Abstract
The present invention provides methods of manufacturing ethyleneamines that makes use of an ethyleneamine-generating process that is coupled to a transamination process. The combination of an ethyleneamine-generating process with a transamination process improves the mix flexibility that can be obtained from the single process allowing the production of ethyleneamine compositions having an improved and more desirable product mix.
