monoamidemononitrile-malonicaci - Preparation Method
Open Data Verified Data
can be prepared from ethyl cyanoacetate and ammonia. The ethyl cyanoacetate was cooled to below 200 ℃, and concentrated ammonia water was added for reaction to obtain the mixture was changed from turbidity to clear. After cooling in cold water for 20 minutes, precipitation was precipitated, and the crude product was obtained after filtration and spin drying, then add the crude cyanoacetamide
In the boiling ethanol, after it is dissolved, a small amount of activated carbon is added, decolorized and refined, filtered, the filtrate is cooled and precipitated, and dried at 80-100 ° C. To obtain cyanoacetamide fine product.
