Abstract
Data have been compiled from the published literature on the partition coefficients of solutes and
vapors into anhydrous sulfolane. The logarithms of the water-to-sulfolane partition coefficients,
log P, and gas-to-sulfolane partition coefficients, log K, were correlated with the Abraham
solvation parameter model. The derived correlations described the observed log P and log K
values for solutes dissolved in sulfolane to within average standard deviations of 0.14 log units
or less. The log P correlation was extended to include the partition of ions by inclusion of a
cation-solvent and an anion-solvent term.
