Zeolite Catalysed Rearrangement of Aromatic Amines

Abstract The influence of reaction conditions, catalyst parameters and reactants on the rearrangement of aromatic amines to substituted methylpyridines catalysed by zeolites has been examinated. Passivation of the outer surface has been used to increase the selectivity. Experiments have been carried out with different zeolite types, with substituted anilines and with naphthylamines in order to prove a new model for the mechanism of the reaction.
