The present invention relates to a process for preparing primary amines, wherein a nitrile in the presence of a nickel fixed-bed catalyst and of ammonia to obtain the corresponding primary amine is hydrogenated. The hydrogenation is carried out in a device (V1), for example in a reactor, . In this device (V1) at least one compound is added continuously in particular, during the (I) hydrogenation procedure Recurring or, the is based on alkali metals, alkaline earth metals and/or rare earth metals, for example, as compound (I) is added an aqueous lithium hydroxide solution.
