METHOD FOR PURIFYING ALIPHATIC AMINONITRILES |
| 摘要 |
The invention concerns a method for purifying aliphatic aminonitriles and more particularly amino-6 capronitrile, which consists more precisely in subjecting amino-6 capronitrile to hydrogenation by molecular hydrogen, in the presence of a catalyst containing at least a metal selected among palladium, platinum, ruthenium, osmium, iridium, rhodium and a promoting or preconditioning agent to improve the selectivity of hydrogenation.
