ABSTRACT:
A process for the preparation of predominantly non-cyclic polyalkylenepolyamines comprising contacting a difunctional aliphatic alcohol with ammonia or a primary or secondary aliphatic amine in the presence of a catalyst selected from the group consisting of Group VB metal oxides, niobium phosphates, tantalum phosphates, and mixtures thereof. For example, monoethanolamine is aminated by ethylenediamine to predominantly linear and branched polyethylenepolyamines in the presence of a catalyst containing niobium oxide supported on boehmite alumina.
