Problems solved by technology

[0007] Existing iodine-containing disinfectants containing organic acids generally contain elemental iodine, iodide, water, alcohol, and carboxylic acid. This formula has a good disinfection and sterilization effect; , the composition will change, mainly manifested as a decrease in the content of elemental iodine and / or a decrease in the content of carboxylic acid, which affects the overall stability of the formula and will also cause fluctuations in the disinfection and sterilization effect to a certain extent

Embodiment 1

[0077] Iodine-containing disinfectant with long-term component stability, its components and their weight content are as follows:

[0078] Citric acid 2.0%, elemental iodine 2.0%, potassium iodide 1.5%, ethanol 70.0%, diethyl citrate 8.0%, water 16.5%.

[0079] Taking 1000g of disinfectant as an example, the specific preparation method is as follows:

[0080] 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 20g of citric acid and 80g of diethyl citrate in 700g of ethanol to obtain B1 solution; Add it into the A1 solution under stirring, and after fully stirring, add the remaining about 140g of water under stirring to obtain a uniform solution.

Embodiment 2

[0082] Iodine-containing disinfectant with long-term component stability, its components and their weight content are as follows:

[0083] Citric acid 3.0%, elemental iodine 2.0%, sodium iodide 3.0%, ethanol 65%, monoethyl citrate 5.0%, diethyl citrate 5.0%, triethyl citrate 1.0%, water 16%.

[0084] Taking 1000g of disinfectant as an example, the specific preparation method is as follows:

[0085] Take a small amount of about 25g of water, add 30g of sodium iodide to dissolve, and then add 20g of elemental iodine to completely dissolve the iodine to obtain A2 solution; then add 30g of citric acid, 50g of monoethyl citrate, 50g of diethyl citrate, citric acid Dissolve 10 g of triethyl ester in 650 g of ethanol to obtain B2 solution; add B2 solution to A2 solution under stirring, and after fully stirring, add the remaining water 135 g under stirring to obtain a uniform solution.

Embodiment 3

[0087] Iodine-containing disinfectant with long-term component stability, its components and their weight content are as follows:

[0088] Acetic acid 7.5%, elemental iodine 3.0%, ammonium iodide 3.0%, ethanol 49%, ethyl acetate 18.5%, water 19%.

[0089] Taking 1000g of disinfectant as an example, the specific preparation method is as follows:

[0090] Take a small amount of about 40g of water, add 30g of ammonium iodide to dissolve, and then add 30g of elemental iodine to completely dissolve the iodine to obtain A3 solution; dissolve 75g of acetic acid and 185g of ethyl acetate in 490g of ethanol to obtain B3 solution; Add it into the A3 solution under stirring, and add about 150 g of the remaining water under stirring after fully stirring to obtain a uniform solution.

Abstract

The invention discloses an iodine-containing disinfectant with long-term component stability. The iodine-containing disinfectant comprises the following components in percentage by weight: 0.1-10% of elemental iodine, 0.1-10% of iodide, 0.1-20% of carboxylic acid, 2-30% of carboxylic ester, 40-80% of alcohol and 5-30% of water, wherein the iodide is composed of iodine anions and hydrogen ions, metal cations or ammonium ions or quaternary ammonium ions. The contents of various components in the iodine-containing disinfectant disclosed by the invention are not obviously changed even if the iodine-containing disinfectant is placed for a long time, a relatively long shelf life can be maintained, and the quality standard is met.

Description

technical field [0001] The invention belongs to the field of disinfectants, in particular to an iodine-containing disinfectant with long-term component stability. Background technique [0002] The recurring occurrence of food safety incidents, the spread of zoonotic diseases, the development of large-scale breeding, and the continuous strengthening of people's concept of "prevention is more important than cure" medication, there is an urgent need for green and safe disinfectants to improve the breeding environment and prevent diseases. It is necessary not only to effectively kill the virus, but also to have no stress effect on livestock, poultry and aquatic products. [0003] Elemental iodine has been discovered for more than two centuries, and iodine has been used for sterilization for a century, and many iodine-containing disinfectants have been developed. Iodine-containing disinfectants have a wide antibacterial spectrum, low tissue toxicity, and are widely used; the sco...
