摘要： A process in which a Raney nickel or Raney cobalt hydrogenation catalyst is suspended in an aqueous liquid for feeding of the catalyst into a reaction medium in which an amine is prepared by continuous catalytic hydrogenation of a nitrile reactant is improved by including in the aqueous liquid a portion of the reaction medium containing an amount of the amine sufficient to substantially inhibit foaming of the catalyst suspension.
