Synthesis of aliphatic polyamines |
摘要 |
An improved process for selectively forming aliphatic polyamines from aliphatic polynitriles having 2 to 3 atoms between cyano groups by reacting aliphatic polynitrile, with hydrogen in the presence of a primary or secondary amine, through a fixed bed reactor while continuously contacting the reactants with granular Raney cobalt packed therein.
