Abstract

In a process for preparing alkylamines by reacting amines and aliphatic aldehydes in the presence of free hydrogen on a fixed bed catalyst in a reactor in which amines and aldehydes are mixed in the catalyst bed after being fed in in separate streams, only the aldehyde stream or only the amine stream is preheated during the feeding in.
