METHOD FOR ISOLATING METHYLGLYCINENITRILE-N,N-DIACETONITRILE

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 20 K/h from a temperature above the solidification point of MGDN to a temperature below the solidification point of MGDN The method is implemented continuously

METHOD FOR ISOLATING METHYL GLYCINE NITRILE-N,N-DIACETONITRILES FROM AN AQUEOUS CRUDE MIXTURE

The invention relates to a method for isolating methyl glycine nitrile-N,N-diacetonitriles (MGDN) from an MGDN-containing aqueous emulsion with an MGDN content of 3 - 50% by weight in a crystallizer. The inventive method is characterized by (a) cooling the aqueous emulsion, starting from a temperature above the solidification point, to a temperature below the solidification point, the cooling rate in the temporal mean not exceeding 5 K/h, until substantially the total amount of the emulsified MGDN has solidified; and (b) continuing to cool the aqueous suspension obtained and/or concentrating it, the cooling rate being higher than that in step (a).
