Abstract

Se describe un procedimiento para la fabricacion de ácido N-fosfonometiliminodiacético por medio de la transformacion de ácido iminodiacético con ácidofosforoso y formaldehído en solucion acuosa, en presencia de un ácido mineral fuerte,procedimiento que está caracterizado porque la reaccion es realizada auna temperatura de 110 a 150*C bajo una atmosfera de gas de proteccion. Las ventajas principales de este procedimiento son los elevados rendimientos y lapureza con respecto alácido N-fosfonome tiliminodiacético, como así también el consumo casi estequiométrico de materias primas y, por lo tanto, las menorescantidades de desechos.A process is described for the manufacture of N-phosphonomethyliminodiacetic acid by means of the transformation of iminodiacetic acid with acid phosphorus and formaldehyde into an aqueous solution, in the presence of a strong mineral acid, a procedure characterized in that the reaction is carried out at a temperature of 110 to 150 * C under a protective gas atmosphere. The main advantages of this procedure are the high yields and stiffness with respect to the N-phosphonome tiliminodiacetic acid, as well as the almost stoichiometric consumption of raw materials and, therefore, the lower amounts of waste.
