Potassium persulfate CAS 7727-21-1


Potassium persulfate is a white, odourless crystal, soluble in water, insoluble in ethanol, with strong oxidative properties, commonly used as bleach, oxidant, can also be used as a polymerisation reaction initiator, almost non-hygroscopic, stable at room temperature, easy to store, and has the advantages of convenience and safety. Application areas involve polymerisation reaction Chemicalbook should be used as initiator, circuit board cleaning and etching, copper and aluminium surface activation, starch modification, low-temperature bleaching and desizing of pulp and fabrics, purification of circulating water system, oxidative degradation of hazardous gases, acceleration of low formaldehyde adhesive bonding, oxidation of ethanol and aromatic hydrocarbons, disinfectant, decolourisation of hair dyes, and so on.

1.Performance and use

Potassium persulfate is mainly used as initiator and strong oxidising agent

Initiator: Potassium persulfate is the initiator of latex or acrylic monomer polymerisation solution, vinyl acetate, vinyl chloride and other products, as well as the initiator of copolymerisation of styrene, acrylonitrile, butadiene and other colloids.

Strong oxidising agent: (1) Used as desizing agent and bleaching active agent. (2)Used for oxidative degradation of harmful substances in pools and closed-cycle treatment water. (3)It is a regulator for the production of starch and is used in the production of adhesives and coatings. (4) It is used in branched chain oxidation, ethanol and aromatic hydroxyl oxidation. (5) It is one of the basic components of hair dyes and acts as a decolourising agent.
