摘　　要：本文利用量热滴定的方法,研究了萃取有机相中酸性萃取剂P204、P507、P272和PMBP与中性磷酸酯之间的缔合作用,求出相应的缔合常数β以及热力学函数△H、△S、△G。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.
