摘要:Process for the preparation of polyalkylenepolyamines by homogeneously catalyzed alcohol amination, in which aliphatic amino alcohols are reacted with one another or aliphatic diamines or polyamines are reacted with aliphatic diols or polyols with the elimination of water in the presence of a homogeneous catalyst and in the presence of hydrogen gas. Polyalkylenepolyamines obtainable by such processes and polyalkylenepolyamines comprising hydroxy groups, secondary amines or tertiary amines. Uses of such polyalkylenepolyamines as adhesion promoters for printing inks, adhesion promoters in composite films, cohesion promoters for adhesives, crosslinkers/curing agents for resins, primers for paints, wet-adhesion promoters for emulsion paints, complexing agents and flocculating agents, penetration assistants in wood preservation, corrosion inhibitors, immobilizing agents for proteins and enzymes.

摘要:The invention relates to a method for the production of polyalkylene polyamines by homogeneously catalyzed alcohol amination, wherein aliphatic alkanolamines are reacted with each other or aliphatic diamines or polyamines are reacted with aliphatic diols or polyols in the presence of a homogeneous catalyst while eliminating water and in the presence of hydrogen gas. The invention further relates to polyalkylene polyamines, which can be obtained by said methods, and to polyalkylene polyamines which contain hydroxyl groups, secondary amines or tertiary amines. The invention finally relates to uses of said polyalkylene polyamines as adhesion promoters in inks, adhesion promoters in composite films, cohesion promoters in adhesives, cross-linkers/hardeners for resins, primers for paints, wet adhesion promoters for dispersion paints, complexing agents and flocculants, penetration auxiliaries for use in wood preservation, corrosion inhibitors, and immobilization agents of proteins and enzymes.
