A method for the manufacture of aminoalkylene phosphonic acids broadly is disclosed. In the essence, an amine corresponding to a specific formula is reacted in aqueous medium with phosphorous acid and formaldehyde to thereby yield a medium insoluble reaction product. The insoluble product formed i.e. the aminoalkylene phosphonic acid can be separated, optionally washed, and recovered. This process yields high purity and selectivity reaction products. The excess phosphonic acid can be recycled into the processing sequence.

L'invention concerne un procédé pour produire une large gamme d'acides phosphoniques d'aminoalkylène. Ce procédé consiste essentiellement à faire réagir une amine présentant une formule spécifique en milieu aqueux avec de l'acide phosphorique et du formaldéhyde pour obtenir un produit réactionnel non soluble dans ledit milieu. Le produit insoluble formé, c'est-à-dire l'acide phosphonique d'aminoalkylène, peut être séparé, éventuellement lavé, et récupéré. Ce procédé permet d'obtenir des produits présentant un degré de pureté et de sélectivité élevés. L'excédent d'acide phosphonique peut être recyclé dans la séquence de traitement.
