As an online chemical trading market, we are supposed to offer helpful information about Urea suppliers that could help urea traders to find trustful suppliers. So here we introduce some of the best Urea suppliers: and some other tips that could help you to buy and sell Urea safer.
First notice that Urea is also called carbamide. It is rich in nitrogen, so it is a good choice for producing livestock supplements. It is soluble in water and does not cause any harm.

Urea Buying Guide
It is important for most customers to buy industrial chemicals that provide quality products at competitive prices. This is also true of carbamide purchases. In this section, we will be familiar with the purchase guide and physical and chemical characteristics.
Product Quality
This compound is sold in the form of a white solid color. When shopping, make sure the bags are completely sealed. Any color change in this material can indicate that it is inferior. Carbamide is high quality, white and free of any bad smell.
Physical and chemical properties of urea
The chemical formula of carbamide is CH4N2O. It is solid and white and odorless. It is soluble in compounds such as ethanol, acetonitrile, glycerol in certain amounts. The most important compound similar to this material is called thiourea.

Urea Manufacturing Methods
1-Industrial production of CH4N2O
In factories, carbamide is a product made from ammonia and carbon dioxide. In the vicinity of ammonia plants, an industrial carbamide manufacturing plant is also expected to be operating.
2- Synthetic production of carbamide
This synthetic method was first invented in 1922. This compound is formed in several processes of reactions. These reactions are below.
2 NH3 + CO2 ⇌ H2N-COONH4
ΔH = -117kJ / mol (at 110 atmospheres and 160 degrees Celsius)
H2N-COONH4 ⇌ (NH2) 2CO + H2O
ΔH = +15.5 kJ / mol (at 160-180 degrees Celsius)
3-Laboratory production method
These reactions are below.
COCl2 +4 RNH2 → (RNH) 2CO +2 RNH3Cl
NH4OCN → (NH2) 2CO
Urea usages

| Other uses of urea | Production of teeth whitening products - an additive in the color bath - use as an additive in a fire extinguisher - as antifreeze |
Urea packaging and storage
Urea is offered in 50kg and 1000kg bags. Transportation of bags should be safely.
Maintenance, Loading and Delivery
Loading and maintenance of carbamide is carried out according to standard procedures. This material should be stored in dry and cool warehouses, with full ventilation and away from incompatible materials (oxidizing compounds, chlorinated materials).
Urea Safety Tips
Dust from this substance can irritate it by entering the respiratory system. Swallowing this substance causes nausea or digestive problems. Carbamide is chemically stable. It is better for people who are dealing with this material to wear safety work clothes, masks, glasses and gloves.
Competitive price to buy urea
Carbamide is used for chemical fertilizer production and then for animal feed. This material is offered in various quantity for consumer industries. You can buy high quality carbamide directly from suppliers through the Shimico website.
who invented urea?
urea is an organic compound that is the main nitrogen-containing substance in the urine of mammals. The French chemist Hilaire-Marin Rouelle isolated it from urine for the first time in 1773. It was first synthesized from inorganic materials in 1828 by the German chemist Friedrich Wöhler, which was a landmark achievement in chemistry. Wöhler was able to produce carbamide through two combinations of silver cyanate and ammonium chloride. The chemical formula of this compound is shown as CO(NH2)2.
