In this paper, the dissolution and dissociation enthalpies of benzoic acid in ethanol water and isopropanol-H2O mixtures have been determined by two kinds of microcalorimeters respectively. Combined with the corresponding Gibbs function changes existing in the literature, the dissolution and dissociation entropies have been calculated. Great efforts have been made to interpret the characteristic variations of the transfer enthalpies and entropies according to the skin phase model for solute solvent interactions and the structure alteration of the mixed solvents.
