Usage areas of Sodium persulfate

Sodium persulfate is also known as sodium peroxydisulfate; White crystal or crystalline powder, odorless, tasteless. The formula is Na2S208, relative molecular mass is 238.13. Slow decomposition at room temperature, heating in ethanol or rapidly decomposing, decomposing to release oxygen and producing sodium pyrosulphate. Moisture and platinum black, silver, lead, iron, copper, magnesium, nickel, manganese and other metal ions or their alloys can accelerate decomposition and emit hydrogen peroxide at high temperature (about 200 ° C). It is soluble in water (70°C at 20°C). It has strong oxidizing properties. There is a strong irritation to the skin, prolonged contact with the skin can cause allergies, should pay attention during surgery.

Usage areas

• In the polymerization of acrylonitrile, often in the production of polyacrylonitrile fibers with alkaline sulfides, in the emulsion polymerization of monomers.
• As an oxidant in the textile industry.
• In the oxidation of sulfur dyes.
• Metal, photography, cosmetics industries.
• In the production of various chemicals.

Sodium persulfate is a strongly oxidizing chemical used as a bleaching and oxidizing agent. Persulfate oxidation mechanisms are effective in degrading many volatile oxidizing chemicals (VOCs) including chlorinated ethenes (CEs), BTEXs and trichloroethanes. The compound is used as a promoter for polymerization reactions. Sodium persulfate has also been used as a chemical oxidant to treat laboratory slurry reactors for the accumulation of surfactants.

Sodium Persulfate is used as a promoter for polymerization reactions.
