ABSTRACT:
The present invention provides a selective process for the manufacture of diethylenetriamine from ethylenediamine, ethanolamine, and urea. The process comprises a reaction cycle in which ethylenediamine, ethanolamine, and urea are first reacted in step (a) to form aminoethylethyleneurea and ethyleneurea, which in turn are hydrolyzed in a second reaction step (b) to diethylenetriamine and ethylenediamine. The ethylenediamine made in the second reaction step (b) may be recycled to the first reaction step (a).
