Abraham model correlations for solute partitioning into o-xylene, m-xylene and p-xylene from both water and the gas phase

Experimental data have been compiled from the published literature on the partition coefficients of solutes and vapors into o-xylene, m-xylene and p-xylene at 298 K. The logarithms of the water-to-xylene partition coefficients, log P, and gas-to-xylene partition coefficients, log K, were correlated with the Abraham solvation parameter model. The derived mathematical expressions described the observed log P and log K data for the three xylene isomers to within average deviations of 0.14 log units or less.

► Gas-to-o-xylene and water-to-o-xylene partition coefficient data compiled for 59 solutes. ► Gas-to-m-xylene and water-to-m-xylene partition coefficient data compiled for 79 solutes. ► Gas-to-p-xylene and water-to-p-xylene partition coefficient data compiled for 91 solutes. ► Experimental partition coefficient data correlated using the Abraham solvation parameter model. ► Derived Abraham model correlations describe the observed data to within 0.14 log units.
