增加过氧乙酸稳定性的主要措施之一是添加稳定剂。笔者选用国内4种常用配方,以草酸作为稳定剂进行了观察。配方1原料配比,双氧水:冰醋酸=8:10; 配方2为双氧水:醋酐=1:1; 配方3为双氧水:冰醋酸:浓硫酸=70:140:7.1: 配方4为双氧水:冰醋酸:浓硫酸=80
One of the major measures to increase peracetic acid stability is the addition of stabilizers. The author selects four kinds of domestic commonly used formula, oxalic acid as a stabilizer was observed. Recipe 1 is hydrogen peroxide: glacial acetic acid: concentrated sulfuric acid = 70: 140: 7.1: formula 4 is hydrogen peroxide: ice Acetic acid: concentrated sulfuric acid = 80
