无限稀活度系数的推算

Prediction of Activity Coefficients at Inifinite Dilution

应用ＵＮＩＦＡＣ模型导出了甲醇氯苯和苯正丙醇体系各组元的无限稀活度系数的计算式．由此回归的Ｗｉｌｓｏｎ或ＮＲＴＬ参数预测的活度系数值与根据气液平衡实验获得的结果符合良好．

In this paper,two formulas for calculating the infinite dilution activity coefficients of components in the system methanolchlorobenzene and benzenenpropanol are presented by means of UNIFAC models respectively. Prediction of the activity coefficients with Wilson or NRTL parmeters regressed by the formulas agrees well with that obtained for the VLE experiment.
