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 Br&#xf8;nsted 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.

Hierarchical aluminophosphates as catalysts for the Beckmann rearrangement

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.

Nanoparticle catalysts for conversion of cyclohexanol to cyclohexanone

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 &#x3b5;-caprolactam produced from cyclohexanone oxime and high conversion and selectivity for &#x3c9;-laurolactam produced from cyclododecanone oxime.

The disclosure describes a new class of isomorphously metal-substituted aluminophosphate materials with high phase purity that are capable of performing selective Br&#xf6;nsted acid catalyzed chemical transformations, such as transforming alcohols to olefins, with high conversions and selectivities using mild conditions. Isomorphous substitutions of functional metal ions for both the aluminum ions and the phosphorous ions were successful in various AlPO structures, along with multiple metal substitutions into a single aluminum site and/or a phosphorous site. This invention can be used towards the catalytic conversion of hydroxylated compounds of linear and/or branched moiety with the possibility of being substituted to their respective hydrocarbon products, preferably light olefins containing 2 to 10 carbon atoms, among other chemistries.
