采用Otsuiki-Williams式汽液平衡仪在9.866×10~4Pa下测定了甲酸-水、乙酸-水、甲酸-乙酸、甲酸-乙酸-水体系无盐和加氯化镁后各体系的汽液平衡数据,绘制了两组分和三组分体系相图。相图表明氯化镁有明显的盐效应。
Vapor-liquid equilibrium data of each system of formic acid-water, acetic acid-water, formic acid-acetic acid, formic acid-acetic acid-water system without salt and magnesium chloride were measured by Otsuiki-Williams vapor-liquid equilibrium instrument under 9.866 × 10 ~ Draw two-component and three-component system phase diagram. Phase diagram shows that magnesium chloride has obvious salt effect.
