Problems solved by technology

[0005] As can be seen from the above analysis, each component in the above-mentioned iodine disinfectant containing elemental iodine, iodide, carboxylic acid, alcohol and water is actually a complex reaction system coupled and interrelated, and the change of a certain component will Directly or indirectly affect other components in the reaction system, eventually causing changes in the content of each component in the system
Moreover, the same component may have opposite effects on different reactions in iodine-containing disinfectants, so it is difficult to take into account the stability requirements of different reactions at the same time
For example, for water, when its content is more, it is beneficial to slow down the esterification reaction, thus is conducive to the content of stabilizing carboxylic acid, but when the water content is more, it is unfavorable to the reaction of iodine and water (that is, to accelerate the reaction ), resulting in a significant drop in iodine elemental content, without the use of iodine elemental content to stabilize
For alcohol, when its content is more, it is beneficial to the stability of iodine element content, but it will accelerate the esterification reaction, thereby affecting the stability of carboxylic acid content.
[0006] The instability of iodine-containing disinfectant components increases the pressure during production, stocking, storage, and transportation

preparation example Construction

[0063] The preparation method of the iodine-containing disinfectant of the present invention is directly prepared at normal temperature, does not need to use heating operation, does not need to use heating equipment, and is more convenient to operate, does not need complicated and accurately set feeding sequence and process, and different batches The component content of the disinfectant products among them is consistent, which is suitable for industrial scale production. The components of this iodine disinfectant are relatively stable, and can maintain the stability of elemental iodine and carboxylic acid content for a long period of time.

[0064] The iodine-containing disinfectant prepared by the method of the invention can be directly used for disinfection, or can be used after being diluted with water. According to the concentration of the original solution, if you can choose to dilute it by 50-1000 times, you can disinfect it by soaking, spraying, etc.

Abstract

The invention discloses an iodine-containing disinfectant containing sulfone and/or sulfoxide as well as a preparation method and application of the iodine-containing disinfectant, the iodine-containing disinfectant comprises the following components in percentage by weight: 20-98% of sulfone and/or sulfoxide, 0.1-20% of elemental iodine, 0.1-15% of iodide, 0.1-60% of carboxylic acid and 1-70% of water, and the sulfone and/or sulfoxide is water-soluble. The iodine-containing disinfectant is stable in iodine component content, especially stable in iodine simple substance and carboxylic acid content, simple in preparation method and capable of being used for environment and article disinfection.

Description

technical field [0001] The invention belongs to the field of iodine-containing disinfectants, and in particular relates to an iodine-containing disinfectant containing sulfone and / or sulfoxide, a preparation method and application thereof. Background technique [0002] Iodine disinfectants are widely used in various aspects in industrial production and daily life; in order to improve the disinfection performance of iodine-containing disinfectants, acidic substances are usually added thereto, such as the iodic acid mixed solution of sulfuric acid and phosphoric acid (containing complex iodine, Phosphoric acid, sulfuric acid, etc.); adding organic acids is also a common method, such as citric acid, salicylic acid, etc. Acidic conditions promote disinfection. Alcohol is a commonly used solvent in iodine disinfection, such as ethanol, glycerin, etc., which can greatly improve the stability of iodine. [0003] Although the existing common disinfectant components containing iodi...
