Classification of the solvent properties of common liquids

Solubility data reported by Rohrschneider for 82 solvents and several test solutes have been transformed into a corresponding set of solvent characterization parameters: P′, xc, xd and xn values. These latter parameters are approximately corrected for dispersion interactions and for molecular weight effects, and allow the separate characterization of solvent strength (polarity) and selectivity in liquid-liquid chromatography.
