    Abstract: La invencion se relaciona con un proceso para aislar metilglicinanitrilo-N,N-diacetonitrilo (MGDN) de una emulsion acuosa que comprende MGDN y tiene un contenido de MGDN de 3-50% en peso en un cristalizador, que comprende los pasos: (a) la emulsion acuosa, empezando de una temperatura superior al punto de solidificacion, se enfria a una temperatura inferior al punto de solidificacion, el regimen de enfriamiento promediado sobre el tiempo no excediendo 5 K/h, hasta que substancialmente la totalidad del MGDN emulsionado se ha solidificado, (b) la suspension acuosa resultante se enfria adicionalmente y/o concentra, y el regimen de enfriamiento puede ser mayor que en el paso (a). (Figura 2).

    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.
