摘要： Methods for converting an alcohol, such as cyclohexanol to a ketone, such as cyclohexanone, include reacting the alcohol in the presence of a catalyst and oxygen to produce the ketone. In one exemplary embodiment, the catalyst comprises a microporous copper chloropyrophosphate framework including a plurality of noble metal nanoparticles. In one exemplary embodiment, the noble metal nanoparticles include at least one metal selected from the group consisting of platinum, palladium, and gold.

摘要： Methods for producing lactams from oximes by performing a Beckmann rearrangement using a hierarchical porous aluminophosphate catalyst having interconnected microporous and mesoporous networks are provided. Exemplary catalysts include a plurality of weak Brønsted acid active sites, including silicon-containing aluminophosphates having the IZA framework code AFI, such as SAPO-5, CHA, such as SAPO-34, and FAU, such as SAPO-37.

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.
