POLYETHERAMINE PRODUCTION METHOD.

摘要

The invention relates to a method for producing amines of formula (I), wherein R² is an organic group containing from 2 to 600 alkoxy groups and R¹ and R³ groups are similar or different and represent a hydrogen atom or an organic group containing from 1 to 400 carbon atoms. The inventive method consists in bringing a compound of formula (2) into contact with a compound of formula (3)in the presence hydrogen with a metal-containing catalyst, wherein the metal content in cobalt is equal to or greater than 80 % by weight.
