摘要: 采用Otsuiki-Williams式汽液平衡仪在9.866×104Pa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。

Abstract: Using the apparatus--the Otsuiki-Williams still, the vapor-liquid equilibrium data for the systems of formic acid-water, acetic acid-water, formic acid-acetic acid, formic acid-acetic acidwater with and without salt were measured, respectively. Isobaric vapor-liquid equilibrium phase diagrams at the pressure of 9.866×104 Pa for these systems are ploted. The results obtained show the salt effect is obvious in all cases.

Key words: Vapor-liquid equilibrium, Salt effect, Formic acid-acetic acid-water system
