Abstract
Se provee un método para aislar metilglicinanitrilo-N,N-diacetonit rilo (MGDN) de una mezcla acuosa que comprende MGDN. El método comprende enfriar la mezcla acuosa en uno o más pasos. En uno de estos pasos, la mezcla se enfría a una velocidad de enfriamiento de por lo menos 20 K/h desde una temperatura arriba del punto de solidificación de MGDN a una temperatura debajo del punto de solidificación de MGDN. El método es implementado continuamente.
