Models for calculating solubility in binary solvent systems

Abstract

Two empirical models which express the relationship between the solute solubility and the concentration of one of the solvents in a binary solvent system are presented. The proposed models have been compared with previous similar models similar either in their original or modified forms from accuracy and predictability points of view using many experimental data taken from the literature. Both models were in some respects superior to the original and modified forms of the previous models. The modification of some of the previous models has improved the accuracy of the original models.
