Abstract:
The influence of 10 nonvolatile solutes on boiling point of methanol-tetrahydrofuran azeotrope was determined by means of isobaric vapor-liquid equilibrium experiments. Based on classical thermodynamics a conclusion of universal significance was derived, i. e. , a little nonvolatile solute always causes the elevation of azeotrope's boiling point irrespective of the variation of its vapor composition. It is in agreement with the experimental results and the relevant reports in the literature without exception.

非挥发性溶质对共沸物沸点的影响
孙仁义*,孙茜
摘要:
测定了10种非挥发性溶质对甲醇-四氢呋喃共沸物沸点的影响.发现与共沸物平衡的气相组成因非挥发性溶质不同发生了不同的变化,但所有非挥发性溶质都引起共沸物沸点升高.运用热力学原理对实验结果进行了讨论.理论分析及对分析结果的实验检验表明,少量非挥发性溶质总引起共沸物沸点升高是一个具有普遍意义的结论.
