Specification  :

Urea or carbamide is an organic compound with the chemical formula CO(NH2)2. The molecule has two amide (—NH2) groups joined by a carbonyl (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 solid, colourless, and odorless (although the ammonia which it gives off in the presence of water, including water vapor in the air, has a strong odor). It is highly soluble in water and non-toxic. Dissolved in water it is neither acidic nor alkaline. The body uses it in many processes, most notably 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. The synthesis of this organic compound by Friedrich Wöhler in 1828 from an inorganic precursor was an important milestone in the development of organic chemistry, as it showed for the first time that a molecule found in living organisms could be synthesized in the lab without biological starting materials.

The terms urea and carbamide are also used for a class of chemical compounds sharing the same functional group RR'N—CO—NRR', namely a carbonyl group attached to two organic amine residues. Examples include carbamide peroxide, allantoin, and hydantoin. Ureas are closely related to biurets and related in structure to amides, carbamates, carbodiimides, and thiocarbamides

Beijing Jin Coal Sun Stone Limited Company (or Jin Coal Sun Stone for short) is a professional sale company which primarily produces Urea, phosphatic fertilizer, compound fertilizer, methyl alcohol and other chemical industry and fertilizer products. It is established in August 2009. Shanxi Jin Cheng blind coal group limited company (or Jin Coal Group for short) and other 20 chemical industry companies contributed to establish the Sun Stone Corporation by funding 266 million RMB as register capital. It’s the coal chemical industry sales Company of the Jin Coal Group. Our company is located in Daxing District of Beijing Economic and Technological Development Zone. It consists of seven functional departments, 19 branches and 1 subsidiary, with 34 registered people currently.

Jin Coal Sun Stone Company is responsible for the sales of fertilizers and chemical products such as urea, ammonium carbonate, compound fertilizer, ammonium nitrate, MAP(mono ammonium phosphate), DAP(diammonium phosphate), slow-released granular urea produced by chemical subsidiaries of Jin Coal Group. At present, the company has 18 core suppliers and 58 production plants, widely distributed in 10 provinces including Shanxi, Hebei, Henan, Shandong, Jiangsu, Anhui, Hunan, Hubei, Zhejiang and Xinjiang. As the company continues to grow, our company will gradually expand the sales of fine chemical products during the mid to late stages of 12th Five-year Plan.
