Peroxyacetic acid, пероксиуксусная acid, перуксусная acid, NUK 2915210000
Peracetic acid (peroxyacetic acid, peracetic acid, NAA) - chemical compound, organic peracid with the formula CH 3 SB 3 N.
It is a colorless liquid with a pungent odor.
Peracetic acid CH3C (O) UN is formed by the action of concentrated hydrogen peroxide on glacial acetic acid acid, the equilibrium constant is 0.37. Peracetic acid is produced by gradually adding acetic acid and hydrogen peroxide to water, containing sulfuric acid as a catalyst. The resulting mixture is kept for up to ten days to increase the yield. Acetyl chloride or acetic anhydride can also be used to obtain NAA.
Peracetic acid is also formed in nature as a result of photochemical reactions.
Synthesis of other compounds
Main uses of peracetic acid in industry - epoxy synthesis . In this process, an oxygen atom is transferred to a double bond, for example, ethylene or propylene form epoxies or alcohols. It can also be used in the production of glycerin from propylene. And it is used in the production of nylon.
Peracetic acid - strong and comfortable disinfectant due to high oxidative potential. It is effective against a wide range of microorganisms and is not inactivated by the enzymes catalase and peroxidase, which deactivate hydrogen peroxide. It can be used in a wide temperature range (0-40 ° C), and a wide pH value (3.0-7.5), for washing in hard water.
In the US, the EPA has registered peracetic acid as an antimicrobial agent in 1985 for residential use on hard surfaces. Applications include agricultural areas, food service areas, medical equipment and home bathrooms. Peracetic Acid is also registered for use in creameries and cheese factories and food processing equipment. Also as a pasteurizer in breweries and wineries. It is also used to disinfect medical supplies, to prevent biofilm in meat production, and as a water purifier and disinfectant.
