    • PROBLEM TO BE SOLVED: To provide a process for producing an aqueous solution containing chlorous acid wherein chlorous acid, which is safe for the human body, is easy to handle, and hardly generates chlorine dioxide, is yielded to be used as a disinfectant for pretreatment in food processing.SOLUTION: In the process for producing an aqueous solution containing chlorous acid, chlorous acid, which is safe for the human body, is easy to handle, and hardly generates chlorine dioxide, is generated to be used as a bactericide for pretreatment in food processing. To an aqueous sodium chlorate solution, sulfuric acid or an aqueous solution thereof in such an amount and concentration that the pH of the aqueous solution can be kept at 2.3-3.4 is added to react and generate chloric acid. Subsequently, when hydrogen peroxide is added to the chloric acid in an amount which is equal to or larger than the amount necessary for a reduction reaction, the chlorous acid is generated.
    • 待解决的问题:提供一种生产含有亚氯酸的水溶液的方法,其中对人体安全的氯酸易于处理并且几乎不产生二氧化氯被产生用作 消毒剂用于食品加工中的预处理。 解决方案:在生产含有氯酸的水溶液的方法中,对人体安全的氯酸易于处理,几乎不产生二氧化氯,被用作预处理的杀菌剂 食品加工。 加入氯酸钠水溶液,硫酸或其水溶液,使其水溶液的pH值保持在2.3-3.4,使其反应并产生氯酸。 随后,当将氯化氢加入到等于或大于还原反应所需量的量的氯酸时,产生氯酸。 版权所有(C)2013,JPO&INPIT
