Disinfectant based on sulfonated oleic acid peroxide and octylic acid peroxide and preparation method of disinfectant

Abstract

The invention discloses a disinfectant based on sulfonated oleic acid peroxide and octylic acid peroxide and a preparation method of the disinfectant. The disinfectant is prepared from the following raw materials in percentage by weight: 5.50-7.50% of glacial acetic acid, 0.95-4.00% of sulfonated oleic acid, 12.25-14.25% of hydrogen peroxide, 0.04-0.06% of sodium glucoheptonate, 0.10-0.20% of aluminum sulfate, 5.60-6.40% of sodium octane sulfonate, 0.36-0.40% of sodium xylene sulfonate, 4.00-6.00% of octylic acid, 17.05-18.10% of sulfuric acid and the balance of deionized water. The preparation method comprises the following steps: adding the deionized water, glacial acetic acid, aluminum sulfate, sodium xylene sulfonate and octylic acid into a reactor for stirring; reducing the temperature to 17-20 DEG C, and adding sulfuric acid for stirring; adding sulfonated oleic acid and sodium octane sulfonate for stirring; adding sodium glucoheptonate at the temperature of 30 DEG C for stirring; adding hydrogen peroxide; and curing under the closed condition at the temperature of 35-38 DEG C, thereby obtaining the product. The disinfectant disclosed by the invention is high in sterilization efficiency, high in stability, long in quality guarantee period and low in working concentration and is capable of monitoring the disinfection concentration online in real time.

Description

technical field [0001] The invention relates to the technical field of disinfectants, in particular to a high-efficiency and high-stable disinfectant based on online real-time monitoring of peroxysulfonated oleic acid and peroxyoctanoic acid and a preparation method thereof. Background technique [0002] Since the 1890s, peroxidized organic acid technology has been used in the disinfection of food industries such as beverages and brewing. Peracetic acid and peroxyoctanoic acid are known to be effective disinfectants and have been used alone and in combination (mixed peracids) in a variety of formulations. However, existing peroxygen organic acid disinfectants have low bactericidal efficiency, strong pungent smell, poor stability, overly cumbersome monitoring methods, short shelf life and other problems, and specifically have the following disadvantages: [0003] 1. The sterilization efficiency of peroxygen organic acid is not high: the disinfectant used on the surface of fo...

AI Technical Summary

Problems solved by technology

However, existing peroxygen organic acid disinfectants have low bactericidal efficiency, strong pungent smell, poor stability, overly cumbersome monitoring methods, short shelf life and other problems, and specifically have the following disadvantages:

[0003] 1. The sterilization efficiency of peroxygen organic acid is not high: the disinfectant used on the surface of food processing equipment in the market is generally a single peracetic acid disinfectant or a mixture of peracetic acid and peroxyoctanoic acid, and the effective concentration used is generally About 200ppm, for bacterial spores that are not easy to kill, generally the effective concentration needs to be increased to about 500-1000ppm before they can be completely killed. Costs (increased volume of finished disinfectants used, higher cost of transporting finished products), storage costs (hazardous chemicals need special storage, too much storage space will lead to higher storage costs) and use process all cause a lot of inconvenience

[0004] 2. The monitoring method is too cumbersome: the current method of measuring and measuring is titration or conductivity monitoring. Among them, titration is a manual process, which depends on the skills of the operator, and there are certain deviations in the results; in addition, although peracid disinfectants can Through the determination of the conductivity probe, but the conductivity is affected by the water quality, the accuracy of its measurement fluctuates over the years and cannot be standardized in the production facilities

So, neither conductivity nor titration is an ideal solution

[0005] 3. Short shelf life: As the concentration of peroxyorganic acid increases, its stability decreases. Under normal temperature conditions, the shelf life is generally half a year, and the longest is only 1 year.

[0006] 4. Poor stability in the use process: under the same effective concentration of peracetic acid prepared, the decrease rate of POAA per unit time of circulation in the filling machine is 1-2ppm / s, while the decrease rate of peroxyoctanoic acid is 3- 4ppm / s

[0007] 5. Strong pungent smell: Common peroxy organic acids are generally peracetic acid disinfectant alone or a disinfectant mixed with peracetic acid and peroxyoctanoic acid. There is a certain amount of hydrogen peroxide and acetic acid in the solution, and acetic acid has strong pungent odor

Due to the high concentration of disinfectant used to ensure the space or the equipment is in a sterile state, the processing process will cause irritation to the eyes and nose of the operator, which is not conducive to the health of the operator
