摘　　要：利用双循环气液平衡釜测定了101.3 kPa下正丁基硫醇-正辛烷体系的气液平衡数据,并运用该实验结果,进一步获得组分的液相活度系数。实验数据经Herrington方法检验符合热力学一致性。用UNIQUAC热力学模型对该实验数据进行处理,计算结果与实验值的平均绝对偏差为0.050 5。Isobaric vapor-liquid equilibrium under 101.3 kPa for the system of n-butyl mercaptan and octane was measured by a vapor-liquid equilibrium autoclave. The activity coefficients of the system were determined further. Vapor liquid equilibrium data for the binary system passed the thermodynamic consistency check. The activity coefficients were correlated with the UNIQUAC model, and the results were in perfect agreement with the experimental values. The average deviation was about 0.050 5.
