Abstract
Abraham descriptors for 40 phthalate esters have been calculated from a variety of experimental data, including water-solvent partition coefficients, high performance liquid chromatographic and gas chromatographic retention times. These descriptors can then be used to calculate a large number of physicochemical and biochemical properties of the esters; values are given for dinonyl phthalate as an example. Once the Abraham descriptors have been obtained for a given phthalate ester, no more than simple arithmetic is needed to calculate values of a huge range of properties. The 'three solubility method' yields data that are consistent for a particular physicochemical property, but not necessarily correct data. Previous literature values for air-water partition coefficients for the higher phthalates are likely to be incorrect by several orders of magnitude.
