Preparation of N-alkylbis(3-aminopropyl)amines by the catalytic hydrogenation of N-alkylbis(cyanoethyl)amines.


An improved process for the preparation of N-alkylbis(3-aminopropyl)amines is described. These triamines are of interest as monomers for the condensation polymerization with esterified carbohydrate diacids (aldaric acids) to generate the corresponding poly(4-alkyl-4-azaheptamethylene aldaramides). The triamine synthesis is comprised of two efficient steps… (More)
