trifluoromethyl-sulfonyl) amide were determined by gas chromatography using the ionic liquids as the stationary phase. The measurements were carried out at different temperatures between 313 K and 363 K. From the temperature dependence of the limiting activity coefficients partial molar excess enthalpies at infinite dilution Hi E,yen of the solutes in the ionic liquids have been derived.
