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 formulated according to the relationship of solubility with the principle of being easy to dissolve; on the other hand, it is carried out with the principle of not inventing obvious chemical reactions when preparing. Generally, iodide is dissolved in water, and a part is used to dissolve elemental iodine; another iodide aqueous solution is taken, iodic acid and / or iodate is dissolved in it, and then mixed with the above-mentioned iodine-dissolved iodine aqueous solution ; dissolving carboxylic acid and / or carboxylate, carboxylate in alcohol; finally mixing the solution containing carboxylic acid and / or carboxylate and carboxylate with the above-mentioned iodine, iodide, iodic acid and / or The iodate solution is mixed evenly, and the remaining water is added to the full amount.

[0067] For the above components, if the water content in the system is less and the alcohol content is lar...

Embodiment 1

[0080] Iodine-containing disinfectant with long-term component stability, its components and their 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 of 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 after fully stirring, add the remaining about 139g of water under stirring to obtain a uniform solution. When preparing, pay attention to adding the B1 solution slowly while fully stirring.

[0084] According to the detection method of the above-mentioned ...

Embodiment 2

[0086] Iodine-containing disinfectant with long-term component stability, its components and their 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 of raw material liquid as an example, the specific preparation method is as follows:

[0089] Dissolve 23.5g of iodine in a mixture of 139g of ethanol and 275g of ethyl acetate, and add 10.2g of hydrogen iodide (added in the form of 57% hydroiodic acid, the water in which is converted to 7.7g, a total of 17.9g of hydroiodic acid) , to obtain A2 solution; mix 162.6g of water with 380% acetic acid, then add 2.0g of iodic acid, and mix uniformly to obtain B2 solution; add B2 solution into A2 solution under full stirring, which is an iodine-containing disinfectant.

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

[0091] According...

Abstract

The invention discloses a stable iodine-containing disinfectant and a preparation method thereof, and the iodine-containing disinfectant comprises the following components by weight: 0.1-10% of elemental iodine or 1-40% of an iodine complex, 0.1-10% of iodide, 0.01-1.0% of an iodic acid compound, 0.1-40% of carboxylic acid and / or an acidic salt of carboxylic acid, 5-80% of alcohol, 0.1-30% of carboxylic ester, and 5-88% of water. The iodide is composed of iodine negative ions and hydrogen ions or metal cations or ammonium ions or quaternary ammonium ions. The iodine-containing disinfectant is simple in preparation method and stable in component content 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 body sterilization for more than 100 years, and many iodine-containing disinfectant formulations have been developed to meet different use occasions. Iodine disinfectant has low tissue toxicity and is widely used in clinical, sanitation, daily life, livestock and poultry breeding, aquaculture, public places and drinking water. Before iodophor was invented, tincture of iodine (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 being gradually irritated Replaced by smaller iodophor disinfectants; the stability of complexed iodine has been greatly improved compared with uncomplexed iodine preparations, but its long-term component stability is still gr...
