ABSTRACT

The enthalpies of dilution of (2S,3R,4R,5R)-hexane-1,2,3,4,5,6-hexol in water and aqueous sodium halide solutions have been determined by isothermal flow-mix microcalorimetry at T = (293.15 to 318.15) K. Experiential equations of apparent enthalpies of dilution varying with the concentration of the polylol have been obtained from the experimental data in terms of the improved McMillan-Mayer theory. Enthalpic interaction coefficients, h2, h3, and h4, pairwise entropic interaction coefficient s2, and Gibbs free energy pairwise coefficient g2 have been calculated. The values of pairwise enthalpic interaction coefficient, h2, have been discussed in the light of solute-solute and solute-solvent interactions. The results indicate that the values of h2 show quite well that the straight-line dependence on temperature and pairwise entropic interaction coefficient, s2, is a constant in the experimental range of temperature.
