Sodium carbonate peroxyhydrate

Sodium Carbonate Peroxyhydrate. Sodium carbonate peroxyhydrate [15630-89-4], which contains about 14 wt % of active oxygen, has the composition 2Na C(% 3H202. A white, free-flowing solid, it generally can be used in all applications where perborate is used. Despite the fact that sodium carbonate peroxyhydrate has a greater rate of dissolution than sodium perborate tetrahydrate, the latter is usually favored for its good storage stability and better compatibility with the various materials used in formulations (79).

When 200 L of cyanide were spilled into the River Wey in Surrey, England in May 1999, peroxide was added to the river to save the fish. The peroxide breaks down into water and oxygen and raises the pH of the polluted water, causing the cyanide to break down more rapidly. The fish were saved by the additional oxygen added. The Environment Agency s Thames Region now includes peroxide crystals, or sodium carbonate peroxyhydrate, in their response kits for cyanide spills (OSHS, 1999). 

Molecular Addition. Oxyacid salts, metal peroxides, nitrogen compounds, and others from crystalline peroxyhydrates in the presence of hydrogen peroxide. When dissolved in water, the peroxyhydrates react as solutions of their components. The peroxyhydrates formed from sodium carbonate and urea are commercially available. Examples of peroxyhydrates can be found in the Hterature (29,30).
