Abstract

The invention relates to the technical field of hypochlorous acid production methods, in particular to a production method of high-stability hypochlorous acid. The production method of high-stabilityhypochlorous acid comprises the following steps: (1) mixing water with a hypochlorite solution to obtain a hypochlorite solution; (2) mixing the pypocholoride solution with an acidic substance, adjusting the pH value of the solution to 3-5, and filtering to remove insoluble substances; then adding an alkaline substance, adjusting the pH value of the solution to 5-6.5, and filtering to remove insoluble substances to obtain a hypochlorous acid solution; and (3) adding a stabilizer into the hypochlorous acid solution, and uniformly mixing to obtain the product. The method is high in efficiency and low in cost, the prepared hypochlorous acid solution has the advantages of being stable in concentration and convenient to use, the storage validity period reaches two years or longer, packaging, storage and transfer of the disinfection solution are achieved, commercialization of the disinfection solution becomes possible, the limitation that the disinfection solution is prepared and used on site in the prior art is overcome, and the method has industrial application value.

Description

technical field [0001] The invention relates to the technical field of hypochlorous acid production methods, in particular to a production method of high-stability hypochlorous acid. Background technique [0002] Hypochlorous acid (HClO) is a very active oxidizing agent with strong bactericidal effect. Hypochlorous acid is the core substance of the immune system of organisms. Dilute hypochlorous acid solution has a very efficient ability to kill microorganisms, and the use process is safe and pollution-free, so it is widely used in personal, family, medical, agricultural Disinfection, cleaning, nursing, etc. in various industries such as animal husbandry and breeding. However, due to the extremely high reactivity and instability of hypochlorous acid, its industrial production has not been realized. Since the middle of the last century, scientists have been trying to use various methods to achieve the industrial production of hypochlorous acid. [0003] So far, the researc...
