过氧乙酸(Peraetic acid),又叫过醋酸。是一种优良消毒剂,杀菌谱广,杀菌能力特别强,使用浓度低,消毒时间短,消毒后不遗留残毒,低温下使用也有效。在杀灭各种微生物筛选中名列前茅。合成工艺简单,取材方便,基层可以自己配制,价格便宜,便于推广。缺点是稳定性差,有醋酸味,浓的对金属有腐蚀性。为了推广使用,掌握生产技术,选择最优保存条件。我们制造了少量过氧乙酸,对影响稳定性的三因素二水平,进行了观察,现报告如下:材料和方法一原料1 冰醋酸(分析纯),含量99%2 硫酸(分析纯),含量95—99%3 过氧化氢(分析纯),含量29%二配制方法取600毫升冰醋酸,加入1000毫升聚乙烯塑料瓶内,然后加入31.6毫升硫酸,轻摇使其混匀,再加入300毫升过氧化氢,轻摇均匀后静止于室温(18℃),72小时测其含量。此时浓度一般达高峰,加磷酸1.96毫升 Peracetic acid (Peraetic acid), also known as peracetic acid. Is a good disinfectant, broad spectrum bactericidal, bactericidal capacity is particularly strong, the use of low concentration, disinfection time is short, leaving no residue after disinfection, low temperature use is also effective. Ranked among the best in killing various microorganisms. Synthetic process is simple, easy to draw, the grass-roots can be their own preparation, the price is cheap, easy to promote. The disadvantage is the poor stability, acetic acid taste, concentrated on the metal corrosive. In order to promote the use of master production technology, choose the best storage conditions. We have produced a small amount of peracetic acid, the three factors affecting the stability of the second level were observed, are reported as follows: Materials and methods A raw material 1 acetic acid (analytical grade), 99% 2 sulfuric acid (analytical grade), content 95-99% 3 Hydrogen peroxide (analytical grade), content of 29% Two preparation method Take 600 ml of glacial acetic acid, add 1000 ml polyethylene plastic bottle, and then add 31.6 ml of sulfuric acid, shake it to mix, then add 300 Ml hydrogen peroxide, shake gently at room temperature (18 ℃), 72 hours to measure its content. At this point the concentration of the general peak, plus 1.96 ml of phosphoric acid
