What is peracetic acid? What is peracetic acid used for?

[Alias]Peracetic acid, peracetic acid, peracetic acid

[Molecular Formula]C2H4O3

[Structural Formula]CH3COOOH

peracetic acid

[Properties]Colorless transparent liquid with a strong pungent acetic acid odor. It is weakly acidic and easily volatile. It is a strong oxidizing agent. Relative density 1.2665 (20℃), boiling point 105℃, melting point 0.1℃, refractive index 1.3924 (20℃), flash point 40.5℃ (40% peracetic acid solution). Soluble in water, sulfuric acid and solvents such as ethanol and ether. It is unstable in nature. If the temperature is slightly higher, it will decompose and release oxygen to generate acetic acid. It explodes violently when heated to 110°C. It is usually stored as a 30% aqueous solution. Corrosive to skin. This product is a strong oxidant that can epoxidize olefins and oxidize aldehydes to carboxylic acids.

It is used medically as a broad-spectrum and highly efficient chemical sterilant, as well as insecticides, drinking water and food disinfectants.

[Brief preparation method]

① It is produced by reacting hydrogen peroxide with acetic acid in the presence of sulfuric acid catalyst.

② It is produced by the reaction of acetaldehyde and oxygen in the presence of cobalt acetate.

[Safety and Protection]Peracetic acid is a secondary organic oxidant, flammable and explosive, hazardous regulation number: 24001, made of plastic Packed in barrels, net weight per barrel is 5kg or 20kg. Store away from light and sealed. Avoid co-storage and transportation with organic matter.

Peracetic acid is highly toxic and highly irritating to the skin. If the skin comes into contact, rinse immediately with plenty of water.
