Deactivation mechanisms of Nb <sub>2</sub> O <sub>5</sub> catalyst for esterification of dimethyl adipate: crystal transformation and acid site coking
Nb 2 O 5 catalyst deactivation in adiponitrile synthesis is caused by carbon deposition and phase transformation. Proper acidity and site control boost selectivity, offering strategies for enhanced catalyst lifespan and efficiency.
