[0053] In the preparation method of iodine-containing disinfectant of the present invention, select inorganic acid such as sulfuric acid, phosphoric acid etc. as raw material and can obtain stable iodine-containing disinfectant equally according to the reaction described above, but considering the safety of biocompatibility and use etc., Choose organic acids, and further choose carboxylic acids; carboxylic acids are milder in nature and better in biocompatibility than inorganic acids, and iodine can exert a more excellent disinfection and sterilization effect in an acidic medium environment. Therefore carboxylic acid is one of the essential raw materials of the present invention.
[0054] In the description of the present invention, the carboxylic acid preferably has certain water solubility and / or alcohol and / or ester solubility, and is more preferably a carboxylic acid that can undergo esterification reaction under the catalysis of elemental iodine. Such carboxylic acids inc...
Embodiment 1
[0073] 1.1 The raw material components and their consumption amounts for preparing iodine-containing disinfectant are as follows:
[0074] Elemental iodine 2%, anhydrous citric acid 10%, absolute ethanol 88%.
[0075] 1.2 Taking 1000g raw material liquid as an example, the specific preparation method is as follows:
[0076] Take about 300g of absolute ethanol, add 20g of elemental iodine and stir to dissolve to obtain A1 solution; dissolve 100g of citric acid in 400g of absolute ethanol to obtain B1 solution; About 180g of the remaining absolute ethanol is added to the above mixed solution under stirring to obtain a uniform solution, which is the disinfectant raw material solution; the raw material solution is reacted at 70°C under stirring for 12 hours, and then left to cool to obtain a product with long-term component stability. iodine-containing disinfectant.
