Method for separating methylglycinenitrile-N, N-diacetonitrile from aqueous crude mixture |
| abstract |
The present invention relates to a process for separating MGDN in a crystallizer from an aqueous emulsion containing MGDN having a content of methylglycinenitrile-N, N-diacetonitrile (MGDN) of 3-50% by weight. The process of the present invention comprises the steps of (a) cooling the aqueous emulsion to a temperature below the freezing point until the entire emulsified MGDN is substantially solidified, wherein the average cooling rate over time is 5 Not exceeding K / h, and (b) further cooling and / or concentrating the resulting aqueous suspension and allowing the cooling rate to be greater than the cooling rate of step (a). . |
