Claim:
1. A process for preparing a lipophilic polyalkylenepolyamine, by homogeneously catalyzed alcohol amination, the process comprising: (i) reacting aliphatic amino alcohols with one another, or (ii) reacting an aliphatic diamine or polyamine with an aliphatic diol or polyol, to obtain a reaction mixture, with elimination of water, in the presence of a homogeneous transition metal complex catalyst, wherein: at least one starting material of the aliphatic amino alcohols, aliphatic diamine, polyamine, aliphatic diol or polyol comprises an alkyl or alkylene group having five or more carbon atoms; and the process further comprises, after the reacting, performing a phase separation into a nonpolar phase and a polar phase, such that the lipophilic polyalkylenepolyamine is present in enriched form in the nonpolar phase.
