Ammonium sulfate CAS#7783-20-2
Ammonium sulfate (AS) is the earliest production and use of nitrogen fertilizer. It is usually used as a standard nitrogen fertilizer, nitrogen content is between 20% to 30%. It is a very important fertilizer for any kind of soil that's high in pH and needs a little bit of sulfates to work against the high calcium or the high pH. The nice thing about the ammonium sulfate is that the nitrogen in it is a little bit slower releasing so it lasts throughout the growing season better than the nitrate forms of nitrogen.
In the 1960s, Ammonium sulfate is the main variety of nitrogen fertilizer, but also is a major source to provide crop nutrients sulfur. Firstly ammonia and sulfuric acid was neutralized to obtain, but later increasing proportion of by-product ammonium sulfate, and now Ammonium sulfate is actually produced as a by-product in many industrial processes including the manufacturing of steel, coking industry, caprolactam, sulfuric acid tail gas desulfurization, desulfurization of power plant, acrylonitrile and methyl methacrylate, zinc oxide and some polyester compounds.
Pure product of ammonium sulfate is white crystals, heated to 100 ℃ , began to be decomposed into ammonia and ammonium bisulfate, a by-product with a yellowish or gray, small moisture absorption, easy to agglomerate, it is easier to save and easily soluble in water, insoluble ethanol and acetone.
Ammonium sulfate serves as physiological acidic nitrogen fertilizer, is generally more suitable for wheat, corn, rice, cotton, potato, hemp, fruit trees, vegetables and other crops. For soils, the ammonium sulfate is most suitable for neutral soil and alkaline soil, but not suitable for acidic soil. Also used as analytical reagents (precipitating agent, masking agent), in electrochemical analysis, supports electrolyte, microbiological culture media and preparation of ammonium salts.
