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
The influence of ten kinds of non-volatile solutes on the boiling point of methanol-tetrahydrofuran azeotrope was determined. The gas phase composition in equilibrium with azeotrope was found to vary in different non-volatile solutes, but all of the non-volatile solutes caused azeotropes Boiling point increased. The experimental results are discussed using the principle of thermodynamics.The theoretical analysis and experimental analysis of the analytical results show that it is a general conclusion that a small amount of non-volatile solute always causes the boiling point of the azeotrope to rise
