Partition of an organophosphorus compound, dichlorvos, between liquid and liquid crystalline phases

The partition coefficients for an organophosphorus compound, dichlorvos (2,2-dichlorovinyl dimethyl phosphate), between pure liquids, micellar solutions, and liquid crystalline phases were determined by spectrometric analysis of the dichlorvos content after equilibration and separation of the phases. The results demonstrated the pronounced importance of associated colloid structures on the partition coefficient and showed that the partition coefficient did not display a simple concentration dependence.
