Gas liquid chromatography was employed to measure the activity coefficients of a group of hydrocarbons at infinite dilution in tri-n-octyltin chloride at 40, 45, 50, 55 and 60°C. The partial molar excess thermodynamic quantities are interpreted by means of the Flory-Patterson theory, and compared with the results obtained for the same group of solutes in tetra-n-octyltin as the solvent. The alkanes activity coefficients and excess enthalpies in both phases are linearly related. Enthalpyentropy compensation in both solvents is discussed.
