SummaryWater solubility (Sw) and log Kow values have been determined for 154 possible polychlorobiphenyls using the retention indices obtained by RP-HPLC and structurally selected PCB congeners with known log Kow values for the regression lines. The water solubility data are melting point corrected. 
Prediction of aqueous solubility and octanol—water partition coefficient for pesticides based on their molecular structure
Abstract Correlations have been derived for the estimation of aqueous solubilities and octanol—water partition coefficients for pesticides, based solely on their molecular structure. The parameters
Retention-index based vapor pressure estimation for polychlorobiphenyl (PCB) by gas chromatography
SummaryVapor pressures for 133 individual polychlorobiphenyl congeners as subcooled liquids were determined by two different approaches on the basis of gas-chromatographic retention indices obtained
Correlation of aqueous solubility and octanol-water partition coefficient based on molecular structure
Abstract Correlations have been proposed for prediction of aqueous solubility and octanol-water partition coefficients for halogenated benzenes, polycyclic aromatic hydrocarbons and polychlorinated
High-resolution gas chromatography retention data as a basis for estimation of the octanol–water distribution coefficients (Kow) of PCB: the effect of experimental conditions
The semi-experimental approach to approximating physicochemical data relevant to environmental distribution by correlation with gas chromatography (GC) retention data has been extended to the determination of Kow values.
Solubility and micelle-water partitioning of polychlorinated biphenyls in solutions of bile salt micelles.
The partitioning behavior of the pertinent extremely hydrophobics between the aqueous and micellar phases is not completely comparable with simple organic solvent/water systems and the correlation between log Kow and log Kmw is non-linear.
Application of different RP-HPLC methods for the determination of the octanol/water partition coefficient of selected tetrachlorobenzyltoluenes.
Reversed-phase high-performance liquid chromatography (RP-HPLC) in both, isocratic and gradient elution mode was used for a renewed determination of octanol/water partition coefficients (Kow) of selected tetrachlorobenzyltoluene (TCBT) isomers, identifying this substance class as very hydrophobic but the data are relatively inconsistent.
Physico-chemical characteristics and quantitative structure-activity relationships of PCBs
The polychlorinated biphenyls (PCBs) comprise a group of 209 congeners varying in the number of chlorine atoms and substitution patterns. These compounds tend to be biomagnified in foodwebs and hav
n-Octanol-water partition coefficients, aqueous solubilities and Henry's law constants of fatty acid esters
Abstract The aqueous solubility and n-octanol-water partition coefficient of fifteen fatty acid esters are determined by the RP-HPLC method. Aqueous solubilities decrease from 5.7 × 10 −5 M for
Estimation of vapor pressures, solubilities and Henry's law constants of selected persistent organic pollutants as functions of temperature
Abstract An internally consistent set of temperature dependent physical-chemical property data was derived for 73 persistent organic pollutants, including polychlorinated biphenyls, diphenylethers,
Application of the characteristic root index model to the estimation of N-octanol/water partition coefficients. polychlorinated biphenyls
Abstract The ability of the Characteristic Root Index (CRI) to predict the n-octanol/water partition coefficients (K ow ) of polychlorinated biphenyls (PCBs) has been demonstrated. The CRI for 58


Estimation of the aqueous solubility of some aromatic compounds
The aqueous solubility of an organic compound can often be the major factor which controls its bioaccumulation. Many environmentally important compounds are not taken up into the food chain because
