Problems solved by technology

[0005] Complex iodine (also known as iodine complex), generally refers to a compound with no specific composition composed of a complexing agent and iodine molecules, generally has a high stability, compared to containing uncomplexed elemental For iodine-containing disinfectants, the stability of complex iodine-containing disinfectants has been greatly improved, but there is still a small amount of free elemental iodine, which is an important factor affecting the stability of complex-iodine-containing disinfectants;
[0006] General acid-containing iodine-containing disinfectants contain iodide, water, acid, and alcohol in addition to elemental iodine or iodine complexes; when this product is stored for a long time, the composition changes, mainly as The decrease of elemental iodine content and the change of acid content affect the overall stability of the formula and also cause fluctuations in the killing effect to a certain extent

preparation example Construction

[0066] The preparation method of the iodine-containing disinfectant of the present invention is prepared on the principle of easy dissolving according to the relationship of solubility; on the other hand, it is prepared on the principle of no obvious chemical reaction during preparation. Generally, iodide is dissolved in water, and a part is used to dissolve elemental iodine; the remaining iodide aqueous solution is taken, iodic acid and / or iodate salt are dissolved in it, and then it is mixed with the above-mentioned iodine-dissolved iodide aqueous solution ; Dissolving carboxylic acid and / or carboxylate, carboxylate in alcohol; finally mixing the solution containing carboxylic acid and / or carboxylate and carboxylate with above-mentioned iodine, iodide, iodic acid and / or Mix the iodate solution evenly, and add the remaining water to the full amount.

[0067] For the above components, if the water content in the system is small and the alcohol content is large, under the same ...

Embodiment 1

[0080] The iodine-containing disinfectant with long-term component stability, its component and its weight content are as follows:

[0081] Elemental iodine 2.0%, potassium iodide 1.5%, iodic acid 0.1%, citric acid 2.0%, ethanol 70.0%, diethyl citrate 8.0%, water 16.4%.

[0082] Taking 1000g disinfectant as an example, the specific preparation method is as follows:

[0083] Take a small amount of about 25g of water, add 15g of potassium iodide to dissolve, and then add 20g of elemental iodine to completely dissolve the iodine to obtain A1 solution; dissolve 1g of iodic acid, 20g of citric acid, and 80g of diethyl citrate in 700g of ethanol to obtain B1 solution ; Add the B1 solution to the A1 solution under stirring, and then add the remaining amount of about 139 g of water under stirring to obtain a uniform solution. When preparing, it should be noted that the B1 solution should be added slowly with full stirring.

[0084] The content of elemental iodine and acid in the abo...

Embodiment 2

[0086] The iodine-containing disinfectant with long-term component stability, its component and its weight content are as follows:

[0087] Elemental iodine 2.35%, hydrogen iodide 1.02%, iodic acid 0.20g%, acetic acid 38.0%, ethanol 13.9%, ethyl acetate 27.5%, water 17.03%.

[0088] Taking 1000g raw material liquid as an example, the specific preparation method is as follows:

[0089] Dissolve 23.5g of iodine in the mixed solution of 139g of ethanol and 275g of ethyl acetate, add 10.2g of hydrogen iodide (in the form of 57% hydriodic acid, and the water therein is converted to 7.7g, totaling 17.9g of hydriodic acid) , get A2 solution; mix 162.6g water with 380 acetic acid, then add iodic acid 2.0g, mix well to get B2 solution; add B2 solution to A2 solution under full stirring, that is, iodine-containing disinfectant.

[0090] The addition rate should be slow, and the B2 solution cannot be quickly added to the A2 solution.

[0091] The content of elemental iodine and acid in...

Abstract

The invention discloses a stable iodine-containing disinfectant and a preparation method thereof. The iodine-containing disinfectant comprises the following components by weight: 0.1-10% of elemental iodine or 1-40% of iodine complex, and 0.1-40% of iodide 10%, iodate compound 0.01-1.0%, carboxylic acid and / or acid salt of carboxylic acid 0.1-40%, alcohol 5-80%, carboxylate 0.1-30%, water 5-88%, the iodine Compounds are composed of iodide anions and hydrogen ions or metal cations or ammonium ions or quaternary ammonium ions. The preparation method of the iodine-containing disinfectant is simple, and the component content is stable after long-term storage.

Description

technical field [0001] The invention belongs to the field of disinfectants, in particular to a stable iodine-containing disinfectant. Background technique [0002] Iodine has been used for sterilization and disinfection of the body for more than 100 years, and many iodine-containing disinfectant formulations have been developed to meet different application occasions. Iodine disinfectant has low tissue toxicity and is widely used in clinic, hygiene, daily life, livestock and poultry breeding, aquaculture, public places and drinking water. Before iodophor was invented, iodine tincture (ethanol-containing iodine disinfectant, or iodine) was widely used in disinfection occasions, but because of the irritation of alcohol and the need for further deiodination after use, it is now gradually irritated. Replaced by smaller iodine-based disinfectants; compared with uncomplexed iodine preparations, the stability of complexed iodine has been greatly improved, but its long-term compone...
