Problems solved by technology

It can be seen from the results that adding substances such as potassium iodate is beneficial to stability, but its stability needs to be further improved
The instability of this iodine disinfectant in the system affects the disinfection performance and shelf life of the product, making the product unable to have the shortcoming of long-term stability, aggravating the pressure during production, stocking, storage and transportation, and causing fluctuations in the disinfection effect What affects the actual disinfecting effect is stability
[0003] When preparing an existing iodine-containing disinfectant, especially when the iodine-containing disinfectant uses iodide (such as potassium iodide) and / or iodate (such as potassium iodate) as a stabilizer, different addition sequences lead to a newly prepared iodine-containing disinfectant The difference in iodine element content in disinfectants leads to differences between different batches and affects industrial production

preparation example Construction

[0053] In the preparation method of iodine-containing disinfectant of the present invention, select inorganic acid such as sulfuric acid, phosphoric acid etc. as raw material and can obtain stable iodine-containing disinfectant equally according to the reaction described above, but considering the safety of biocompatibility and use etc., Choose organic acids, and further choose carboxylic acids; carboxylic acids are milder in nature and better in biocompatibility than inorganic acids, and iodine can exert a more excellent disinfection and sterilization effect in an acidic medium environment. Therefore carboxylic acid is one of the essential raw materials of the present invention.

[0054] In the description of the present invention, the carboxylic acid preferably has certain water solubility and / or alcohol and / or ester solubility, and is more preferably a carboxylic acid that can undergo esterification reaction under the catalysis of elemental iodine. Such carboxylic acids inc...

Abstract

The invention discloses a preparation method of an iodine-containing disinfectant with a stable component content, which comprises the following steps: mixing raw materials together and conducting reacting at 50-150 DEG C for 5-20 hours, wherein the raw materials comprise elemental iodine and any one of the following seven raw materials: (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, (6) carboxylic ester and water, and (7) carboxylic acid and water. According to the iodine-containing disinfectant, carboxylic acid, alcohol, water, ester and the like in the iodine-containing disinfectant are balanced through reversible esterification and / or ester exchange reaction under the condition that iodine serves as a catalyst, and / or simple substance iodine is subjected to disproportionation reaction under the condition that acid and water are contained to obtain stable balance among simple substance iodine, iodide ions and iodic acid. The iodine-containing disinfectant is stable in component and convenient to prepare, the content of iodine, iodide and carboxylic acid is kept stable after long-term storage (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 disinfectants are widely used in various aspects of industrial production and daily life, but the stability of iodine-containing disinfectants has always been a very challenging issue. The main reason for the instability of iodine-containing disinfectants is the reactive nature of simple iodine. In order to stabilize elemental iodine, iodides such as potassium iodide, sodium iodide, etc. are generally added; or acids are added, such as citric acid, salicylic acid, sulfuric acid, phosphoric acid, etc.; Adding iodide and iodate to the system can stabilize the iodine disinfectant to a certain extent, but its content still has obvious changes after long-term storage. For example, in "Influence of complexing agent PVP-K30 on povidone-iodine bactericidal effect and effect improvement" (T...
