Process to prepare higher ethylene amines or urea derivatives thereof

The present invention relates to a to prepare ethylene amines of the formula NH2-(C2H4-NH-)pH wherein p is at least 2, or derivatives thereof wherein one or more units -NH-C2H4-NH- may be present as a cyclic ethylene urea unit comprising the step of reacting an ethanolamine-functional compound OH-(C...

Zusammenfassung:The present invention relates to a to prepare ethylene amines of the formula NH2-(C2H4-NH-)pH wherein p is at least 2, or derivatives thereof wherein one or more units -NH-C2H4-NH- may be present as a cyclic ethylene urea unit comprising the step of reacting an ethanolamine-functional compound OH-(C2H4-NH-)qH or HO-(C2H4-NH)q-C2H4-OH wherein q is at least 1, an amine-functional compound NH2-(C2H4-NH-)rH wherein r is at least 1 in the presence of a carbon oxide delivering agent and water, with a molar ratio of water : carbon oxide delivering agent of from 0.01:1 to 2:1.
