QINGDAO, China

We offer urea. prilled and granular, n46, 50kg or big bags urea cas no.: 57-13-6 molecular formula: ch4n2o molecular weight: 60.06 structural formula: properties: 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. Urea is solid, colorless, and odorless (although the ammonia that it gives off in the presence of water, including water vapor in the air, has a strong odor). Urea is highly soluble in water and practically non-toxic (ld50 is 15 gkg for rat). Dissolved in water, it is neither acidic nor alkaline. The body uses urea in many processes, the most notable one being 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.

Ammonium sulphate has ph value is 5.5 in 0.1m solution. Density 1.769 gcm3 (20°c). Ammonium sulphate is hygroscopic; soluble in water; insoluble in acetone, alcohol and ether. Main active ingredients are 21% nitrogen and 24% sulfur, so it can be described as npk 21-0-0 24s. Generally, it is a by-product from chemical (cyanuric acid, capro, acrylonitrile, sodium cyanide, monosodium glutamate-msg, methyl methacrylate-mma, etc.) or steel plant. Steel grade (also call coke-ovens grade) is fine white powder. After processing it can be white granular or flake. Caprolactam grade is colorless (achromatic) crystalline or yellowish crystals.

Ammonium sulphate is the best fast release, quick acting fertilizer, which can be directly used for a variety of soil and crops. It can also be used as kinds of seed fertilizers, base fertilizer and additional fertilizer. It is particularly suitable for the soil which lack of sulfur, low chlorine tolerance crops, sulfur-philic crops. Ammonium sulphate is very popular in japan, southeast asia, as well as northeast china where plant premium rice. It is suitable for the rice seedling, the growth of tea, grass, vegetables, and fruit trees, effectually rapid promoting the growth of grain, vegetables, fruits, grass and other plants. It has more efficiency than urea, ammonium b
