The objective was to separate the interaction of the solute with water into the solute-water interaction and the solute-solute interaction in the presence of water. The solubility of benzene, toluene, n-pentane, cyclopentane, cyclohexane, cyclopentene, cyclohexene, 1,4-cyclohexadiene and cycloheptatriene in H2O and D2O were measured using gas-liquid chromatographic techniques over the temperature range of 278 to 318K. The solubility data were used to compute Henry Law constants and from the temperature dependence of the Henry Law constants, the thermodynamic changes associated with the solution process were calculated. These thermodynamic properties were compared for the water and D2O solutions in terms of the transfer of solute from H2O to D2O. Free energies, enthalpies and heat capacities of transfer were determined as a function of temperature. Theoretical interpretations of Henry Law constants in terms of the molecular properties of the solute and solvent were investigated also. (Author)
