Embodiment 1

[0117] 1.1 The raw material components and their consumption amounts for preparing iodine-containing disinfectant are as follows:

[0118] Elemental iodine 2%, potassium iodide 1.5%, anhydrous citric acid 20%, absolute ethanol 76.5%.

[0119] 1.2 Taking 1000g raw material liquid as an example, the specific preparation method is as follows:

[0120] Take about 300g of absolute ethanol, add 20g of elemental iodine and stir to dissolve, then add 15g of potassium iodide to dissolve to obtain A1 solution; dissolve 200g of citric acid in 400g of absolute ethanol to obtain B1 solution; add B1 solution to In the A1 solution, after fully stirring, add about 65g of the remaining anhydrous ethanol to the above mixed solution under stirring to obtain a uniform solution, which is the disinfectant raw material solution; react the raw material solution at 60°C for 18 hours under stirring, and then place it to cool , to obtain an iodine-containing disinfectant with long-term component stabil...

Abstract

The invention discloses an iodine-containing disinfectant with stable component content, which is characterized in that the iodine-containing disinfectant is prepared by reacting raw materials at 60-100 DEG C for 5-18 hours, raw materials for preparing the iodine-containing disinfectant comprise elemental iodine, iodide and any one of the following six components: (1) carboxylic acid and alcohol, (2) carboxylic acid, alcohol and water, (3) carboxylic acid, alcohol, carboxylic ester and water, (4) alcohol, carboxylic ester and water, (5) carboxylic acid, carboxylic ester and water, and (6) carboxylic ester and water, and the mass content of water in the iodine-containing disinfectant is not more than 30%. All the components of the iodine-containing disinfectant are balanced through a reversible esterification reaction under the condition that iodine is used as a catalyst. The iodine-containing disinfectant is stable in component stability, the contents of iodine, iodide and carboxylic acid of the iodine-containing disinfectant are kept stable after long-term storage (for at least two years), and the iodine-containing disinfectant has a stable disinfection and sterilization effect.

Description

technical field [0001] The invention belongs to the field of disinfectants, in particular to an iodine-containing disinfectant with stable component content. Background technique [0002] Iodine-containing disinfectants have been used for more than 100 years, and many formulations of iodine-containing disinfectants have been developed. It is used for disinfection of human skin, wound surface, mucous membrane surface, surgical instruments, pool water, drinking water, sanitation treatment of tableware and environmental disinfection. [0003] Especially with the cooperation of some acidic substances with disinfection and bactericidal effects, iodine can show more excellent disinfection and bactericidal effects. Alcohols are also commonly used ingredients for disinfection and sterilization, and they can strengthen coupling with iodine and acid. Therefore, many iodine-containing disinfectants also contain carboxylic acids and alcohols. In order to improve the solubility of ele...
