| 摘 要： | 基于在超临界萃取过程中，同时存在超临界流体相－固相相平衡和超临界相缔合反应平衡的假设，提出一一个用于超临界萃取溶解度计算的缔合模型。该模型式用于２７个固体溶质和５个液体溶质在超临界溶剂中溶解度的计算，其平均相对偏差绝大多数体系均小于１０％。

| Abstract: | An association model for calculations of solubilities in supercritical extraction was proposed on the assumption that the gas solid phase equilibria and the association reaction equilibria in supercritical fliud are existed simutaneously in supercritical extraction processes. The formula was used to calculate the solubilities of 27 solid solutes and 5 liquid solutes in solvents(carbon dioxide and ethylene). The average relative deviations of soluilities are less than 10% in the most cases. |
