Investigating the uptake of cyclohexanone oxime in hierarchically-porous catalysts for the Beckmann rearrangement

Abstract: Sustainable technologies for polymer manufacture remain an important target of catalyst research. Thus, we have developed a hierarchically-porous (HP) SAPO (containing interconnected micro- and meso-porous networks) that effects the acid-catalysed Beckmann rearrangement of cyclohexanone oxime to E-caprolactam (the precursor to nylon-6) with enhanced yield and lifetime, relative to the microporous (MP) analogue. Our earlier QENS study has revealed the contrasting mobility of oxime in HP and MP SAPOs, and evidenced substrate-framework interactions in the HP SAPO. In order to gain further insight into the driving force for the interaction between the oxime and HP SAPO, and to inform our previous QENS experiment, we propose to study the adsorption process in HP and MP SAPO-5, and to determine the structure and distribution of the adsorbed oxime within the catalyst pores.
