Description: This article discusses the correlation of solute partitioning into isooctane from water and from the gas phase based on updated Abraham equations. Abstract: Experimental data have been compiled from the published literature on the partition coefficients of solutes and vapors into isooctane at 298 K. The logarithms of the water-to-isooctane partition coefficients, log P, and gas-to-isooctane 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 to within average deviations of 0.13 log units or less, which corresponds to a percent deviation between the calculated and observed partition coefficient of approximately 30% or less.
