Octanol/water partition coefficients (K-ow) of chlorinated paraffins (
CPs) from a commercial mixture ('Cereclor 60L') were determined using
a ''slow-stirring'' method. Log K-ow values for the different congener
groups ranged from 5.85 to 7.14. Equilibrium was reached within a few
days, and K-ow values were the same at two CP-concentrations. A clear
relationship is found between the total number of chlorine and carbon
atoms and log K-ow for the CP-congener groups and a series of smaller
chlorinated alkanes from the literature.
