Investigating the diffusion of cyclic oximes in hierarchically-porous catalysts for the Beckmann rearrangement

Abstract: Caprolactam (CL) is a high-value chemical precursor to nylon-6. On an industrial scale an aggressive liquid-acid catalyst is used to transform C6-oxime to CL. Due to environmental issues and low-selectivities, there is a necessity to find a solid-acid alternative. Silicon-containing aluminophosphates (SAPOs) have been successful due to their tunability, high yields, and recyclability. However, where the small channels of microporous SAPOs restrict substrate movement and increase pore blockage, hierarchically-porous (HP) SAPOs (containing larger mesopores) exhibit longer lifetimes and improved yields. Previous QENS results were encouraging in picking up differences in diffusion modes within microporous SAPOs. This experiment is targeted at solely hierarchical structures to probe diffusion, in hitherto unexplored porous structures, containing interconnecting micropores and mesopore
