INTRODUCTIONrnThe 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[1],boria-alumina[2], and zeolites including Y [3], those with MFI-structure [4] and β[5] have been studied.However, no generally accepted understanding about the reaction mechanism has been achieved.rn
