Abstract
This invention is directed to a process for the production of polyaryl amines containing methylene bridges. These compounds are prepared from aryl amines and formaldehyde in the presence of acids and water and the catalyst is simultaneously recovered. The polyaryl amine salt solutions produced by conventional methods are mixed with the starting aryl amines to form at least partially heterogeneous systems, optionally after the addition of water and optionally in the presence of hydrophobic solvents. Polyaryl amines are exchanged by aryl amines to form on the one hand, mixtures of polyaryl amines and aryl amines and on the other hand, an aqueous solution of the acid in the form of a salt of the aryl amine.
