    摘要: A redox ammoximation process in which a ketone or aldehyde is reacted with ammonia and oxygen in the presence of a catalyst, wherein: the catalyst is an aluminophosphate based redox catalyst having the qualitative general formula (I) M1M2AlPO-5 (I) in which M1 is at least one transition metal atom having redox catalytic capability; M2 is at least one metal atom in the (IV) oxidation state; M1 and M2 are different from each other; and a proportion of the phosphorous atoms in the M1M2AlPO-5 type structure are replaced by M2 atoms.

    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.
