| Abstract: | In this paper, the association reaction between acid extractrants P204, P507, P272, PMBP and neutral phosphated extractants TOPO, DAMP, TBP in benzene have been studied by the titration calorimetry method. The associate constants and thermodynamic functions of the interactions are determined through data fitting. Comparing with other methods, this one is easier to be carried out and gives more accurate results. |
