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。
Based on the single-component gas-liquid equilibrium detector, a simple multi-component gas-liquid equilibrium measurement device is designed. The saturated vapor pressure of the benzene-chloroform system at 283.2 ~ 313.2K was measured. The experimental data were processed by Barker’s numerical method. The activity coefficients and excess thermodynamic functions of the system at 298.2K were obtained. Finally, the experimental results and the reliability of the device are briefly discussed.
