what is the reaction with urea?
i search how urea reacted with and what is the condition, by- product produced...etc...more particularly the reaction with nitrous acid (HNO2) and
hypobromite...i know for the reaction with nitrous acid, we should be in acid solution and urea should be in excess...but it's all...if you are more
information for me...(temperature...). For the reaction with hypobromite (or hypochlorite) i don't know what is the condition to make the reaction...i
just know that:
CO(NH2)2 + 3 NaOBr --> N2 + CO2 + 3NaBr +2 H2O
thank's a lot and scuse for me english...(im french..)

I don't know why this is in this section. But NaBrO reacts quicker with urea than NaClO at regular temperatures, and its over after a few seconds,
even with low BrO- concentration. 90% of the urea is decomposed: (NH2)2CO + 3 NaBrO = 3 NaBr + 2 H2O + CO2 + N2, the rest is undecomposed. Excess urea
reacts with NaBrO to NaHCOO and NaNCO (Gmelin C [D1] 420-421).
