Summary

The partial molar free energies at infinite dilution are determined at 25°C by using gas-liquid chromatography. The stationary phase liquids are benzene, toluene, chlorobenzene, benzonitrile, N,N-dimethylacetamide, N,N-dimethylformamide, and dimethyl sulfoxide. The solutes are n-alkanes of ethane to n-heptane, ethyl chloride, bromide and iodide, and propionitrile. When the solvent becomes polar, the values for the n-alkane solutes are found to increase, that for the nitrile to decrease, and those for the halides to behave midway. Empirical analyses of the values of the free energies are presented by comparing the results with those in n-hexane.
