摘要
将乙二醇与环己酮的缩合反应作为探针反应,对不同酸催化剂的催化活性进行了表征.在此基础上,提出了以反应速率来定量表征催化剂的反应活性,并以空白实验的活性为基础,提出了相对活性的概念.该表征方法简单快捷,能比较直观地反映出不同催化剂的活性大小.
In this article, the ketalization of cyclohexanone and glycol was used as the probe reaction to characterize activities of various acid catalysts. On this basis, we came up with a method of using reaction rate to quantificationally characterize activity of catalyst. Based on the acticity of blank experiment , a conception of relative activity was raised. This method is simple and fast and can directly show different activities of different catalysts.
