摘要
该文在单组分气液平衡测定仪的基础上设计了一个简便的多组分气液平衡测定装置。测定了283.2～313.2K下苯-氯仿体系的饱和蒸气压,并应用Barker的数值方法对实验数据进行了计算机处理,求得了298.2K下体系的组分活度系数与过量热力学函数。最后对实验结果及装置的可靠性进行了简要讨论。
After developing the current apparatus measuring pres-sure of pure substance, this work is a determination of the pressurefor the benzen-chloroform mixtures at 283.2～313.2 K. By using theBarker's method in the data treatment process, the component activitycoefficients and the excess thermodynamic functions of the mixtures at298.2K are evaluated. A short discussion about the results and the ap-paratus is given.
