Abstract

The invention relates to a process for the preparation of polyalkylenepolyamines by catalyzed alcohol amination, in which(i) aliphatic aminoalcohols are reacted with one another or(ii) aliphatic diamines or polyamines are reacted with aliphatic diols or polyols with the elimination of water in the presence of a catalyst.
