| 摘 要： | 环己酮肟Beckmann重排制己内酰胺是重要的工业过程。本文较详细地介绍了不使用浓硫酸催化的反应，主要有气固相反应、固液相反应、离子液体系及超临界水条件下的反应。研究表明：气固相反应中，副产物较多，催化剂易失活，使用寿命短；固液相反应条件温和，且副产物少；离子液体系和超临界水条件下的Beckmann反应中，可避免使用有机溶剂，且反应副产物少。

| Abstract: | The Beckmann rearrangement of cyclohexanone oxime to caprolactam is an important industrial procedure . The reactions which proceed in gas solid phase; solid liquid phase; ionic liquid system and supercritical fluid without use of concentrated sulfuric acid as catalyst are introduced. The results show that, when reaction proceeds in gas solid phase, more by product is produced and the catalyst is easily inactivated with short service life. When in the solid liquid phase, reaction condition is mild and by product is less. While under ionic liquid system and supercritical fluid, the use of organic solvent can be omitted and by product is less. |
