摘要

本文采用Otsuki-Williams式汽液平衡釜测定了甲酸-乙酸-水体系及甲酸-乙酸-水-醋酸钠体系在98.66kPa下汽液平衡数据.醋酸钠的浓度为1mol/kg溶剂.结果表明

醋酸钠不仅对体系起化学作用

也起物理化学作用.它涉及到了盐溶、盐析和盐效应的不规则现象.

Abstract

Vapour-liquid equilibrium data(VLE) were measured in a Otsuki-Williams still at 9.866×104Pa.Analyses were made for the Ternary system HCOOH-CH3COOH-H2O and the quaternary system HCOOH-CH3COOH-H2O-NaAc in VLE(1mol/(kg solv. ))of NnAc was used. The results show that the favorable effect of NaAc is reflected not only in the chemical action

but also in the physicochemical aspect. This apparently is related to the phenomena of salting out

salting in and their anomalous behavior.
