摘要

本文报导对含碘化物系统汽液平衡的研究结果。在我们所测定的一系列二元系以及一个三元系实验数据的基础上

主要研究了下列两个问题:（1）利用热力学方法

进行了温度、压力、液相与汽相组成间的相互推算。它有助于取得完整的基础数据

并判断数据的热力学一致性。（2）研究了数据的关联以及对多元系的推算。结果表明

虽然碘化氢水溶液是强电解质溶液

利用NRTL方程

并将其参数展开为温度的多项式

仍可满意地关联并准确预测多元系的汽液平衡。

Abstract

This paper reports the results of studying on the vapor liquid equilibrium for the systems containing iodide. Based on the data of a series of binary systems and a ternary system determined by ourselves

we studied the following two problems

(a )Among the four variables

temperature

pressure

liquid and vapor compositions

we were able to predict anyone of them from the other three by use of thermodynamic method. This method was also proved to be helpful to test the thermodynamic consistancy of the experimental data. (b) We attempted to correlated these binary data and predict the properties of multicomponent systems. Our results indicated that although aqueous hydrogen iodide is a strong electrolytic solution

by use of NRTL equation and expanding its parameters into polynomial series of temperature

it was able to predict multicomponent equilibrium from binary data.
