摘要

由溶剂化缔合观点

推导出了计算难挥发物质在超临界流体(SCF)中平衡溶解度的缔合模型.利用文献数据对缔合模型的适用性进行了考察

得到了较满意的结果.以缔合模型为基础

对SCF的溶解能力及其随诸因素影响的变化规律进行了分析和讨论

由此得出的一些推论均能和实验现象一致.

Abstract

An association model applicable to calculating the solubilities of low-volatile substances in supercritical fluids was derived and compared with experimental data available in the literature

showing good agreement over wide ranges of temperatures and pressures: 1.01≤Tr≤1.23; 0.96≤Pr≤9.66 On the basis of this model

the solvability of supercritical fluids and its changing tendency with other variables over the range likely to be encountered in supercritical fluid extraction were discussed. Some deductions derived from the model showed good agreement with experimental results.
