Problems solved by technology

[0002] In emergency rescue missions, more and more high-tech equipment and sensitive electronic equipment are used; however, since precision components and sensitive equipment are greatly affected by temperature and humidity, and have weak corrosion resistance, they cannot be used once they are polluted by nuclear, chemical, biological Therefore, research on low-corrosion and insulating decontamination technology for sensitive equipment is a research hotspot in the field of decontamination at home and abroad
[0003] Existing decontaminants such as "three-in-two" water-based disinfectant and "191" disinfectant are highly corrosive and can seriously damage equipment coatings and plastics, so they cannot be used for sensitive equipment. decontamination

Embodiment 1

[0035]Mix 50% ethanolamine, 8% benzyl alcohol, 27% dimethyl sulfoxide and 12.5% ​​18-crown-6 to obtain a clear solution, add 2.5% potassium hydroxide to the clear solution and stir until completely dissolved , to obtain the compound universal disinfectant. The acid function value of the compound universal disinfectant was determined to be 15.03, which is strongly alkaline.

Embodiment 2

[0037] Dynamic Disinfection Experiment of Chemical Warfare Agent Mustard Gas (Dichlorodiethylsulfide, HD)

[0038] Fix the reaction bottle on the vortex oscillator, place it in a constant temperature reaction box at 25°C, inject 200μ mustard gas into the reaction bottle with a micro-injector, and then quickly pipette 4mL of the compound universal disinfectant solution prepared in Example 1 and put it in Put it into the reaction bottle, start shaking at 800r / min and record the time. At regular intervals, use a pipette to sample 100 μL, put it into a 25 mL stoppered test tube with 100 μL of 10% HCl aqueous solution and 2 mL of petroleum ether extractant (inject into the lower layer of HCl aqueous solution to terminate the disinfection reaction), and quickly cap and seal , shake the test tube to make the solution in the tube fully mixed, then ultrasonically extract for 2 minutes, take the organic liquid after centrifugation, and measure the mustard gas residual rate according to ...

Embodiment 3

[0040] Disinfection experiment of staphylococcus aureus and subtilis var. niger spores

[0041] Pipette a certain amount of bacterial liquid with a pipette gun, add it to the reaction bottle containing 1ml of the compound universal disinfectant prepared in Example 1, put it in a water bath at 25°C for reaction and time it, and take 0.5mL after the specified time. Add 4.5mL neutralizer (including specified hydrochloric acid) to the reaction solution to terminate the disinfection reaction; place it on a vortex shaker for 5 minutes and mix evenly, apply 0.1ml of the sampling solution evenly on the surface of the nutrient agar plate, place it in an incubator at 37°C for 48 hours, and count the activity. Bacteria, as the disinfection group, the test was repeated 3 times. In the same way, unsterilized sample solution was diluted with PBS to a suitable dilution by 10 times and cultured as a positive control group.

[0042] Under the test temperature of 25°C±1°C, 3 repeated tests pro...

Abstract

The invention relates to a compounded universal type disinfectant. The compounded universal type disinfectant comprises a mixed solvent, caustic alkali and a complexing agent, wherein the mixed solvent comprises alkyl alcohol amine, alcohol and a polar nonprotic solvent, and the caustic alkali and the complexing agent are dissolved into the mixed solvent. The disinfectant provided by the inventionis one 'superbase' system, has extremely strong nucleophilicity, has extremely high reactivity on disinfection of military highly toxic chemicals and has relatively high solubility on insoluble gluemilitary highly toxic chemicals, so that disinfection efficiency of the disinfectant is enhanced; meanwhile, the disinfectant has extremely low conductivity, good storage stability, low corrosivenessand high safety and can be applied to disinfection of electronic sensitive equipment; besides, the disinfectant provided by the invention also has certain broad-spectrum property on microorganism disinfection, not only can be applied to the field of chemical defense and also can be applied to the fields of public health precaution and the like.

Description

technical field [0001] The invention relates to the field of disinfectants, in particular to a compounded universal disinfectant. Background technique [0002] In emergency rescue missions, more and more high-tech equipment and sensitive electronic equipment are used; however, since precision components and sensitive equipment are greatly affected by temperature and humidity, and have weak corrosion resistance, they cannot be used once they are polluted by nuclear, chemical, biological Therefore, research on low-corrosion and insulating decontamination technology for sensitive equipment is a research hotspot in the field of decontamination at home and abroad. [0003] Existing decontaminants such as "three-in-two" water-based disinfectant and "191" disinfectant are highly corrosive and can seriously damage equipment coatings and plastics, so they cannot be used for sensitive equipment. decontamination. At present, there is an urgent need for a low-corrosion, safe and low-c...
