Abstract

A new solvent polarity scale, the Taft π* scale, is explored for its utility in predicting partition coefficients and solubility parameters of non-hydrogen-bonding, non-aromatic solvents. A function of the dielectric constant of the solvent and the dipole moment and molar volume of the solute is used to obtain a priori estimates of orientation (permanent dipole-permanent dipole) solubility parameters. The correlation coefficient between measured and predicted orientation solubility parameters is 0.97; the slope is close to unity.
