Physicochemical Property of Sodium persulfate powder

Sodium persulfate CAS 7775-27-1 Also known as sodium persulfate. White crystal or crystalline powder. Odorless. Odorless. Molecular formula Na2S2O8, relative molecular mass 238.13. Gradually decomposed at room temperature, can be rapidly decomposed by heating or in ethanol, after decomposition, release oxygen and generate sodium pyrosulfate.

Moisture and platinum black, silver, lead, iron, copper, magnesium, nickel, manganese and other metal ions or their alloys can promote the decomposition of high temperature (200 ℃ or so) rapid decomposition, the release of hydrogen peroxide.Sodium persulfate powder is soluble in water (20 ℃ when 70.4). It has strong oxidizing property. It has strong irritation to the skin, prolonged contact with the skin can cause allergies, attention should be paid to the operation.

Oral LD50895mg/kg in rats.Keep sealed. Laboratory by heating ammonium persulfate and caustic soda or sodium carbonate solution, remove ammonia and carbon dioxide and get Sodium persulfate Raw Materials .

Production methodprocess of Sodium persulfate powder

• (1)The aqueous solution of ammonium sulfate is oxidized by electrolysis to produce ammonium persulfate, and then compound decomposition reaction with sodium hydroxide is carried out, and the ammonia produced by by-products is expelled, and then concentrated, crystallized and dried under reduced pressure, and Sodium persulfate Raw Materials can be obtained. (NH4)2S2O8+2NaOH→Na2S2O8+2NH3+2H2O.
• 
• (2) Electrolysis of cold sulfuric acid can be produced peroxodisulfuric acid, and then with the action of alkali, can be produced Sodium persulfate powder. (I) 2HSO2 + 2HSO2 + 2HSO2 + 2HSO2 (I) 2HSO4 - 2e → H2S2O8 (II) H2S2O8 + 2NaOH → Na2S2O8 + 2H2O.
