摘要： A process for producing aqueous chlorous acid solution in which chlorous acid, which is safe for the human body, is easy to handle, and less generates chlorine dioxide, is yielded and used as a disinfectant for a pretreatment in food processing. To an aqueous sodium chlorate solution is added 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 to thereby react them and generate chloric acid. Subsequently, 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 to thereby yield chlorous acid. Any one of inorganic acids, inorganic acid salts, organic acids, and organic acid salts, or two or more thereof, or a combination or these is added to the aqueous solution containing chlorous acid yielded, whereby the chlorous and acid can be present for long and the pH of the aqueous solution is regulated to regulated to 3.2-7.0. Thus, high bactericidal power is imparted thereto.

摘要： The present invention addresses the problem of providing a novel technique for producing aqueous chlorous acid. The present invention provides a method for producing chlorous acid, which comprises a step of adding chlorine dioxide (ClO2) to one or more components independently selected from an inorganic acid, an inorganic acid salt, an organic acid and an organic acid salt or a combination of two or more of the aforementioned components. In the method, chlorine dioxide (ClO2) is provided in the form of a gas. The method also comprises, subsequent to the above-mentioned addition step, a step of further adding one or more components independently selected from an inorganic acid, an inorganic acid salt, an organic acid and an organic acid salt or a combination of two or more of the aforementioned components.
