Strong basic sites accelerate the deactivation of oxide catalysts supported on FSM-16 for the vapor-phase beckmann rearrangement of cyclohexanone oxime

Article abstract of DOI:10.1246/cl.1999.1319

The acidic and basic properties of FSM-16-supported Al₂O₃, ZnO or CdO were determined by the temperature-programmed desorption (TPD) of ethylamine. Relationship of the deactivation rate of the catalyst during the vapor-phase Beckmann rearrangement with the acidic and basic properties was studied. It was found that the deactivation was accelerated with an increase in the amount of the strong basic sites.
