Urea 46

Urea or carbamide is an organic compound with the chemical formula CO(NH2)2. The molecule has two —NH2 groups joined by acarbonyl (C=O) functional group.

Urea serves an important role in the metabolism of nitrogen-containing compounds by animals and is the main nitrogen-containing substance in the urine of mammals. It is a colorless, odorless solid, highly soluble in water and practically non-toxic. Dissolved in water, it is neither acidic nor alkaline. The body uses it in many processes, the most notable one being nitrogen excretion. Urea is widely used in fertilizers as a convenient source of nitrogen. Urea is also an important raw material for the chemical industry.

CHEMICAL FORMULA FOR UREA:

 

CO(NH2)2 or NH2CONH2

 

Urea is made by reacting carbon dioxide (CO2) with anhydrous ammonia (NH3) under pressure of 3000 psi and temperatures of around 350 deg F. Water is removed during processing and the molten matter is either converted to prills or into granules.

 

SHAPE OF UREA:

 

It is generally supplied in prills or crystals/grains. Although the colour of urea is white but the crystals are larger than prills.

 

 PACKING OF UREA:

 

Commercial Urea is available in any desired packing. However it is generally packed in 50 kg bags or bulk/loose, 25 kg/ wpp bag,1000 kg

 

COUNTRY OF ORIGIN FOR UREA:

 

Urea is produced in several countries, some major producers are:

China,India,Indonesia ,Iran,Italy,Pakistan,Russia,Ukraine,Saudi Arabia
