| 摘 要： | The Beckmann rearrangement of cyclohexanone oxime is an important reaction for obtaining ε-caprolactam, the raw material of nylon 6 fibers. Currently, the widely used technologies for the production of cyclohexanone oxime produce large amounts of byproducts. For the Beckmann rearrangement, many solid acid catalysts such as alumina, boria-alumina, and zeolites including Y, those with MFI-structure and β have been studied. However, no generally accepted understanding about the reaction mechanism has been achieved.
