Expanding the Equilibrium Solubility and Dissolution Thermodynamics of Benzoic Acid in Aqueous Alcoholic Mixtures

The equilibrium solubility of benzoic acid in water and ethanol, as well nine {ethanol (1) + (2)} mixtures, was determined from T = (293.15 to 323.15) K. Benzoic mole fraction these aqueous-ethanolic mixtures adequately correlated with some well-known correlation/prediction models, obtaining mean percentage deviations 2.2 7.6%. Apparent thermodynamic quantities, namely, Gibbs energy, enthalpy, entropy, for the dissolution, mixing solvation processes, were computed by means van ’t Hoff equations. enthalpy–entropy compensation plot apparent enthalpy vs. energy dissolution not linear, indicating entropy mechanisms transfer. Ultimately, using inverse Kirkwood–Buff integrals, it is observed that preferentially solvated molecules water-rich but ethanol those 0.24 < x1 1.00.
