Petro chemical
Basic Information
English name: Ammonium Sulfate. Molecular weight: 132.14 g/mol. EINECS No. (EU chemical number): 231-984-1. When preparing international trade documents (such as Proforma Invoice, Sales Contract), safety data sheets (SDS/MSDS) or customs declarations, be sure to identify CAS No. 7783-20-2 to ensure compliance and uniqueness of chemical identification.
Main Application Fields
1. Agriculture (High-efficiency Fast-acting Fertilizer)
-
Nitrogen and sulfur supplementation: ammonium sulfate contains up to 21% ammoniacal nitrogen (NH4+) and 24% sulfur (S). Ammoniacal nitrogen can be directly absorbed by plant roots and, compared with nitrate nitrogen, is less prone to leaching in the soil; sulfur is a core element for synthesizing essential amino acids (such as cysteine and methionine) in plants.
-
Improving alkaline soil: ammonium sulfate is a physiologically acidic fertilizer. Long-term application to alkaline or calcareous soils helps gradually lower the soil pH, thereby activating fixed trace elements such as phosphorus, iron and manganese in the soil and improving crop uptake.
-
Suitable crops: especially suitable for sulfur-loving crops (such as tea, garlic, onion and rapeseed) and chlorine-sensitive crops that avoid chlorine.
2. Industrial and Biochemical Fields
-
Biomedicine (protein purification): widely used in biochemical research and the pharmaceutical industry via the ammonium sulfate precipitation method. The salting-out effect of high-concentration ammonium sulfate disrupts the hydration film on the protein surface, causing specific proteins to precipitate; this process does not easily damage the biological activity of proteins.
-
Textile and leather industries: in textile dyeing, used as a dyeing auxiliary or retarding agent for acid dyes to control the dyeing speed and uniformity. In the leather industry, used as a deliming agent to neutralize the alkaline substances remaining after unhairing.
-
Water treatment and other applications: used as a chloramination agent in drinking water treatment, reacting with chlorine to form chloramines that provide longer-lasting disinfection in the pipe network than free chlorine. Used as an industrial base raw material for manufacturing other ammonium salts (such as ammonium chloride and compound fertilizers). Also serves as a flame-retardant component in refractory materials and wood processing.
