preparation example Construction

[0021] see figure 1 , the present invention provides a kind of technical scheme: a kind of preparation method of hydrogen peroxide peracetic acid mixture, comprises the raw material of following weight part:

[0022] Hydrogen peroxide: 0-500 parts;

[0023] Acylating agent: 0-400 parts;

[0024] Acid catalyst: 0-10 parts;

[0025] Purified water: 0-900 parts;

[0026] Stabilizer: 0-20 parts.

[0027] The preparation steps are as follows:

[0028] Step 1: Measure 0 to 500 parts of hydrogen peroxide and place it in an enamel reaction tank;

[0029] Step 2: sequentially add 0-400 parts of acylating agent, 0-10 parts of acid catalyst, and 0-900 parts of purified water;

[0030] Step 3: stirring at 20-50°C for more than 4 hours;

[0031] Step 4: After the reaction is complete, add 0-20 parts of stabilizer.

[0032] It is characterized in that the acylating agent is acetic acid.

[0033] The acid catalyst is sulfuric acid.

[0034] The reaction temperature is between 20° C...

Embodiment 1

[0036] Prepare 100kg of high-efficiency disinfectant concentrate containing about 22% hydrogen peroxide and 4.5% peracetic acid:

[0037] Measure about 24kg of hydrogen peroxide, put it in an enamel reaction tank, add about 3.55kg of acetic acid, about 0.5kg of sulfuric acid, about 70.7kg of purified water, and stir at 20-50°C for more than 4 hours. After the reaction is complete, add About 0.15kg stabilizer.

[0038] The 1:20 dilution of the high-efficiency disinfectant concentrate can disinfect the surface of objects, and can also be diluted by an appropriate multiple for dry fog disinfection.

Embodiment 2

[0040] Prepare 100kg of high-efficiency disinfectant concentrate containing about 7% hydrogen peroxide and 1% peracetic acid:

[0041] Measure about 7.45kg of hydrogen peroxide, put it in an enamel reaction tank, add about 0.79kg of acetic acid, about 0.2kg of sulfuric acid, and about 91kg of purified water in sequence, and stir at 20-50°C for more than 4 hours. After the reaction is complete, add About 0.07kg stabilizer.

[0042] The high-efficiency disinfectant can be directly subjected to dry fog disinfection.

Abstract

The invention discloses a preparation method of a mixture of hydrogen peroxide and peracetic acid. The mixture comprises the following raw materials in parts by weight: 0 to 500 parts of hydrogen peroxide, 0 to 400 parts of an acylating agent, 0 to 10 parts of an acid catalyst, 0 to 900 parts of purified water, and 0 to 20 parts of a stabilizer. Hydrogen peroxide with unstable performance reacts with acetic acid, the generation amount of peracetic acid is controlled through the catalytic action of sulfuric acid and the stabilizing action of a stabilizer, the disinfectant containing the mixture of hydrogen peroxide and peracetic acid is prepared, and the disinfectant is high in disinfection efficiency, low in corrosivity, stable in performance and capable of being stored for a long time; and the usage amount of the disinfectant is adjusted, the concentration of the disinfectant after the reaction can be controlled, so that the disinfectant after the reaction can be directly used for disinfecting the surface of an object or directly used for dry fog disinfection.

Description

technical field [0001] The invention relates to the field of preparation of disinfectant, in particular to a method for preparing a mixture of hydrogen peroxide and peracetic acid. Background technique [0002] Generally speaking, disinfectants are divided into low-efficiency disinfectants, intermediate-efficiency disinfectants, and high-efficiency disinfectants. At present, the domestic market is generally dominated by medium-efficiency disinfectants such as ethanol. For the time being, there is no high-efficiency disinfectant with low residue, high disinfection efficacy and stable performance. Hydrogen peroxide is a strong oxidant, a single component can be used as a medium-effective disinfectant, but its performance is extremely unstable and easily decomposed, peracetic acid is also a strong oxidant, a single component can be used as a high-efficiency disinfectant, but there are also Extremely unstable situation, and high concentration peracetic acid is very corrosive an...
