Problems solved by technology

[0003] (1) Hydrogen peroxide has poor storage stability;
[0004] (2) Electrolysis was often used to manufacture hydrogen peroxide in the past, so the price is more expensive;
[0005] (3) The sterilization speed of hydrogen peroxide is slow, and the applicable concentration is higher
In addition, people's requirements for environmental protection have been further improved. The fact that chlorinated disinfection water that has been used for many years is prone to secondary pollution, causing rectal cancer, bladder cancer and colon cancer, has aroused widespread concern from people all over the world, forcing artificial production to meet environmental protection requirements. Disinfectant

Embodiment 1

[0022] Example 1, take 1000 grams of 35% hydrogen peroxide, add 7 milliliters of the complex solution of silver nitrate and sodium hexametaphosphate, add 2 milliliters of 85% concentrated phosphoric acid under stirring, and adjust the pH value of the solution to 0.5-4, which is to improve Disinfectant with bactericidal activity of hydrogen peroxide.

[0023] Note: The preparation method of the complex solution of silver nitrate and sodium hexametaphosphate is as follows: first weigh 100 grams of silver nitrate and add 500 ml of water to dissolve it, then weigh 350 grams of sodium hexametaphosphate and add 1000 ml of water to dissolve it.

[0024] Take 5 milliliters of silver nitrate solution and add 2 milliliters of sodium hexametaphosphate solution, stir and mix evenly to obtain silver nitrate sodium hexametaphosphate complex, which is a transparent viscous liquid.

[0025] The disinfectant prepared by this method, when the active ingredient content is 0.02%, can kill Escheri...

Embodiment 2

[0026] Example 2, weigh 1000 grams of 30% hydrogen peroxide, add 2-10 grams of benzoic anhydride and glutaric anhydride and stir evenly, then add a certain amount of stabilizer and pH regulator and stir evenly, adjust the pH value of the solution to 0.5- 4. It is a disinfectant that improves the bactericidal activity of hydrogen peroxide. This disinfectant not only has strong bactericidal power, but also has a wide bactericidal spectrum. It is stored for one year under the condition of avoiding light, and the content of hydrogen peroxide, the active ingredient, decreases by less than 5%.

Embodiment 3

[0027] Embodiment 3, weighing 1000 grams of 45% hydrogen peroxide, 1000 grams of glacial acetic acid and stirring evenly, slowly adding 20 grams of sulfuric acid and stirring evenly, then adding a certain amount of stabilizer and stirring evenly, adjusting the pH value of the solution to 0.5-4, that is A disinfectant for enhancing the bactericidal activity of hydrogen peroxide. This disinfectant not only has strong bactericidal power, but also has a wide bactericidal spectrum.

[0028] The disinfectant prepared by this method has an active ingredient content of 50mg / l, which can kill Escherichia coli 100% in 1 minute: the concentration is 3500mg / l, which can kill Mycobacterium tuberculosis in 5 minutes; It can kill polio virus; the concentration is 5000mg / l, and it can kill Bacillus subtilis spores in 10 minutes.

[0029] The preparation process is as follows:

[0030] Dissolving→mixing→synthesis (adding activator, PH regulator, pH value is controlled at 0.5-4)→temperature c...

Abstract

A disinfectant able to increase the bactericiding activity of hydrogen peroxide is prepared from the aqueous solution of hydrogen peroxide, the activating agent chosen from the complex of metallic ion (Fe, Cu, Ag or Mg), the anhydride of acetic acid, propionic acid, butanedioic acid, etc and the stabilizer chosen from organic acid and inorganic acid through proportional mixing, and controlling pH=0.5-4 and temp to be lower than 100 deg.C. Its advantages are high bactericiding power, broad spectrum and high stability.

Description

technical field [0001] The utility model relates to a composition of various chemical substances, in particular to a disinfectant which uses hydrogen peroxide as a parent material and supplemented with other chemical substances to improve its bactericidal activity and a preparation process thereof. 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) Hydrogen peroxide has poor storage stability; [0004] (2) Electrolysis was often used to manufacture hydrogen peroxide in the past, so the price is more expensive; [0005] (3) The sterilization speed of hydrogen peroxide is slow, and the applicable concentration is relatively high. ...
