Vapor-Liquid Equilibria of Hexane-Acetic Acid System and Hexane-Ethanol System Containing a Minute Amount of Water

Abstract

Vapor-liquid equilibria of hexane-acetic acid system and hexane-ethanol system containing a minute amount of water were measured at atmospheric pressure by use of an Othmer-type still in a dry box. It was shown that the equilibrium ratio curve and the activity coefficient curve of the trace component (water) display an unusual and specific shape in each system.
