摘要

测定了温度为 32 3.15、 32 8.15、 333.15K

压力为 3.0～ 2 4 .0MPa条件下苯乙烯 (ST)在超临界二氧化碳 (SC -CO2 )中的溶解度

并根据溶剂化缔合概念、相平衡规则及高压对缔合平衡移动的影响导出溶解度数学模型 .本模型的ST溶解度预测值与实验值吻合良好 .用文献发表的溶解度数据对模型的适用性进行验算

也获得了较为满意的结果

Abstract

The solubilities of styrene in supercritical carbon dioxide under different supercritical conditions are determined.The range of temperature covered is 323.15-33.15K and pressure 3.0-24.0MPa.A model representing solubility behavior is derived from the solvation concept

the equilibrium constant of high-pressure reaction and the rules of phase equilibrium. It is tested by experimental results with good agreement. Also

some experimental results from the literature are reproduced by means of this model.
