Abstract

Questions are raised regarding whether or not the curve-fit equation coefficients reported by He and cowokers for the Kamlet and Taft linear solvent energy relationship model are meaningful. One of the calculated coefficients suggests that the solubility of 2-nitro-3-methylbenzoic acid decreases with increasing hydrogen-bond acidity of the solvent. The Abraham general solvation parameter model is suggested as a better model for obtaining information regarding molecular interactions between 2-nitro-3-methylbenzoic acid and surrounding solvent molecules.
