CAS·:57-13-6 Urea for vehicles, agricultural urea, urea N46
When the temperature of urea is below 20 and the relative humidity is below 70%, it will not only not absorb moisture, but also evaporate water and reduce its water content; When the temperature exceeds 20 �¢?? and the relative humidity is higher than 80%, it starts to absorb moisture, and becomes paste when it is serious. When the air is dried again, it will re agglomerate, which is only inferior to ammonium nitrate. When the urea aqueous solution is at 80 �¢??, hydrolysis and decomposition reactions will occur, forming ammonium carbamate, ammonia gas and carbon dioxide respectively. Under acid and alkaline conditions, urea will decompose faster when it is heated. Urea is easy to combine with straight chain carbohydrates to form crystalline additional compounds; It forms a variety of double salts with various inorganic compounds, such as Ca (NO3) 2 �?�· 4CO (NH2) 2, NH4Cl �?�· CO (NH2) 2, CaChemicalbookSO4 �?�· 4CO (NH2) 2, MgSO4 �?�· 4CO (NH2) 2 �?�· 3H2O, Mg (NO3) �?�· 4CO (NH2) 2 �?�· 2H2O, etc; It is easy to form urea phosphate, dicalcium phosphate and water with monocalcium phosphate, namely Ca (H2PO4) 2 �?�· H2O+CO (NH2) 2 �¢?? H3PO4 �?�· CO (NH2) 2+CaHPO4+H2O; With nitric acid, it is easy to form urea nitrate, CO (NH2) 2+HNO3 �¢?? CO (NH2) 2 �?�· HNO3, which combines and relaxes the two; It can combine with formaldehyde to form urea formaldehyde compounds (uric acid rubber shrinks), in which the higher proportion of formaldehyde is urea resin, and the lower proportion is slow-release (effective) urea.

Supplier From Ontario, Canada
 
Urea, a nitrogen-rich compound with the chemical formula CO(NH), plays a significant role in the oil and gas industry, Urea, also known as carbamide, is a highly soluble organic compound. It is synthesized on a large scale from ammonia and carbon dioxide and is primarily used in fertilizers, which accounts for about 90% of its global production.

Chemical Properties
Molecular Formula: CO(NH)
Molar Mass: 60.06 g/mol
Appearance: White, crystalline solid
Melting Point: 133C (271F)
Solubility: Highly soluble in water, forming a neutral solution
Industrial Production
The production of urea typically involves the following steps:

Ammonia Production: Sourced primarily from natural gas (methane) through the Haber-Bosch process.
Reaction with Carbon Dioxide: Ammonia reacts with carbon dioxide to produce ammonium carbamate, which is then dehydrated to form urea and water:2 3 2+ 2NH 3 +CO 2 NH 2 CONH 2 +H 2 O

Diesel Exhaust Fluid (DEF): Urea is used to reduce nitrogen oxide (NOx) emissions from diesel engines. DEF, a mixture of 32.5% urea and 67.5% deionized water, is injected into the exhaust stream of diesel engines.
Oil Drilling Fluids: Urea can be used in drilling mud formulations to enhance the efficiency of the drilling process.
Chemical Manufacturing: Urea serves as a feedstock in the production of various chemicals such as melamine and urea-formaldehyde resins.
Desulfurization: It is used in processes to remove sulfur compounds from petroleum products.
Market Dynamics
Demand: The demand for urea is largely driven by its use in agriculture. However, industrial uses, including those related to the oil and gas sector, contribute significantly to its market.

Pricing: Urea prices are influenced by the cost of natural gas, the primary raw material, and global agricultural demand cycles and NEGOTIABLE

Environmental Impact: While urea itself is not hazardous, its overuse in agriculture can lead to environmental issues such as eutrophication.

Handling and Storage: Urea should be stored in a cool, dry place away from moisture, as it is highly hygroscopic. It is considered non-toxic, but proper safety measures should be followed to avoid dust inhalation or skin contact.

Logistics: Efficient transportation and storage solutions are vital to maintain urea quality and manage costs.
Regulations: Compliance with international and local regulations regarding chemical handling, safety, and environmental impact is crucial.
Market Opportunities: Identifying and targeting markets with growing industrial and agricultural demand for urea can enhance profitability.

Origin: Russia/ Kazakhstan.

CHEMICAL INDUSTRY
Urea is a raw material forthe manufacture of twomain classes of materials:urea-formaldehyde resins and urea-melamine-formaldehyde used in marineplywood.

AGRICULTURE
More than 9O% of world industrial production of urea is destined for useas a nitrogen-release fertilizer.
Urea has the highest nitrogen con-tent of all solid nitrogenous fertilizersin common use.
Therefore, it has the lowest transpor-tation costs per unit of nitrogen nutri-ent.

Urea is a small diameter, spherical white solid. It is an organic amide molecule containing 46% nitrogen in the form of amine groups. UREA is infinitely soluble in water and is suitable for use as an agricultural and forestry fertilizer as well as for industrial applications which require a high quality nitrogen source.

Applications

1.Medical field
Dermatology uses certain agents containing urea to increase the humidity of the skin. Non-surgical removal of nails uses occlusive dressings that contain 40% urea.
2.Agriculture
Urea is a highly concentrated nitrogen fertilizer, which is a neutral fast-acting fertilizer, and can also be used to produce a variety of compound fertilizers. No harmful substances remain in the soil, and there are no adverse effects after long-term application. Animal husbandry can be used as feed for ruminants. However, if the temperature is too high in granulation, a small amount of biuret will be produced, also known as biuret, which has an inhibitory effect on crops. China stipulates that the content of urea biuret for fertilizer should be less than 0.5%. When the content of biuret is more than 1%, it can not be used as seed fertilizer, seedling fertilizer and foliar fertilizer, and the urea content in other application periods should not be too much or too concentrated.
3.Industrial sector
It can be used in large quantities as a raw material for the production of melamine, urea-formaldehyde resin, hydrazine hydrate, tetracycline, caffeine, reduced brown BR, phthalocyanine blue B, phthalocyanine blue Bx, monosodium glutamate and other products.
4.Laboratory applications
Urea is very effective at denaturing proteins, especially non-covalently bonded proteins. This feature can improve the solubility of certain proteins at concentrations of up to 10 mol/volume. Urea can also be used to make urea nitrate.
