Sodium persulfate is the inorganic compound with the formula Na₂S₂O₈. It is the sodium salt of persulfate (also called peroxydisulfate), an oxidizer. It is a white solid that dissolves in water. It is almost non-hygroscopic and has good shelf-life.

Detailed description

Applications

It is mainly used as a radical initiator for emulsion polymerization reactions for styrene based polymers such as Acrylonitrile butadiene styrene.^[3] Also applicable for accelerated curing of low formaldehyde adhesives.

Other uses

It is a bleach, both standalone (particularly in hair cosmetics) and as a detergent component. It is a replacement for ammonium persulfate in etching mixtures for zinc and printed circuit boards, and is used for pickling of copper and some other metals.

It is also used as a soil conditioner and soil remediation and in manufacture of dyestuffs, modification of starch, bleach activator, desizing agent for oxidative desizing, etc.

Organic chemistry

Sodium persulfate is a specialized oxidizing agent in chemistry, classically in the Elbs persulfate oxidation and the Boyland–Sims oxidation reactions. It is also used in radical reactions; for example in a synthesis of diapocynin from apocynin where iron(II) sulfate is the radical initiator.^[5]

Safety

The salt is an oxidizer and forms combustable mixtures with organic materials such as paper.
