摘要：
A method for prediction of the solubility of sulfonamides in water and in some organic solvents based on the modified Hildebrand-Scatchard equation for regular solutions is described. Introduction into the equation of the dielectric constant or solvatochromic polarity parameter of the solvent allows the applicability of regular solution theory to be extended to polar systems which are widely employed in pharmaceutical practice. The predicted solubilities of 14 sulfonamides in water at various temperatures and of eight sulfonamides in organic solvents of different polarity were compared with those determined experimentally.
