Abstract: The invention relates to a process for isolating methylglycinenitrile-N,N-diacetonitrile (MGDN) from an aqueous emulsion which comprises MGDN and has an MGDN content of 3-50% by weight in a crystallizer, comprising the steps: (a) the aqueous emulsion is, starting from a temperature above the solidification point, cooled to a temperature below the solidification point, the cooling rate averaged over time not exceeding 5 K/h, until substantially the entirety of the emulsified MGDN has solidified, (b) the resulting aqueous suspension is cooled further and/or concentrated, and the cooling rate may be greater than in step (a).

Abstract: The invention relates to a process for preparing N-phosphono-methylglycine by reacting a hexahydrotriazine compound with a triacyl phosphite in an organic solvent, hydrolyzing the resulting phosphono compound after prior extraction into an aqueous phase and separation from the organic phase. The process avoids decomposition of the organic solvent during hydrolysis.

Abstract: Disclosed is a method for reducing the formation of acrylamide during heatin g of amino group-containing compounds in the presence of reducing substances. Said method is characterized by the fact that the amino group-containing compounds are mixed with ascorbic acid and/or vitamin E before being heated.

Abstract: Procedimiento para la preparación de N-fosfonometilglicina de la fórmula (1) en la que a) se hace reaccionar un derivado de hexadihidrotriazina de la fórmula (2) en donde X representa CN, COOZ, CONR1R2 o CH2OY, Y representa H o un resto que puede ser intercambiado fácilmente por H; Z representa H, un metal alcalino, un metal alcalinotérreo, alquilo C1-18 o arilo opcionalmente sustituido por alquilo C1-4, NO2 o OC1-C4-alquilo; R1 y R2 que pueden ser iguales o diferentes, representan H o alquilo C1-4 con un triacilfosfito de la fórmula (3): P(OCOR3)3 en donde los restos R3, que pueden ser iguales o diferentes, representan alquilo C1-18 o arilo, que está opcionalmente sustituido por alquilo C1-4, NO2 o OC1-4-alquilo en un solvente orgánico; b) se extrae la mezcla de reacción obtenida con agua o una solución acuosa de un ácido o una solución acuosa de una base; c) se separan las fases; y d) se hidroliza el producto obtenido en la fase acuosa. Por este procedimiento se evita la descomposición del solvente orgánico durante la saponificación. La fosfonometilglicina o glifosato es un herbicida total que es utilizado ampliamente.
