双液系气液平衡相图实验的改进与优化
Improvement and Optimization of the Experiment on Gas-Liquid Equilibrium Phase Diagram of Binary Liquid Systems
摘要
Abstract
In response to the limitations inherent in the conventional experimental teaching of vapor-liquid equilibrium phase diagrams for bina-ry liquid systems,this study investigates the impact of incorporating magnetic stirring on both the phase diagram determination and the time re-quired to establish vapor-liquid equilibrium in the ethanol-cyclohexane system.The results demonstrate that activation of the magnetic stirring function significantly reduces the time needed to achieve vapor-liquid equilibrium and enhances the accuracy of boiling point measurements.Consequently,the overall effectiveness of the experimental teaching and the reliability of the collected data are notably improved.关键词
