Problems solved by technology

[0003] (1) Poor storage stability after hydrogen peroxide dilution;
[0004] (2) Electrolysis was often used to manufacture hydrogen peroxide in the past, so the price is more expensive;
[0005] (3) The sterilizing speed of hydrogen peroxide is slow, and the use concentration is higher (the use metering is larger)
In addition, people's requirements for environmental protection have been further improved. The chlorinated drinking water that has been used for many years is prone to produce harmful substances such as trihalides, which can easily cause risks such as rectal cancer, bladder cancer, and colon cancer. People develop disinfectants that meet environmental health requirements

example 1

[0037] Example 1, take by weight the following components of raw materials: A component main raw material: 840 parts of hydrogen peroxide (content 59%) for subsequent use; B component activator: 70 parts of acetic anhydride (content 98%); Component stabilization regulator: 20 parts of phosphoric acid (content 85%), 20 parts of acetic acid and 10 parts of salicylic acid (content 98%) for later use; auxiliary materials for component D: 30 parts of ethanol and 10 parts of polyvinyl alcohol are mixed and dissolved for later use.

[0038] Put the hydrogen peroxide of component A in the container, add the mixed and dissolved component B and D component acetic anhydride, ethanol, polyvinyl alcohol solution under stirring, add the mixed and dissolved component C solution after stirring evenly, continue Stir for 30 to 60 minutes, stir evenly and then stand still for 2 hours to prepare a disinfectant that improves the bactericidal activity of hydrogen peroxide.

example 2

[0039] Example 2, take by weight the following components of raw materials: A component main raw material: 850 parts of hydrogen peroxide (content is 58%) for subsequent use; B component activator: 60 parts of glutaric anhydride (content 98%) Standby; component C stabilizer: 20 parts of glutaric acid, 40 parts of benzoic acid; auxiliary material of component D: 30 parts of ethanol for standby.

[0040] Put the hydrogen peroxide of component A in the container, add the mixed and dissolved components B, C and D glutaric anhydride, glutaric acid, benzoic acid, and ethanol solution under stirring, stir well and let stand Within 2 hours, a disinfectant that improves the bactericidal activity of hydrogen peroxide can be prepared.

example 3

[0041] Example 3, take by weight the following components of raw materials: A component main raw material: 860 parts of hydrogen peroxide (content is 57%) for subsequent use; B component activator: propionic anhydride (content of 98%) 50 parts for subsequent use ; Component C stabilizer: 15 parts of propionic acid and 50 parts of phthalic acid are mixed and dissolved for later use; component D auxiliary material: 25 parts of ethanol for later use.

[0042] Put the hydrogen peroxide of component A in the container, add the mixed and dissolved component B propionic anhydride and D component ethanol solution under stirring, and stir for 30 minutes; then add the mixed and dissolved component C propionic acid and phthalate Formic acid solution, continue to stir for 30 to 60 minutes, stir evenly and let it stand for 2 hours to prepare a disinfectant that improves the bactericidal activity of hydrogen peroxide.

Abstract

A disinfectant with hydrogen peroxide bactericidal activity is composed of A, B, C and D component. If the solute is metered by 100%, its weight account proportion of mixed solution A:B:C:D=5-100:1-50:1-100:1-1000 obtained through hydrogen cation resin exchanged and filtered, wherein A is hydrogen peroxide; B is form one or more of glutaric anhydride, adipic anhydride, succinic anhydride, acetic anhydride, propionic anhydride, benzoic anhydride and phthalic anhydride; C is from one or more of sulfuric acid, phosphoric acid, salicylic acid, tartaric acid, citric acid, dipicolinic acid, sorbic acid, acetic acid, glutaric acid, oxalic acid, succinic acid, acetic acid, propionic acid, benzoic acid, and phthalic acid; D is from one or more of ethanol, ethylene glycol, isopropanol, glycerol, and polyvinyl alcohol. It is a good stability, strong bactericidal, fungicidal spectrum-efficient disinfectant.

Description

technical field [0001] The invention relates to a compound disinfectant, especially a disinfectant with hydrogen peroxide as an active component. Background technique [0002] As early as the 19th century, some people in Europe used hydrogen peroxide as a disinfectant for clinical use. Later, some people used it for the disinfection of grain seeds and the disinfectant for poultry egg storage, hatching and reproduction. However, hydrogen peroxide is not widely used for disinfection and sterilization. , for the following reasons: [0003] (1) Poor storage stability after hydrogen peroxide dilution; [0004] (2) Electrolysis was often used to manufacture hydrogen peroxide in the past, so the price is more expensive; [0005] (3) The sterilizing speed of hydrogen peroxide is slow, and the use concentration is higher (the use metering is larger). [0006] With the development of science and technology, after the Second World War, the process of producing hydrogen peroxide by a...
