Synonyms: ammonium persulfate, ammonium peroxydisulfate
Chemical formula: (NH4)2S2O8
International name: AMMONIUM PERSULFATE
CAS No.: 7727-54-0
Grade: import, pure, GOST 20478-75
Appearance: white powder
Ammonium persulphate (ammonium persulfate) is colorless hygroscopic crystals. It is freely soluble in water, strong oxidant. Water solution enters into an acid reaction. When heating above 120°, it turns into ammonium pyrosulphate (NH4)2S2O7 releasing oxygen. Rather dry salt remains unchanged for an indefinite time without decomposition.
Production
Ammonium persulphate is produced by electrolysis of ammonium sulphate solution in sulfuric acid.
Application
Ammonium persulphate is used as follows:
- in enzyme histochemistry,
- in electron microscopy as methacrylate polymerization catalyst used for cut packing,
- as an initiating agent in polymerization,
- for bleaching and disinfecting,
- in analytical chemistry, etc.
