A process for the production of piperidine or its alkyl homologues by the catalytic hydrogenation of pyridine or its alkyl homologues

摘要

In the production of piperidine or its alkyl homologues by the catalytic hydrogenation of pyridine or its alkyl homologues the process is carried out using a molar excess of hydrogen at 100-200 DEG C. and a pressure up to 250 atm. gauge in the presence of a catalyst containing at least 30% by weight of metallic cobalt or of metallic cobalt and metallic nickel on a carrier of activated alumina.
