Molal solubility, dissociation, association and solvation parameters for saturated benzoic acid solutions in various solvents at 298.15 K

摘要

The molal solubilities for saturated solutions of benzoic acid at 298.15 K in various solvents were determined. The solvents used are: water, ethanol, dimethylsulphoxide, acetonitrile, methanol, hexamethylphosphortriamide, 1,4-dioxane and N,N-dimethylformamide. From the experimental data for solubilities, pH and densities, the different volumes, free energies, dissociation constants, association constants and solvation parameters were estimated. The results are also discussed in this article.
