Chemical properties

It can form a salt with an acid and has hydrolysis. The condensation reaction can be carried out at a high temperature to form a biuret, a triuret and a cyanuric acid. It is decomposed by heating to 160 ° C to produce ammonia gas and become isocyanic acid. Because it contains this substance in human urine, it is named urea. Urea contains 46% nitrogen , which is the highest nitrogen content in solid nitrogen fertilizer. Urea can be hydrolyzed to form ammonia and carbon dioxide under the action of acid, alkali and enzyme (acid and alkali need to be heated). It is unstable to heat and will be deaminated to biuret when heated to 150~160 °C. The reaction between copper sulfate and biuret is purple and can be used to identify urea.
