Sodium Peroxide With Cas 1313-60-6

Sodium Peroxide With Cas 1313-60-6

 

Sodium peroxide is one of the products of combustion in oxygen or air, single product sodium peroxide is white, but usually see the sodium peroxide with pale yellow, reason is that in the process of the reaction generates a small amount of ultra sodium oxide (NaO2, pale yellow). Sodium peroxide is easy to moisture, corrosive, should be sealed preservation. Sodium peroxide has strong oxidation and can be used to bleach textile products, wheat stalks, fiber, etc.

Use

Can be used as oxygen supply, strong oxidizer, with bleaching properties.

It can interact with CO2 and release O2.

2 na2o2 na2co3 co2 + 2 = 2 + O2

According to this property, it can be used in mines, tunnels, scuba diving, spaceships and other places without oxygen to convert the CO2 people exhale into O2 for breathing.

2. Sodium peroxide can be used to remove impurities of H2O and CO2 in O2.

3. Sodium peroxide can also be used for disinfection, sterilization and bleaching. It is commonly used as bleach, fungicide, disinfectant, deodorizer and oxidant in industry.

4. Molten sodium peroxide is a very good oxidant, oxidizing Fe to ferric acid, and even converting organic matter to carbonate at room temperature.

It can be used to make hydrogen peroxide. The process is as follows.

The aqueous solution of sodium peroxide is neutralized by phosphoric acid or sodium dihydrogen phosphate to PH: 9.0 ~ 9.7, so as to form the aqueous solution of sodium hydrogen phosphate and hydrogen peroxide.

(2) make said aqueous solution of hydrogen peroxide and sodium hydrogen phosphate cooled to + 5 ~ 5 ℃, which absolutely most of sodium hydrogen phosphate precipitate in ten water sodium hydrogen phosphate hydrate form.

(3) in the centrifugal separator of aqueous solution containing sodium hydrogen phosphate hydrate and hydrogen peroxide mixture separation, to make hydrogen phosphate sodium hydrate crystallization from hydrogen peroxide solution containing a small amount of sodium hydrogen phosphate.

(4) said to contain a small amount of sodium hydrogen phosphate aqueous solution of hydrogen peroxide in the evaporator evaporation, get with hydrogen peroxide and water vapor, and sodium hydrogen phosphate salt containing hydrogen peroxide solution from the bottom of the flow and return neutralizing tank.

The said steam containing hydrogen peroxide and water is decompressed and fractionated in the fractionating column to obtain about 30% hydrogen peroxide.

Its aqueous solution can be used as bleach agent (decolorizer), oxidizer, preservative, fungicide, deodorant, microanalysis.

Sodium peroxide is used as a bleaching agent in the textile and paper industries and as an analytical and chemical treatment for mining.
