A novel modification for silicalite-1 with high stability and selectivity in vapor phase beckmann rearrangement of cyclohexanone oxime
This paper presents a novel modification of highly siliceous MFI zeolites with hydrofluoric acid treatment: Silicalite-1 undergone such treatment exhibited remarkable improvements in stability and selectivity for Beckmann rearrangement of cyclohexanone oxime, which are even much better than those obtained by basic modification.
