摘要: A process for preparing amines of the formula (II) R1—NH—CH2—CH2—NH2 (II) in which R1 is hydrogen or radicals of the formula x is integers from zero to two, by reacting nitriles of the formula (I) R2—NH—CH2—CN (I) in which R2 is hydrogen or radicals of the formula and R3 is the NC— or H2N—CH2- radicals and x is integers from zero to two, with hydrogen in the presence of a catalyst in suspension mode or in a fixed bed, wherein the space velocity on the catalyst, based on the catalyst surface area, is 10−6 to 10−4 kg of nitrile of the formula (I) per m2 of catalyst surface area and hour, the catalyst surface area being determined by the BET method.
