Abstract |
|
|
|
Literature data regarding partitioning of compounds from the gas phase to alkanes and from water to alkanes have been compiled and analyzed in accord with the Abraham solvation parameter model. Mathematical correlations have been developed for describing the partitioning behavior of organic solutes and gases into hexane, heptane, octane and decane. Derived mathematical expressions were found to predict the available partition coefficient data to within 0.15 log units or better.
