Ammonium persulfate

Molecular Formula: (NH4)2S2O8

Molecular weight: 228.2


Physicochemical properties: Ammonium persulfate is a white single crystal, density 1.98, completely decomposed at 120 °C, completely dry and can not be decomposed for long-term storage, not suitable for moisture absorption, but gradually releases oxygen and ozone after absorbing moisture. Dissolved in water and decomposed by heat. It has strong oxidizing property and can be used as chemical reagent, oxidant, bleach, deodorant, monomer polymerization initiator. It also has the advantages of ease of use and safety.

Storage: Ammonium persulfate is not a flammable product, but it can help combustion because it can release oxygen. When it is stored, it must be stored in a dry, airtight container to avoid direct sunlight and heat source. Do not contact with reducing substances such as organic substances, rust, and small amounts of metals to prevent decomposition and explosion of ammonium persulfate. Because the moist ammonium persulfate powder and its aqueous solution are bleached and slightly corroded, the eyes, skin, and clothing are kept in direct contact with it during use.



Polymerization: Initiator of latex or acrylic monomer polymerization solution, initiator of ethyl acetate, ethylene chloride, vinyl chloride and other products. It is also an initiator of copolymerization of styrene acrylonitrile, butadiene and other colloids.

Metal treatment: Treatment of metal surfaces (eg in semiconductor manufacturing: cleaning and etching of printed circuits). Activation of copper and aluminum surfaces.

Cosmetics: The main ingredient in bleaching formulas.

Textiles: De-slurry and bleach - especially for low-temperature bleaching.

Others: Chemical synthesis: Water treatment (purification); Disinfectant; Exhaust gas treatment, oxidative degradation of harmful substances (eg mercury); Paper (starch modification, special repulping for low-temperature bleaching).
