Abstract
An improved process for selectively forming noncyclic, aliphatic polyamines from the corresponding aliphatic polynitriles by reacting the polynitrile with hydrogen at low temperature under a pressure of from 50 to 5,000 psi in a fixed bed reactor while continuously contacting the reactants with granular chromium and nickel promoted Raney.RTM. cobalt packed therein.
