The vapor-phase Beckmann rearrangement of cyclohexanone oxime over an HY zeolite calcined at high temperatures was investigated. Cyclohexanone oxime was rearranged into ε-caprolactam with high conversion at 573 K over an HY zeolite calcined at 873 K. The activity decay was slight, while oxime conver...
