CORRELATION OF PARTITION-COEFFICIENTS FOR POLAR AROMATIC AND ALIPHATIC MOLECULES BETWEEN TRIMETHYLDODECYLAMMONIUM BROMIDE MICELLES + WATER AND OCTANOL + WATER-SYSTEMS AT 298.15-K

The partition coefficient P of aromatic molecules with various polar moieties has been determined in aqueous trimethyldodecylammonium bromide (DOTMABr) micellar solutions. The P value of perfluorobutanol (PFB) in aqueous anionic and cationic, hydrogenated and perfluorated surfactant solutions was also measured. It is shown that the linear correlation found recently between log P values of polar aliphatic molecules in the DOTMABr plus water and in the octanol plus water systems holds also for polar aromatic molecules with nitrile, ketone and aldehyde groups as well as for PFB. The correlation does not hold for polar aromatic molecules with hydrogen bond acceptor and donor properties.
