摘要
以沸石为催化剂,通过环己酮肟发生贝克曼重排制备己内酰胺的方法是工业生产己内酰胺的重要途径.新的合成途径及催化剂的发展与应用是目前研究的重点.本文评述了近年来经贝克曼重排合成己内酰胺在新工艺开发、催化剂性能优化及新催化剂开发方面研究和应用进展,并对今后己内酰胺研究发展方向提出了意见.
Beckmann rearrangement of cyclohexanone oxime with zeolite as catalyst is an very important way of ε-caprolactam synthesis.Now,new synthetic route and new kind of catalyst are the aim of research.The progress of ε-caprolactam synthesis via Beckmann rearrangement in recent years was introduced in this article in some respects such as the new production methods and technology,the development of new kind of catalyst and its properties,and structural modification of original catalysts etc.And then,an opinion wa...
