Abstract
Abstract In this article solubility of succinic acid (SA) were measured by the gravimetric method in pure water and in different composition of binary mixtures of water and ethanol solvents mixtures at 288.15 K to 308.15 K. The solubility data were taken for estimating the standard transfer Gibbs energies ΔGt0(i), enthalpy ΔHt0(i) and entropy of transfer ΔSt0(i) of succinic acid in aqueous-ethanol solution. The chemical contributions of free energies (ΔGt , ch0(i)) and entropies (ΤΔSt , ch0(i)) of transfer of succinic acid have been computed by subtracting the cavity effects and dipole-dipole interaction effects from the total transfer energies. The solubility data and other physicochemical properties of succinic acid in aqueous-ethanol solvent mixtures are essential for biochemistry, particularly in the food, cosmetic, pharmaceutical sciences, industrial design and further theoretical studies. Therefore the characteristics of the solvation thermodynamics of succinic acid in aqueous-ethanol mixed solvent systems were discussed in this article.
