production method | was prepared by heating formylhydrazide. The formyl hydrazine is heated for 3H under normal pressure, the bath temperature is increased from 50 ℃ to 200 ℃, then cooled to about 100 ℃, and the syrup is dissolved in 95% ethanol, and then activated carbon is added to decolorize, the filtrate was then diluted with diethyl ether, cooled to crystallize, and filtered. The crude product was washed with a 1:2 ethanol-ether mixed solvent and dried, and recrystallized from 95% hot ethanol and ether to give a pure product. Carbohydrazide can be obtained from the reaction of ethyl formate and hydrazine hydrate. |
