Abstract
Process for the continuous preparation of aminoalcohylene phosphonic acids from an amine and/or its hydrochloride, a carbonyl compound and a trivalent phosphorus compound, characterized in that the simultaneously introduced reaction partners are preferably reacted in amounts preferably in amounts stoichiometric, in at least two stages connected in series, possibly with evacuation of the gases that are formed, maintaining in the first stage a reaction temperature between 30 and 90º c, preferably from 40 to 60ºC and maintaining in the second stage the boiling temperature, and reacting the reaction participants in volumes such that the reaction lasts in the first stage at least 10 minutes and in the second stage 30 to 120 minutes, preferably 60 minutes, and after that the product is continuously removed.
