互溶双液系气液平衡相图计算机绘制及其应用

Computer drawing of the phase diagram of completely mutually soluble double-fluid system and it's application

由于完全互溶双液系平衡相图的绘制需要许多组数据,而且要绘制折光率-组成工作曲线,数据处理和绘图工作量较大.文章采用计算机程序方便地绘出气液平衡相图,并求出了溶液组成为任意值时(以摩尔分数为0.75为例)的气相组成和沸点分别为0.5772,64.9737℃.

The phase diagram of completely mutually soluble double-fluid system needs not only many sets of data, but also map work curve of refract rate-composition , data processing and mapping larger workload. This article takes the chemical physics experiments ＂ Binary Liquid-Vapor Equilibrium Phase Diagram ＂ for the study, using the computer program to draw the Liquid-Vapor Equilibrium Phase Diagram conveniently, and can extract composes is 0.75 time gas phase composition and the boiling point respectively is 0. 577 2, 64. 973 7℃.
