Notes

Abstract: The Abraham solvation parameter model is used to calculate the numerical values of the solute descriptors for 3-chlorobenzoic acid from experimental solubilities in organic solvents. The mathematical correlations take the form of
log(Cs/Cw)= c + e·E + s·S + a·A + b·B + v·V
log(Cs/Cg)= c + e·E + s·S + a·A + b·B + l·L
where Cs and Cw refer to the solute solubility in the organic solvent and water, respectively, Cg is a gas phase concentration, E is the solute excess molar refraction, V is the McGowan volume of the solute, A and B are measures of the solute hydrogen-bond acidity and hydrogen-bond basicity, S denotes the solute dipolarity/polarizability descriptor, and L is the logarithm of the solute gas phase dimensionless Ostwald partition coefficient into hexadecane at 298K. The remaining symbols in the above expressions are known solvent coefficients, which have been determined previously for a large number of gas/solvent and water/solvent systems. The Abraham solvation parameter model was found to describe the experimental solubility data and published literature partitioning data of 3-chlorobenzoic acid to within an overall standard deviation of 0.083 log units.
