ABSTRACT:
A method for converting a bis(polyalkoxy)-N-alkylamine to a bis(diaminopolyalkoxy)-N-alkylamine has been discovered. The method comprises alkoxylating an alkylamine to a bis(polyalkoxy)-N-alkylamine. The alkylamine is selected to sterically hinder the resulting tertiary amine. The alkoxylate is then catalytically aminated according to well known procedures with a high yield of the diamine resulting.
Compounds prepared by this method are of the formula:
