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: 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).
