Product Description

Potassium Persulfate with CAS 7727-21-1

Potassium Persulphate(CAS:7727-21-1), is inorganic compound, white crystal, odourless, hydrolytic. Potassium Persulphate helps to burn and is stimulating. Potassium Persulphate is mainly used as bleaching agent, strong oxidizer, photographic medicine, analytical reagent, polymerization promoter, etc. And it can be used for vinyl acetate, acrylic ester, acrylonitrile, styrene, vinyl chloride monomer emulsion polymerization initiator (using temperature 60 ~ 85 ℃), and synthetic resin polymerization accelerator.

Use:
1. Mainly used as disinfectant and fabric bleaching agent;
2. Used for vinyl acetate, acrylic ester, acrylonitrile, styrene, vinyl chloride monomer emulsion polymerization initiator (using temperature 60 ~ 85 ℃), and synthetic resin polymerization accelerator;
3. Used as glue breaking agent for fracturing fluid of oil well. As the initiator of emulsion polymerization in synthetic resin and synthetic rubber industry, it is used for the synthesis of butadiene styrene rubber.
4. Potassium persulphate is the intermediate of hydrogen peroxide by electrolysis, which is decomposed into hydrogen peroxide.
5. Potassium persulphate is used for etching and coarsening of copper in oxidizing solution of steel and alloy, as well as for impurities in solution.
6. Used as an analytical reagent and as an oxidant and initiator in chemical production. Also used for film printing, as sodium thiosulphate removal agents.
