WebThe urea solution can be used as an ingredient of nitrogen solution fertilizers, or it can be concentrated further to produce solid urea. The 3 methods of concentrating the urea solution are vacuum concentration, crystallization, and atmospheric evaporation. The method chosen depends upon the level of biuret (NH2CONHCONH2)
Ureas describes a class of chemical compounds that share the same functional group, a carbonyl group attached to two organic amine residues: R R N−C(=O)−NR R , where R , R , R and R groups are hydrogen (–H), organyl or other groups. Examples include carbamide peroxide, allantoin, and hydantoin. Ureas are closely related to biurets and related in structure to amides, carbamates, carbodiimides, and thiocarbamides.
