Ammonium peroxodisulphate, ammonium persulphate

Ammonium peroxodisulphate (ammonium persulphate, ammonium persulphate) — ammonium salt of peroxodisulphuric acid, colourless monoklinny crystals, well water soluble.

The peroxodisulphate of ammonium is applied as the initiator of radical polymerization at suspension polymerization in aqueous medium (production of polyvinylchloride, polyvinyl acetate, polyacrylonitrile):

Also ammonium persulphate is used as the initiator of radical polymerization at preparation of poliakrilamidny gels for electrophoresis of proteins and nucleic acids.

Also it is applied as bleaching and desinfectant as oxidizer in the photo (weakening of dense photographic negatives), analytical chemistry, when etching printed circuit boards.

Food additive of E923.
