Peracetic acid is believed to function in a similar fashion as other oxidizing agents by reacting with cellular proteins and enzymes.
WebHowever, pH and temperature do influence peractetic acid activity. Peracetic acid is more effective when the pH value is 7 than at a pH range between 8 and 9. At a temperature of 15 °C and a pH value of 7, five times more peracetic acid is required to affectively deactivate pathogens than at a pH value of 7 and a temperature of 35 °C. WebPeroxyacetic acid is a combination of two important and versatile compounds: hydrogen peroxide and acetic acid. The two chemicals combine to form a new compound, peroxyacetic acid. This is an equilibrium reaction where over a period of hours, peroxyacetic acid is formed in situ by assuming elements of both reagents to form the new compound.
WebPeracetic acid (also peroxyacetic acid, PAA, CH 3 COOOH) can be obtained by mixing hydrogen peroxide with acetic acid (AcOH). Because of its strong oxidizing character, PAA is often used as bleach or disinfectant. The main field of application is the sterilization of plastic bottles in the bottled beverage production.
