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.

Polyetheramine production method

Process and apparatus for the continuous preparation of polymers Two reaction partners (starting materials) are stored in separate reservoirs and and are transported using overpressure via heated heat exchangers into a micromixer by means of control and metering devices which can be metering pumps. In the heat exchangers , the starting materials are heated, separately in each case, to the extent that during the mixing operation in the micromixer the required reaction temperature is immediately reached. The polymerization takes place in a downstream tube reactor which consists of tubes which are connected in series.
