Method for the production of diaminodiarylmethanes

A process for preparing diaminodiarylmethanes comprising the steps

• a) reacting an aromatic amine with a methylene-donating agent in the presence of homogeneous acid catalysts,
• b) removing the homogeneous acid catalyst from the reaction product,
• c) working up and purifying the reaction product,
• which comprises removing the homogeneous acid catalyst from the reaction mixture by adsorption to a solid adsorbent and the absorbent is regenerated with the amine which is used as the feed product of the process.
