Abstract
The invention relates to a process for the preparation of an aminonitrile by partially hydrogenating a nitrile compound with two or more nitrile groups in the presence of a catalyst which contains a metal from group 8 of the periodic system of the elements, the hydrogenation being carried out under water-free reaction conditions and the catalyst having been treated with an alkanolate. Preferably, the catalyst is a Raney nickel or Raney cobalt catalyst which has been pretreated with an alkali metal alkanolate or an earth alkali metal alkanolate such as sodium or potassium methanolate.
