| 摘 要： | 用化学缔合方法对固体物质在超临界流体中的溶解度进行了研究,考虑到了含和不含夹带剂两种情况。基于化工热力学和化学缔合反应原理,推导出了固体溶质在超临界流体中的溶解度模型,当不含夹带剂时,该模型可转化为常用的溶解度计算公式。采用实验数据证实,该模型的总平均误差小于5%,验证了模型的正确性。

| Abstract: | Solubility of solids in supercritical fluids with or without cosolvent was studied by a chemical association reaction method. Based on the thermodynamic and association reaction equilibrium theories, a model for the solubility of solids in supercritical fluids under association reactions was developed, by which a normal solubility calculation model could be developed for the case without cosolvent and association reactions. The model was tested and justified with the experimental data collected from the literature. |
