Vapor phase Beckmann rearrangement of cyclohexanone oxime over a novel tantalum pillared-ilerite
Abstract
The vapor phase Beckmann rearrangement of cyclohexanone oxime has been studied using a novel tantalum pillared-ilerite as catalyst: the cyclohexanone oxime conversion rate reaches 97.1% and the selectivity for ε-caprolactam is up to 89.1% at 350 °C.
