The invention provides a process for preparing polyetheramines of the formula (1), R(NRR), in which n is a number from 1 to 20, Rrepresents an organic radical that contains between 2 and 600 oxalkylene groups, and Rand Rare alike or different and represent hydrogen or an organic radical having 1 to 400 carbon atoms, by combining a compound of the formula (2), H(NRR), with a compound of the formula (3), R(OH), in the presence of hydrogen with a metal-containing catalyst whose metal content, based on the dry, reduced catalyst excluding any support material that may be present, is composed either of at least 80% by mass of cobalt or, in the case of Raney catalysts, of at least 80% by mass of metals from the group consisting of cobalt and aluminium, the catalyst containing less than 5% by mass of copper.

Process for preparing polyetheramines

The invention relates to a method for producing amines of formula (1), wherein Ris an organic group containing from 2 to 600 alkoxy groups and Rand Rgroups 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 a compound of formula (3) in the presence of hydrogen with a metal-containing catalyst, wherein the metal content in cobalt is equal to or greater than 80% by weight.
