GAS AND LIQUID PHASE CATALYTIC BECKMANN REARRANGEMENT OF OXIMES TO PRODUCE LACTAMS

摘要

Methods for producing lactams from oximes by performing a Beckmann rearrangement using a silicoaluminophosphate catalyst are provided. These catalysts may be used in gas phase or liquid phase reactions to convert oximes into lactams. High conversion of oxime and high selectivity for the desired lactams are produced using the disclosed methods, including high conversion and selectivity for ε-caprolactam produced from cyclohexanone oxime and high conversion and selectivity for ω-laurolactam produced from cyclododecanone oxime.
