Abstract
Official abstract text for this publication.
A transamination process is described to prepare polyamine product mixtures from reactants comprising mixed nitrogen-containing compounds with binary carbon spacing between nitrogen-containing groups (a binary component). A second nitrogen-containing component with a second carbon atom spacing between nitrogen-containing groups may also be employed. The molar ratio between the binary and second components can be adjusted to customize the product composition for desired end uses.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of making a cyclic polyamine-containing product mixture comprising the steps of: (a) providing a reaction composition comprising one or more nitrogen-containing compounds having a binary component that has at least two non-tertiary amine groups separated from one another by a binary carbon atom spacing (C2 spacing) and, a second component comprising a second nitrogen-containing compound having (i) at least two non-tertiary amine groups separated fro…
