Sodium persulfate
Molecular formula: Na2S2O8
Molecular Weight: 238.13
Physicochemical properties: Sodium persulfate is a white colorless and odorless crystal, or powder, with a density of 2.4g/cm3, decomposed by ethanol, and has good stability at room temperature. It is often used as a strong oxidizing agent, and can also be used as a monomer polymerization initiator, which almost does not absorb moisture, is easy to store, and is convenient and safe to use.
Storage: Sodium persulfate is a non-flammable product, but because it can release oxygen and has a combustible effect, it must be stored in a dry, closed container, away from direct sunlight and heat sources. Do not come into contact with organic matter, rust, a small amount of metal and other reducing substances to prevent the decomposition and explosion of sodium persulfate. Because the moist Sodium persulfate powder and its aqueous solution have a bleaching and slightly corrosive effect, avoid direct contact with eyes, skin and clothing during use.
Uses:
Polymerization: Initiator of latex or acrylic monomer polymerization solution, acetate ethyl combustion, vinyl chloride and other products, and also an initiator for the copolymerization of styrene acrylonitrile, butadiene and other colloids.
Metal treatment: Treatment of metal surfaces (e.g. in semiconductor manufacturing: cleaning and etching of printed circuits). Activation of copper and aluminum surfaces.
Cosmetics: The main ingredient in bleaching formulas.
Textiles: desizing agents and bleaching agents – especially for low-temperature bleaching.
Other: Chemical Synthesis: Water Treatment (Purification), Disinfectants, Waste Gas Treatment, Oxidative Degradation of Hazardous Substances (e.g. Mercury).
