摘要
超临界流体可将化学反应的产物快速有效地移出反应体系，避免产物进一步发生副反应，并可提高反应速率或反应的转化率。在超临界流体介质中进行的化学反应，其反应速率可以大幅度提高。这些应用归因于超临界流体的特性，其中根本原因之一是超临界流体分子与溶质分子之间存在着超强相互作用，在宏观上这种作用表现为溶质具有绝对值很大的负的偏摩尔体积。
Supercritical fluid can remove the products of chemical reactions from the surroundings effectively and quickly so as to prevent the occurrence of further reactions and improve the reaction rate or reactionchange rate,The chemical reaction taking place in the medium of super critical fluid may have the reaction rate increased to a large extent.All this owes to the characteristics of supercritical fluid,one of whichis that there exists super interaction between supercritical fluid moleculars and solute moleculars,Macroscopically,it is shown that the solute has greater negative partial molar volume in absolute value.
