Use

Biuret is the resulting product in urea production process by deamination and condensation reaction when the temperature is higher than the melting point of urea (150-170 ℃). Formula is NH2CONHCONH2. Reaction is as follows NH2CONH2-(heating)- HNCO + NH3, HNCO + NH2CONH2 NH2CONHCONH2, crystallization of urea in the granulation process will generate biuret, this substance is toxic to plants, thus content of biuret in urea is required not exceed 1%. Top dressing with urea, the content of biuret should not exceed 0.5%.
