Abstract
The invention provides a method for preparing a high-stability chlorine dioxide aqueous solution disinfectant, and belongs to the disinfectant manufacturing sector. A phosphorous salt compound, uric acid and the derivative compound thereof are added to the chlorine dioxide aqueous solution to improve the stability of the aqueous solution. According to the measurement result, the stability decreasing rate of the chlorine dioxide aqueous solution at a constant temperature of 54 DEG C for 14 days is only 9%. The disinfectant has the advantages of simple preparation, good performance, low cost, wide application and good market prospect. The disinfectant is characterized in that the weight ratio of the phosphorous salt compound, the uric acid and the derivative compound thereof is 100:(0.0001-20):(0.0001-20). The preparation method comprises adding the phosphorous salt compound, the uric acid and the derivative compound into the prepared chlorine dioxide aqueous solution; and intensively mixing to obtain the finished product.
Description
[technical field]
The present invention further handles the aqueous solution of chlorine dioxide that has prepared, and its stability is greatly increased, and belongs to the thimerosal manufacturing industry.
Background technology
Aqueous solution of chlorine dioxide is very unstable, the aqueous solution of chlorine dioxide of 1000ppm, in open-top receptacle, preserve, it in a couple of days complete obiteration, chlorine dioxide aqueous solution disinfectant is greatly affected on using, solid or liquid disinfectant all are contact and bring into play its disinfective action with the form of its solution with bacterium or virus at last in addition, so it is most important in the application of sterilizing to strengthen the stability of aqueous solution of chlorine dioxide.
The manufacture method that the purpose of this invention is to provide a kind of ClO 2 solution of high stability, in aqueous solution of chlorine dioxide, add 0.0001%～20% phosphorous salt compounds and 0.0001%～20% urea and derivatives quasi-compound thereof stirs through my lot of experiments proof, the container of packing into, sealing, preserve in cool place place, can preserve 1 year and do not lose its Disinfection Effect.
Summary of the invention
The manufacture method that the purpose of this invention is to provide a kind of high stability ClO 2 solution, promptly add phosphorous salt compounds and uric acid and derivatives quasi-compound thereof in the ClO 2 solution that has prepared and improve its stability, the technical scheme of technical solution problem of the present invention is such.
One, the material of manufacture method, ratio and step
1, its manufacturing material: comprise aqueous solution of chlorine dioxide, phosphorous salt compounds, uric acid and derivatives quasi-compound thereof, its weight ratio is 100: 0.0001～20: 0.0001～20.Its first characteristics are to add phosphorous salt compounds and uric acid and derivatives quasi-compound thereof.
2, its second characteristic is manufacturing steps: stir add phosphorous salt compounds and uric acid and derivatives quasi-compound thereof in proportion in aqueous solution of chlorine dioxide after, get product.
Two, the combination material of high stable chlorine dioxide aqueous solution disinfectant
1, chlorine dioxide
Molecular formula: ClO
2
Character: yellow green gas, penetrating odor is arranged, the solvability in the time of 20 ℃ in water is 0.0029, and is extremely unstable, explosive is volatile, easily decomposes, and strong oxidation is arranged, and makes the sterilization bleaching agent and uses.
2, phosphorous salt compounds
For example: sodium hexametaphosphate [68915-31-1]
Molecular formula: (NaPO
3)
12～13Na
2O
Character: water white transparency solid or white powder, to inhale easily and ridicule, water soluble, solution are that alkaline PH is about 8.5,628 ℃ of mp.
Purposes: water softener, take a picture printing and dyeing.
3, uric acid and derivatives quasi-compound thereof
For example: uric acid [69-93-2]
Molecular formula: C
5H
4N
4O
2
Title: 2,6, the 8-trihydroxypurine
Structural formula:
Character: white crystals, odorless, tasteless, water soluble is insoluble to ethanol, ether, m.p, 300 ℃, proportion 1.89.
Purposes: pharmacy, analytical reagent.
Three, the mechanism that improves aqueous solution of chlorine dioxide stability is inferred
1, some phosphate can form behind the long-chain more circlewise, thereby helps cage and live in ClO
2Molecule [1].
2, the loop configuration of purine or similar purine helps " entangling " ClO
2Molecule, the electron cloud of its delocalizationization also help the O very strong with electronegativity, and Cl forms stronger intermolecular force.
Four, advantage of the present invention
1, the present invention greatly strengthens the stability of aqueous solution of chlorine dioxide.For example chlorine dioxide concentration is the solution of 500ppm, adds in proportion behind some phosphorous salt and uric acid and the derivative thereof under 54 ℃, and constant temperature was deposited 14 days, effective ingredient ClO
2Rate of descent be 9%, the shelf-life can reach 1 year, is far superior to " 84 liquid " and other like product (see Table 1 and table 2).
2, production technology is simple, and production cost is low, has fabulous market competition advantage.
3, easy to use, of many uses.

[description of drawings]
Further set forth manufacture process of the present invention below in conjunction with description of drawings and individual embodiment.
Accompanying drawing is fabrication process flow figure of the present invention.
[embodiment]
Embodiment:
Get chlorine dioxide content and be 100 kilograms of the aqueous solution of chlorine dioxide of 500ppm, add 50 gram sodium hexametaphosphates,, add 10 gram uric acid again, stir, promptly obtain finished product, deposited two months in fish farm, Hunan, lake, to go again to use, effect is fine.
