preparation example Construction

[0037] The present invention also provides a preparation method of the above-mentioned green environment-friendly peracetic acid disinfectant, comprising the following steps: taking each raw material according to the proportion;

[0038] a. Dissolving and reacting glacial acetic acid and citric acid to obtain homogeneous phase A;

[0039] b, hydrogen peroxide and boric acid are dissolved and reacted to obtain homogeneous phase B;

[0040] c. Mix the homogeneous phase A obtained in step a with the homogeneous phase B obtained in step b. After reacting at normal temperature, add sodium citrate and urea, stir again, and then stand for reaction at normal temperature to obtain peracetic acid disinfectant .

[0041] In order to solve the technical problems of traditional synthesis of peracetic acid, the present invention adopts physical and chemical technology to select compound weak acid to replace concentrated sulfuric acid for catalysis, and explores the optimal catalytic synthe...

Embodiment 1

[0047] Add 50 mL of 99.0 wt% glacial acetic acid into a round bottom flask, add 1 g of citric acid catalyst, heat to 40-60 ° C, stir for 20-30 minutes, and react to form acetyl homogeneous phase A;

[0048] Add 50 mL of 30 wt% hydrogen peroxide into a round bottom flask, add 1 g of boric acid catalyst, heat to 40-60 ° C, stir for 20-30 minutes, and react to form acidic hydrogen peroxide homogeneous phase B;

[0049] Add the above-mentioned homogeneous phase B into homogeneous phase A, stir for 20-30 minutes, then react at room temperature for 2-4 hours; The amount is 0.1% of the total material quality), stirred for 20 to 30 minutes, then left to react at room temperature for 24 to 72 hours to obtain peracetic acid disinfectant; adopt the typical method "Disinfection Technical Specifications" experimental technical specifications to measure, its The mass concentration of peracetic acid is 5-12%.

Embodiment 2

[0051] Add 50 mL of 99.0 wt% glacial acetic acid into a round bottom flask, add 2 g of citric acid catalyst, heat to 40-60 ° C, stir for 20-30 minutes, and react to form acetyl homogeneous phase A;

[0052] Add 100 mL of 30 wt% hydrogen peroxide into a round bottom flask, add 2 g of boric acid catalyst, heat to 40-60 ° C, stir for 20-30 minutes, and react to form acidic hydrogen peroxide homogeneous phase B;

[0053] Add the above-mentioned homogeneous phase B into homogeneous phase A, stir for 20-30 minutes, then react at room temperature for 2-4 hours; The amount is 0.2% of the total material quality), stirred for 20 to 30 minutes, and then left to stand at room temperature for 24 to 72 hours to obtain peracetic acid disinfectant; adopt the typical method "Disinfection Technical Specifications" experimental technical specifications to measure, and its The mass concentration of peracetic acid is 5-10%.

Abstract

The invention discloses an environment-friendly peracetic acid disinfectant and a preparation method and application thereof, and belongs to the technical field of pharmaceutical chemicals. The invention provides a peracetic acid disinfectant. The peracetic acid disinfectant is prepared from glacial acetic acid, hydrogen peroxide, citric acid, boric acid, sodium citrate and urea. The volume ratioof glacial acetic acid to hydrogen peroxide is 1-2:1-3; the addition amount of the citric acid is 1-10% of the mass of the glacial acetic acid; the addition amount of the boric acid is 1-10% of the mass of the hydrogen peroxide; the addition amount of the sodium citrate is 0.1-0.3% of the total mass of the materials; and the addition amount of the urea is 0.1-0.2% of the total mass of the materials. The peracetic acid disinfectant disclosed by the invention is simple to synthesize and operate, free of environmental pollution and industrial three wastes, has the characteristics of high efficiency and broad spectrum, can quickly kill bacteria, viruses, fungi and spores, and is a green, environment-friendly, non-toxic, harmless and residue-free environment-friendly disinfectant.

Description

technical field [0001] The invention belongs to the technical field of medicine and chemical industry, and in particular relates to a green and environment-friendly peracetic acid disinfectant and its preparation method and application. Background technique [0002] In the face of the sudden outbreak of pneumonia caused by a new type of coronavirus, and it coincides with the traditional Chinese New Year holiday, most medical material manufacturers cannot schedule production normally, resulting in tight market supply. Especially for the new coronavirus whose main route is the transmission of respiratory droplets, air blockage is an effective way to disinfect, but due to the narrow application range and high price of high-efficiency air disinfectants, the amount of high-efficiency air disinfectants has increased sharply during the outbreak of the new crown pneumonia epidemic. The contradiction between supply and demand in the market is prominent. [0003] Peracetic acid, also ...
