Use | Organic synthesis intermediate |
production method | under the condition of stirring and maintaining 0 ℃, add sodium cyanide aqueous solution to the mixture of formaldehyde and ammonium chloride, add glacial acetic acid dropwise in the middle of feeding. After adding, stirring for 1.5h, the precipitate is filtered out, washed with water and dried to obtain methylene amino acetonitrile with a yield of 61-71%. |
