Process for the preparation of dibenzylamine

摘要

The present process involves preparing dibenzylamine through the hydrogenation of benzaldehyde in the presence of ammonia and a catalyst containing palladium using a small amount of solvent or dispersion medium. With the present process, dibenzylamine can be prepared with high selectivity in a relatively short reaction time and with complete conversion of the benzaldehyde, at which makes it commercially attractive. In the present process, a palladium-carbon catalyst is preferably used.
