Abstract: Tri-n-butyl-phosphate (TBP) is one of the important extractants and widely used in solvent extraction of chemical industry. But the thermodynamic properties of molecular interaction between water and TBP is an unsolved question in the extraction process. In this paper, association constant K_c of water and TBP, ΔG° of the association reaction have been studied by means of dielectric polarization measurement. The limiting values of molecular polarizability and dipole moments of TBP and TBP. H_2O in benzene have also been obtained.
