过氧乙酸(perovy acetic acid PAA)是一种无色液体,可溶于极性溶剂,微溶于芳香烃类,其分解产物为乙酸、氧气,完全燃烧可生成二氧化碳和水。PAA属强氧化剂,高浓度的PAA具有强腐蚀性、强刺激性,浓度大于45%或温度低至-20℃会产生爆炸,可致人体灼伤,是一种广谱、速效、高效灭菌剂,可用于空气消毒、环境消毒以及各种预防性消毒。
Perovy acetic acid (PAA) is a colorless liquid that is soluble in polar solvents and sparingly soluble in aromatic hydrocarbons. Its decomposition products are acetic acid and oxygen and are completely burned to produce carbon dioxide and water. PAA is a strong oxidant, high concentrations of PAA is highly corrosive, strong irritant, concentration greater than 45% or temperatures as low as -20 ℃ will produce an explosion, can cause human burns, is a broad-spectrum, rapid and efficient sterilizing agent , Can be used for air disinfection, environmental disinfection and a variety of preventive disinfection.
