Nitrogen fertilizer classification urea
Product Description
Urea is an organic compound composed of carbon, nitrogen, oxygen and hydrogen,
also known as urea (same as urine). The international generic drug name is Carbamide. The appearance is white crystal or powder. It is a product of animal protein metabolism and is commonly used as a nitrogen fertilizer for plants. Urea is synthesized in the liver and is a nitrogen-containing metabolite excreted in mammals. This metabolic process is called the urea cycle. Urea is the first organic compound obtained by artificially synthesizing inorganic substances.

Urea chemical formula: CO (NH2) 2, molecular mass 60.06, CO (NH2) 2 colorless or white needle or rod crystal, industrial or agricultural products are white with slightly reddish solid particles, odorless and tasteless. The nitrogen content is about 46.67%. The density is 1.335 g/cm3. The temperature of 132.7 ° C. Soluble in water, alcohol, insoluble in ether, chloroform. It is weakly alkaline. It can react with acid to form a salt. 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 while changing to cyanic acid. Because it contains this substance in human urine, it is named urea. Urea contains 46% nitrogen (N), which is the highest nitrogen content in solid nitrogen fertilizer.
Usage
Application fields
1. Medical applications: Dermatology uses certain agents containing urea to increase the humidity of the skin. The occlusive dressing used for non-surgical removal of nails contains 40% urea.
2. Agricultural application: Urea is a high-concentration nitrogen fertilizer, which is a neutral quick-acting fertilizer and can also be used to produce a variety of compound fertilizers. No harmful substances remain in the soil, and long-term application has no adverse effects. Urea is an organic nitrogen fertilizer that can be absorbed and utilized by crops after being hydrolyzed to ammonium carbonate or ammonium hydrogencarbonate by urease in the soil.
3. Commercial application: special plastic raw materials, especially urea formaldehyde resin; some rubber raw materials; fertilizer and feed ingredients; instead of anti-freezing salt scattered in the street, the advantage is not to corrode the metal; strengthen the smell of cigarettes;
4. Laboratory application: Urea is very effective in denaturation of proteins, especially in the destruction of non-covalently bound proteins. This feature can increase the solubility of certain proteins at concentrations up to 10 moles/vol. Urea can also be used to make urea nitrate.
5. Application in cosmetics: Urea is a very good moisturizing ingredient. It is found in the stratum corneum of the skin and belongs to the main component of the skin's natural moisturizing factor NMF. For the skin, urea has moisturizing and soft keratin, so it can prevent the cuticle from blocking the pores, thereby improving the problem of acne.
6. Industrial application: It has a light-increasing effect on chemical polishing of steel and stainless steel, as a corrosion inhibitor in metal pickling, and also used in the preparation of palladium activation liquid.
