THE PROPERTIES OF ORGANIC LIQUIDS THAT ARE RELEVANT TO THEIR USE AS SOLVATING SOLVENTS

The solvation properties of solvents (solvent effects) depend mainly on their polarity/polarizability (accounting also for dispersion interactions), hydrogen bond donation and acceptance abilities, and cohesive energy density, that are orthogonal to each other. These are best measured by the Kamlet-Taft solvatochromic parameters pi*, alpha, and beta and the square of Hildebrand's solubility parameter, delta(H)2, respectively. The first three are presented for a large set of solvents, together with several other solvation indices that are correlated with them.
