Characteristic
Sodium persulfate is the inorganic compound with the formula Na2S2O8. It is the sodium salt of peroxydisulfuric acid, H2S2O8, an oxidizing agent. It is a white solid that dissolves in water. It is almost non-hygroscopic and has good shelf-life.
Chemical formula:Na2S2O8
Molar mass: 238.10 g/mol
Appearance: white powder
Density: 2.59 g/cm3;(Loose bulk density: 1.12 g/cm3)
Melting point: 180 °C (356 °F; 453 K) decomposes
Solubility in water:55.6 g/100 ml (20 °C)
Application
Sodium peroxydisulfate is used as a radical initiator for emulsion polymerization reactions like acrylonitrile butadiene styrene, detergent component, soil conditioner and soil remediation. It is also used for curing of formaldehyde adhesives. It acts as a bleaching agent and in the production of dyestuffs. It finds application in zinc and printed circuit boards and considered to be a replacement for ammonium persulfate in etching mixtures. Further, it is used in the preparation of diapocynin from apocynin. It plays a role in the conversion of phenols to para-diphenols in alkaline solution and of arylamines to aminophenols. It is actively involved in the Elbs persulfate oxidation and the Boyland-Sims oxidation reactions as an oxidizing agent.
