Description
Technical field
The invention belongs to disinfecting liquid technical field, be specifically related to a kind of manufacturing approach of C5H6Br2N2O2 thimerosal.
Background technology
C5H6Br2N2O2 is as sterilization of new generation, sterilization, algicide; Have efficient, spectrum is wide, power is strong, fast, advantage such as low burn into non-secondary pollution, non-toxic and safe, use be cheap; More and more be widely used in the various fields of human being's production, life, have much the trend that replaces traditional chlorinated product sterilization, disinfection efficacy.
At present C5H6Br2N2O2 is suitable for industrial circulating cooling water processing, agricultural greenhouse plantation, animal husbandry and fishery breed, health care, civilian, public health, waste water treatment, middle water utilizes each field such as processing, drinking water disinfection again.In actual the use; C5H6Br2N2O2 form with hypobromous acid in water discharges bromine; Reaction velocity is exceedingly fast, and in water, constantly discharges bromic acid and reduces the microorganism surface tension, destroys the organic matter diaphragm; Through promoting the protein molecule effect of strong oxidizer and bacterial cell, reach the raising sterilizing ability thereby destroy protoplasm; Just can make the microbial bacterial survival rate be reduced to 0.0001% in 4 minutes, to compare fungicidal effectiveness higher with traditional chlorinated product, and time delay is more lasting.Simultaneously, under the same terms to metal protection 2-4 times less than chlorinated product.In water C5H6Br2N2O2 generate hypobromous acid to microbial action after surplus eliminating minute 5.5-DMH be decomposed into hydrocarbon oxygen compound by light oxygen under field conditions (factors), not because of the residual water body environment pollution that causes, human body is not caused " three cause " result.In fact C5H6Br2N2O2 carries out practical application as disinfectant, at first is to solve its solubility, secondly is the sterilizing ability problem of its aqueous solution of dissolving back, is its stability problem at last.Can not solve above-mentioned three problems, just can't give full play to and utilize the killing action of C5H6Br2N2O2, seriously hinder the use of C5H6Br2N2O2 as disinfectant.
But up to now declare patent and commercially available prod; For example: publication number is the patent of CN102197805A; Experimental data and result in its application paper confirm without authoritative department; The product that practical stability and bactericidal property intersect fails to embody, and does not therefore also possess actual application value.
Though present all kinds of technical schemes have proposed to have the C5H6Br2N2O2 dissolving method and the technology of certain value; But but say or fail to reach mass market running requirement from the Disinfection Effect of its actual thimerosal and stability, laboratory product just at most.Therefore, how solving the solubility of C5H6Br2N2O2, secondly is the sterilizing ability problem of its aqueous solution of dissolving back, is its stability problem at last, becomes the problem that manufacturer and user very pay close attention to.
Summary of the invention
The objective of the invention is to propose that a kind of germicidal efficiency is high, the manufacturing approach of the C5H6Br2N2O2 thimerosal with practical value of good stability.
The manufacturing approach of the C5H6Br2N2O2 thimerosal that the present invention proposes, concrete steps are following:
(1) deionized water that C5H6Br2N2O2 is used is dissolved in preparation:
(2) under 15 ℃ of-50 ℃ of temperature, the compound releasing agent of ND-301 is put into deionized water, stirred 10-30 minute; The compound releasing agent of this ND-301 is used to discharge the C5H6Br2N2O2 sterilizing ability;
(3) the C5H6Br2N2O2 raw material is put into above-mentioned solution, stirred 15-30 minute; Promptly obtain required C5H6Br2N2O2 thimerosal after the filtration, its effective bromine concentration is 200-10000ppm.
Wherein, by weight, the C5H6Br2N2O2 raw material is 0.2 ~ 1, and the compound releasing agent of ND-301 is 0.2 ~ 1, and deionized water is 98 ~ 99.6.
The compound releasing agent of ND-301 that the present invention is used is received ancient cooking vessel water treatment Science and Technology Ltd. production and selling by Shanghai, and ND-301 is the marque of this compound C5H6Br2N2O2 sterilizing ability releasing agent.The main component of this releasing agent is ammonium carbonate, sodium bicarbonate and saleratus, belongs to food grade products.Through detecting the C5H6Br2N2O2 thimerosal that adopts the present invention to make is nontoxic level product (LD
50＞5000 milligrams/kilogram).
The manufacturing approach of the C5H6Br2N2O2 thimerosal that the present invention proposes, selection is simple, and is easy to make, and owing to select the compound releasing agent of ND-301 as the hydrotropy additive, the disinfective action of C5H6Br2N2O2 thimerosal fully realized.When C5H6Br2N2O2 thimerosal concentration of the present invention is 100ppm, be 99.99% to the killing rate of Escherichia coli and staphylococcus aureus; When thimerosal concentration is 400ppm, be 99.99% to the killing rate of withered grass gemma black mutation;
The stability of C5H6Br2N2O2 thimerosal of the present invention, by the method for testing of " disinfection technology standard " (2002 editions), the term of validity can reach more than 2 years.Can be widely used in agricultural greenhouse plantation, animal husbandry and fishery breed, health care, civilian, public health, waste water treatment, middle water utilizes disinfecting of each field such as processing, drinking water disinfection again.
