Urea, also known as urea or carbon amide, has a chemical formula of CH4N2O or CO(NH2)2 . It is an organic compound composed of carbon, nitrogen, oxygen, and hydrogen. It is a white crystal. One of the simplest organic compounds, it is the major nitrogen-containing end product of protein metabolism in mammals and some fish.
As a neutral fertilizer, urea is suitable for a variety of soils and plants. It is easy to store, convenient to use, and has little damage to the soil. It is a chemical nitrogen fertilizer that is used in large quantities and is also the nitrogen fertilizer with the highest nitrogen content. Industrially, ammonia and carbon dioxide are used to synthesize urea under certain conditions.
1. It can be used as a large amount of raw materials for the production of melamine, urea-formaldehyde resin, hydrazine hydrate, tetracycline, phenobarbital, caffeine, reduced brown BR, phthalocyanine blue B, phthalocyanine blue Bx, MSG and other products.
2. It has a brightening effect on chemical polishing of steel and stainless steel. It is used as a corrosion inhibitor in metal pickling and is also used in the preparation of palladium activation solution.
3. Selective reducing agent for combustion exhaust gas denitration, and vehicle urea, which consists of 32.5% high-purity urea and 67.5% deionized water.
4. Selective catalytic reduction (SCR) exhaust after-treatment is a technology that uses the ammonia produced by the pyrolysis reaction of urea in the combustion exhaust to selectively catalytically reduce nitrogen oxides (NOx) in the vehicle exhaust. , is a key and mainstream technology for reducing NOx, a harmful substance in combustion exhaust gases such as combustion boilers and diesel engines.
5. Raw materials of special plastics, especially urea-formaldehyde resin, raw materials of certain glues, ingredients of fertilizers and feeds, which replace antifreeze salt and spread on the streets (the advantage is that it does not cause metal corrosion), enhance the smell of cigarettes, and give industrial production Pretzel brown, ingredients in some shampoos and detergents, ingredients in first-aid refrigeration packs (because the reaction between urea and water absorbs heat), vehicle urea treatment of exhaust gases from diesel engines, engines, thermal power plants, especially Reduce its nitrogen oxides, components of rainfall agents (compound salts), used to separate paraffin (because urea can form clathrates), refractory materials, components of environmentally friendly engine fuel, components of tooth whitening products, chemical fertilizers, dyes and An important auxiliary when printing.
