A method for isolating methylglycinenitrile-N,N-diacetonitrile (MGDN) from an aqueous mixture comprising MGDN is provided The method comprises cooling the aqueous mixture in one or more steps In one of these steps the mixture is cooled at a cooling rate of at least 20K/h from a temperature above the solidification point of MGDN to a temperature below the solidification point of MGDN The method is implemented continuously
提供了一种从含有甲基甘
氨酰亚
硝基胺-N,N-二
乙腈(MGDN)的
水溶液中分离MGDN的方法。该方法包括在一个或多个步骤中冷却
水溶液混合物。在其中一个步骤中,混合物以至少20K/h的冷却速率从高于MGDN凝固点的温度冷却到低于MGDN凝固点的温度。该方法是连续实施的。
