本文是利用自制的简易恒压沸点仪研究丙酮-氯仿体系的平衡相图。通过本实验,可使学生学习和掌握简易的恒压控制技术,本实验还找出了恒沸点,恒沸混合物组成与压力的关系。应用其中恒沸点与压力的关系式算出的结果,可以作为衡量学生在常压条件下所得实验结果的标准。双液系的气液平衡相图实验是物理化学验的基本内容之一,通常是用沸点仪在常压条
This article is the use of home-made simple constant pressure boiling point of acetone - chloroform equilibrium system phase diagram. Through this experiment, students can learn and master simple constant pressure control technology, this experiment also found a constant boiling point, azeotropic mixture composition and pressure relationship. Using the relationship between the constant boiling point and the pressure calculated results can be used as a measure of the students under normal pressure conditions obtained experimental results of the standard. The double-liquid system gas-liquid equilibrium phase diagram experiment is one of the basic contents of physical and chemical tests, usually using the boiling point meter in atmospheric pressure
