  • Patent number: 9162995
    Abstract: The present invention provides strategies for making higher weight, cyclic polyamines from lower molecular weight, cyclic polyamine starting compounds via transamination. The higher molecular weight, cyclic polyamines are structurally similar to the lower molecular weight, cyclic polyamine starting compounds. The reactants used in the present invention include a cyclic polyamine component that comprises at least two amine groups separated from one another by at least a binary carbon atom spacing, and that can be transaminated to form a higher molecular weight, cyclic polyamine compound. The higher molecular weight, cyclic polyamine has at least two cyclic rings joined to one another through a nitrogen-containing hydrocarbyl group. Each of the cyclic rings contains two amine groups separated from one another by binary carbon atom spacing.
