Embodiment 1

[0035] Peracetic acid disinfectant consists of the following raw materials in percentage by weight: 2.5% hydrogen peroxide; 0.5% peracetic acid; 0.03% triethylenetetramine hexamethylene phosphoric acid; 0.01% water-soluble imidazoline amide; 0.02% of sodium toluenesulfonate; 0.01% of n-octanoic acid, the rest is water, and the weight percentage sum of each raw material is 100%.

[0036] The preparation method of the water-soluble imidazoline amide corrosion inhibitor described in Example 1 is: respectively weigh 17.2g of n-decanoic acid, 14.6g of triethylenetetramine, 1.0g of glacial acetic acid and 50g of toluene into the three-port tank equipped with a water separator. In the bottle, heat to 120°C, the water and toluene produced by the reaction are brought into the water separator in the form of azeotrope, and the condensation reaction is maintained for 1 hour; when no more water is produced in the water separator, the temperature is raised to 210°C, and the temperature is co...

Embodiment 2

[0038] Peracetic acid disinfectant consists of the following raw materials in percentage by weight: 5% hydrogen peroxide; 0.2% peracetic acid; 0.1% sodium tripolyphosphate; 0.005% water-soluble imidazoline amide; 0.08% sodium hexadecylsulfonate ; N-decanoic acid 0.005%, the rest is water, and the weight percentage sum of each raw material is 100%.

[0039] The preparation method of the water-soluble imidazoline amide corrosion inhibitor described in Example 2 is as follows: respectively weigh 20g of n-dodecanoic acid, 19.0g of tetraethylenepentamine, 1.0g of glacial acetic acid and 50g of toluene into the three-port tank equipped with a water separator In the bottle, heat to 130°C, the water and toluene produced by the reaction are brought into the water separator in the form of azeotrope, and the condensation reaction is maintained for 1.5h; when no more water is produced in the water separator, the temperature is raised to 220°C, Keep the temperature for 2 hours, carry out t...

Embodiment 3

[0041] Peracetic acid disinfectant consists of the following raw materials by weight percentage, hydrogen peroxide 17.5%; peracetic acid 5%; bis(1,6-hexylidene) triamine pentamethylene phosphoric acid 0.08%; water-soluble imidazoline amide 0.05%; sodium dodecylsulfonate 0.1%; lauric acid 0.05%, the rest is water, and the weight percentage sum of each raw material is 100%.

[0042] The preparation method of the water-soluble imidazoline amide corrosion inhibitor described in Example 3 is: respectively weigh 14.5g of n-octanoic acid, 24g of polyethylene polyamine, 1.5g of glacial acetic acid and 45g of toluene into a three-necked flask equipped with a water separator , heated to 126°C, the water and toluene produced by the reaction were brought into the water separator in the form of azeotrope, and the condensation reaction was maintained for 2 hours; when no more water was produced in the water separator, the temperature was raised to 230°C, and the temperature was kept constant...

Abstract

The invention provides a peroxyacetic acid disinfectant which comprises the following raw materials in percentage by weight: 0.1-20% of hydrogen peroxide and the balance of water. 0.1-5% of peroxyacetic acid; 0.001%-0.1% of a stabilizing agent; 0.001%-0.05% of a corrosion inhibitor; 0.001%-0.1% of a surface active agent; wherein the sum of the weight percentages of all the raw materials is 100%. The peroxyacetic acid disinfectant disclosed by the invention has the advantages of wide sterilization application range and quick sterilization; high stability is achieved, and stable storage can be achieved under the room temperature condition. The product is basically free of corrosion on metal such as molybdenum-chromium alloy, stainless steel, carbon steel, copper and the like and endoscope materials, so that the limitation caused by corrosivity of traditional peroxyacetic acid is greatly improved. The peroxyacetic acid disinfectant disclosed by the invention can be directly used without dilution, so that the use convenience of the peroxyacetic acid disinfectant is greatly improved, and the peroxyacetic acid disinfectant can be directly applied to multiple disinfection fields and scenes such as air disinfection, food hygiene and corrosion prevention, high-level disinfection of clinical samples and medical instruments (such as endoscopes and hemodialysis instruments) and the like.

Description

technical field [0001] The invention belongs to the technical field of chemical disinfectants, in particular to a peracetic acid disinfectant. Background technique [0002] Peracetic acid is a high-efficiency broad-spectrum chemical disinfectant, which has the advantages of low concentration, strong bactericidal effect, short disinfection time, and non-toxic decomposition products. It has been used in the field of disinfection at home and abroad for more than half a century. The prevention and control of nosocomial infection and the sanitation and anticorrosion of the food processing industry all play a very important role. During the SARS epidemic in 2003, it was used as the main force of disinfectant for sterilization and disinfection in hospitals and other public places. [0003] At present, the concentration of peracetic acid on the market is mostly 16-18wt%. However, due to the characteristics of peracetic acid itself being unstable and easy to decompose, with the prol...
