Embodiment 1

[0045] The hypochlorous acid disinfectant that present embodiment provides consists of:

[0046]

[0047] Wherein, the pH value of the acetic acid-sodium acetate buffer solution is 6, and the mass concentration of the sodium hypochlorite aqueous solution is 10%.

[0048] The compound of formula (1) described in this example was provided by Xi'an Ruixi Biotechnology Co., Ltd.

[0049] The preparation method that present embodiment provides described hypochlorous acid disinfectant is:

[0050] In a 100mL brown bottle, pour 10g of a mass concentration of 10% sodium hypochlorite aqueous solution, add dropwise glacial acetic acid while stirring, and adjust the pH of the solution to 6 (at this time, the amount of glacial acetic acid is 1.5g) and add 0.1g of formula (1) Shown water-soluble porphyrin, stir to dissolve, then add the acetic acid-sodium acetate buffer solution that pH value is 6 to dilute the solution to 100g, shake up and obtain hypochlorous acid disinfectant.

Abstract

In order to overcome the defects of poor stability, short shelf life and the like of a hypochlorous acid disinfectant in the prior art, the invention provides a stable hypochlorous acid disinfectant which comprises a mixture of the following components: a hypochlorite aqueous solution, a pH regulator, a stabilizer and a diluent, wherein the stabilizer is water-soluble porphyrin, porphyrin has a tetrapyrrole conjugated large pi rigid plane and a plurality of conjugated delocalized pi electrons, and can form ppi conjugation with Cl in hypochlorous acid, so that the hypochlorous acid structure ismore stable, the stability of the hypochlorous acid disinfectant is improved, the shelf life of the hypochlorous acid disinfectant is prolonged, the pH regulator is an acidic regulator, and the diluent is a buffer solution of conjugated acid-base pairs. The invention also provides a preparation method of the hypochlorous acid disinfectant and application of the hypochlorous acid disinfectant in the aspects of instrument disinfection, object surface disinfection, skin disinfection and air disinfection.

Description

technical field [0001] The invention relates to the technical field of disinfectants, in particular to a stable hypochlorous acid disinfectant and a preparation method thereof. Background technique [0002] Cl in the hypochlorous acid solution 2 , HClO, ClO - The dynamic balance, and many studies have shown that the bactericidal ability of hypochlorous acid and hypochlorite solution mainly comes from hypochlorous acid molecules. When the pH value is 4.0-6.5, the proportion of hypochlorous acid molecules in the aqueous solution is the highest, which is the state with the strongest bactericidal effect; when the pH value is lower than 3.0, chlorine gas will be produced, the stronger the acidity, the chlorine gas The larger the ratio, the chlorine gas will be released from the solution when it reaches a certain concentration; because chlorine gas is poisonous, it will cause harm to personal safety. Therefore, the production of hypochlorous acid solution should ensure that the...
