摘要

在恒温下测量了二甲基甲酰胺和苯乙烯、邻二甲苯构成的二元系总蒸气压.采用一非无热缔合溶液模型

拟合总压一组成数据

计算结果与恒温流动法测量的汽液平衡结果相符.

Abstract

At 60℃

the total pressure of dimethylformamide with styrene and o-xylene respectively was measured. A nonathermal associated solution model Was used to treat the pressure-composition data

and the associated constants were listed. It has shown that this model is better than the regular associated model for the systems in which the mole volumes of the components of the binary solution are quite different. The calculated results are in agreement with the experimental results of vapour-liquid equilibrium by flowing method at constant temperature.
