ABSTRACT:
Catalytic hydrogenation of furfurylamine or tetrahydrofurfurylamine in the presence of a cobalt-based catalyst into piperidine can be industrially carried out in an organic solvent, wherein addition of ammonia is not needed. It has been believed heretofore that the presence of ammonia in the hydrogenation is essential in such catalytic hydrogenation.
