摘要： 如何计算与测量多组元体系的活度系数,是一个重要问题。我们的工作是选取了磷酸三丁酯(TBP)与硫国酰基三氟丙酮(TTA)溶于苯的体系,进行了实验测量与理论计算,理论与实验取得了基本一致的结果。

Abstract: For the investigation of the binary synergic extracting regularity, a multico-mponent system TBP-TTA-C6H6were studied. The activity coefficients of benzene and tributylphosphate (TBP) were measured by vapour pressure and 32P-labeled TBPdistribution method respectively, then the activity coefficient of thenoyltri-fluroacetone (TTA) was obtained by Gibbs-Duhem equation. The activity coefficient of benzene, which dissolved two solutes-TBP and TTA simultaneously, have been also calculated by statistical theory using cluster expension method. The result is consistent with experimental data in the region of mole fraction of benzene greater than 0.6.
