Binary disinfectant

Abstract

The invention discloses a binary disinfectant. The binary disinfectant comprises a liquid A and a liquid B, wherein the liquid A comprises acetic acid having the mass concentration of 95-98% and sulfuric acid having the mass concentration of 95-98%, while the liquid B is hydrogen peroxide having the mass concentration of 27.5-35%. The invention also discloses a preparation method of the binary disinfectant. The binary disinfectant is characterized in that glacial acetic acid and hydrogen peroxide taken as the major raw materials and prepared into the binary packaged disinfectant so that the sterilization effect and the stability of the disinfectant can be enhanced and then the disinfectant is capable of killing hepatitis A and B viruses, persistent viruses, influenza viruses and bacterial spores, and also capable of killing salmonella typhi, vibrio cholera, diarrhea and escherichia coli. The binary disinfectant can be used as the major disinfectant for controlling various viruses and the hospital cross infection, and can be applied to the disinfection and sterilization of viral pollutants, indoor and outdoor environments, hospital wards, common bathing pools, kindergartens, public places, breeding industry, hog houses, food processing industry, sewage treatment and the like.

Description

technical field [0001] The invention relates to a disinfectant, in particular to a binary disinfectant. Background technique [0002] Peracetic acid is an ancient disinfectant. Its preparation method is: mix the reserved glacial acetic acid and hydrogen peroxide according to the formula ratio, stir, then add a certain amount of sulfuric acid to stir again until uniform, and place it for 24 to 48 hours. For testing, when glacial acetic acid reacts with hydrogen peroxide to generate the highest concentration of peroxide, then add 8-hydroxyquinoline or urea to make the liquid turn yellow, take out the supernatant, and then dilute it in a certain amount before use. [0003] The product that above-mentioned this production method generates has the following defects: 1. poor stability: the shelf-life is only three months, and the concentration drop rate of peracetic acid after more than half a year is 50%, which is not suitable for long-term preservation. ② After the concentratio...

AI Technical Summary

Problems solved by technology

[0003] The product produced by the above-mentioned production method has the following defects: 1. poor stability: the shelf life is only three months, and the concentration of peracetic acid drops by 50% after more than half a year, which is not suitable for long-term preservation

② After the concentration is reduced, the bactericidal effect will naturally decrease

3. The cost of production is high. If 8-hydroxyquinoline or urea is not added in this production process, glacial acetic acid and hydrogen peroxide contain a large amount of metal ions, which can accelerate the reduction of product stability, which greatly increases the cost of the product and the relative profit. Significantly reduced, not convenient for production and sales

④According to the physical and chemical properties of peracetic acid, it is easy to decompose naturally during storage. In addition, when glacial acetic acid is mixed with hydrogen peroxide, more metal ions are produced, and it is easier to produce accelerated decomposition. If the acceleration is too strong, it is easy to produce redox reaction, and it is easy to produce explosive decomposition, which is more dangerous in storage and difficult to promote
