In a process for the N-alkylation of amines in which alcohols are reacted with alkylamines or dialkylamines in the presence of hydrogen, the reaction takes place on a catalyst based on copper and magnesium silicate and containing, in each case independently, 0 to 2% by weight of BaO, Cr.sub.2 O.sub.3 and/or ZnO. The amines employed are mono- or dimethylamine or mono- or diethylamine, the alcohols employed are .alpha.,.omega.-diols, in particular diethylene glycol or pentanediol. In particular there is reaction of diethylene glycol with monomethylamine and/or monoethylamine to give N-methylmorpholine and/or N-ethylmorpholine.
