Investigation of Complex Reaction Between Extractant Molecules by Dielectric Measurements

The molecular dipole moment, as a very useful parameter for structural studies, has been applied to study the intermolecular interaction, such as association reaction, etc., between two extractants or extractant and extraction complex.The molar polarizabilities P and dipole moments n of some important extractants containing phosphorus TBP, TOPO, TBPO, P204, DBP, HDiAP, DiAEP in benzene were determined by use of dielectric measurements. These results are summarized in Table 1.Molecular-interaction between acidic and neutral extractants containing phosphorus has been studied by the same method. These formation constants Kc, molar polarizabilities P and dipole moments n of complexes are shown in Table 2.Dielectric property of mixed solution can be applied to the study of synergistic extraction systems.
