【摘要】 本文在简要述及超临界流体特性之后,着重讨论了超临界流体条件对化学反应的若干效应:(1)降低反应温度;(2)维持非均相催化剂的活性;(3)便于考察解质粘度对反应的影响;(4)使反应在均相进行,便于产物从反应区移去;(5)提高反应速率,改变反应历程等。更多还原

【Abstract】 After briefly discussing SCF characteristics,this paper gives more attention to the effects of SCF condition on chemical reactions: 1.lowering of the reaction temperature, 2.maintainance of high activity of a heterogeneus catalyst, 3.convenience in studying the viscosity effects of solvent on the reaction behavior, 4.Performing a reaction in homogeneous phase,and allow the product to be easily removed from the reaction region, 5.increasing the reaction rate and changing the reaction course.更多还原
