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.

摘要翻译： 制备其中对人体安全的氯酸易于处理和少量产生二氧化氯的亚氯酸水溶液的生产方法，用作食品加工中预处理的消毒剂。 向氯酸钠水溶液中加入硫酸或其水溶液，其用量和浓度使得水溶液的pH可以保持在2.3-3.4，从而使它们反应并产生氯酸。 随后，将过氧化氢以等于或大于还原反应所需量的量加入到氯酸中，从而产生亚氯酸。 将无机酸，无机酸盐，有机酸和有机酸盐中的任何一种，或其两种或多种，或其组合或这些加入到含有氯酸的水溶液中，由此可以长时间存在氯和酸 水溶液的pH值调节至3.2-7.0。 因此，赋予了高杀菌力。

摘要： Chlorous acid is generated from a chlorite salt precursor, a chlorate salt precursor, or a combination of both by ion exchange. The ion exchange material facilitates the generation of chlorous acid by simultaneously removing unwanted cations from solution and adding hydrogen ion to solution. Chlorine dioxide is generated in a controlled manner from chlorous acid by catalysis. Chlorine dioxide can be generated either subsequent to the generation of chlorous acid or simultaneously with the generation of chlorous acid. For catalysis of chlorous acid to chlorine dioxide, the chlorous acid may be generated by ion exchange or in a conventional manner. Ion exchange materials are also used to purify the chlorous acid and chlorine dioxide solutions, without causing degradation of said solutions, to exchange undesirable ions in the chlorous acid and chlorine dioxide solutions with desirable ions, such as stabilizing ions, and to adjust the pH of chlorous acid and Chlorine dioxide solutions.

摘要： The invention is a method of producing stable chlorous acid for use as a cleaning agent and biocidal composition. The method passes a salt of an oxy-chloro acid over a resin to allow for an ion exchange that produced the oxy-chloro acid. The invention allows for the production of a stable chlorous acid that can be used as a biocidal agent and a cleaning agent without the effect on many surfaces or membranes as normal oxy-chloro compositions.

摘要： Process for the preparation of chlorite salts by the controlled reaction of chlorine dioxide with a reducing agent under reduced pressure to form chlorous acid. The chlorous acid is reacted with an aqueous solution of base to form the desired chlorite salt. The process is rapid, economical and is conducted in a generator which is significantly smaller than equipment currently used for production of chlorite salts.
