Malonamide is used to synthesize malonic acid, malonic acid ester and malonic amide derivatives of some active heterocyclic compounds. Chemical property: white monoclinic acicular crystal. Melting point 170 ℃ (171.5-172.5 ℃). The solubility in water at 8 ℃ is 8.3g/100ml, insoluble in alcohol, ether and benzene. Use: for organic synthesis. Uses It is mainly used as raw material for organic synthesis. The production method is obtained from the reaction of diethyl malonate and ammonia. Add ammonia water into the enamel barrel, cool it to below 25 ℃, slowly add diethyl malonate under stirring, and the reaction temperature is about 20 ℃. After the reaction, place it at room temperature for two days. Filter out the crystal at the bottom, concentrate under reduced pressure, add decoloring carbon, filter through suction, cool and crystallize, dry at 80 ℃, and crush to be the finished product.
