Abstract

Process for the production of multinuclear aromatic polyamines, by condensation of aromatic amines with formaldehyde, in the presence of water and acid catalysts, characterized in that a) the aqueous condensation mixture having been reacted is extracted with a hydrophobic solvent, optionally with the addition of the same aromatic amine that was also used for the condensation, b) the solvent phase thus obtained is processed to the polyamine and c) the aqueous phase is recycled in a circuit at the beginning of the process.
