What Is Sodium Peroxide?
Sodium peroxide, Na2O2, is a sodium-based peroxide with various hydrate states. It is known for its antibacterial, bleaching, and deodorizing properties, making it valuable in household and industrial applications. Its CAS number is 1313-60-6.
Uses of Sodium Peroxide
Utilized as a bleaching agent for fibers, bones, and laundry, sodium peroxide is also employed in air purification in submarines, production of organic peroxides, and as a safe, odorless detergent. It is typically sold in powder form for ease of use.
Properties of Sodium Peroxide
Anhydrate sodium peroxide is a pale-yellow crystal with a melting point of 460°C and a boiling point of 675°C. It reacts exothermically with water and ignites upon contact with flammables. The octahydrate form is colorless and crystalline.
Types of Sodium Peroxide
Available in various quantities for research and industrial use, it is hygroscopic and requires careful handling and storage.
Other Information on Sodium Peroxide
1. Synthesis of Sodium Peroxide
Produced by heating metallic sodium in dry air or by reacting hydrogen peroxide with sodium hydroxide solution.
2. Chemical Reaction of Sodium Peroxide
Reacts violently with water to produce sodium hydroxide and hydrogen peroxide, and absorbs CO2 to form sodium carbonate. It is a strong oxidizing agent that should be kept away from moisture and combustibles.
3. Regulatory Information on Sodium Peroxide
Classified under various safety regulations, handling of sodium peroxide must adhere to legal standards due to its hazardous nature.
