Implication

Molecular simulation study demonstrates accurate prediction of partition coefficients in environmental pollutants, suggesting computational methods can reliably evaluate chemical fate.

Key Points

To establish and evaluate a molecular simulation methodology for predicting n-hexane/water and 1-octanol/water partition coefficients of environmentally hazardous organic pollutants.
Modeled substituted alkyl-aromatic molecules, chlorobenzenes, polychlorinated biphenyls (PCBs), and polychlorinated diphenyl ethers (PCDEs).
Calculated absolute solvation Gibbs energies in aqueous and organic solvent phases using molecular dynamics simulations paired with thermodynamic integration.
Achieved an average absolute deviation of 0.4 log P units compared to experimental measurements across the tested compounds.
Successfully predicted partition coefficients across distinct solvent pairs based entirely on physical principles without requiring a priori experimental data.
