Abstract:
1. A method of making a product mixture of linear high molecular weight polyamines having four or more N atoms comprising the steps of: (a) providing a reaction composition comprising one or more nitrogen-containing compounds comprising a first component that has at least two non-tertiary amine groups separated from one another by at least a ternary or higher carbon atom spacing (C3 or greater spacing) and, optionally, a second component that has at least two nitrogen containing groups separated from one another by a binary or higher carbon atom spacing (C2 or higher spacing); wherein the molar content of the first component is at least 95% of the reaction composition; and (b) subjecting the reaction composition to a transamination reaction in the presence of a hydrogenation/dehydrogenation catalyst to obtain the mixture of linear high molecular weight polyamines having four or more N atoms.
