The invention belongs to a kind of production method of disinfection agent of chlorine dioxide.
In the sterilizing agent that people use always, the sterilisation effect of chlorinated product is good, is the thimerosal of major ingredient as chlorine, clorox, Losantin and various hypochlorous sodium, and the main drawback of these sterilizing agents is to produce carcinogenic organochlorine compound; Decompose more, cannot say for sure to deposit; There is the chlorine foul sewage to dye to being sterilized object.Dioxide peroxide is a kind of strong oxidizer, and sterilisation effect is good.But because the difference of chlorine dioxide generation, product purity is not high, there are deleterious impurity and product instability in the product, cannot say for sure to deposit, preparation method as the disclosed dioxide peroxide of CN10165018, be to make reductive agent with methyl alcohol, by reacting under the high acidity in the isolating reaction zone on a structure, and reaction product is discharged among a large amount of recirculation sodium chlorate solutions by this district.Thereby the dioxide peroxide that produces is less for chlorine stains, and purity is higher; CN101365718 is disclosed to be that the on-the-spot method for generation of a kind of dioxide peroxide is difficult for the preservation problem to solve dioxide peroxide.But the common root problem that exists of above-mentioned technology is the product instability, cannot say for sure to deposit.Therefore need development a kind ofly both not have poisonous impurity, processing unit is simple, and the stable chlorine dioxide generation of being convenient to preserve of product.
The present invention is intended to solve the preservation problem of the problems referred to above, the especially product that exist in the disinfection agent of chlorine dioxide production.
The technical scheme that realizes the object of the invention is: the production method of stability chlorine dioxide is to make reductive agent with hydrogen peroxide, reduction production of sodium chlorate dioxide peroxide in sulfuric acid medium, the amount ratio of sodium chlorate, sulfuric acid and three kinds of raw materials of hydrogen peroxide is 1: 1～4: 0.3～1.5, sodium chlorate elder generation is dissolved in the water in 1: 1～3 ratio, three kinds of raw materials are added drop-wise in the reaction vessel simultaneously then, the volume ratio of three kinds of raw material droppings is 3: 4: 1, the dioxide peroxide that reaction produces absorbs with 5% sodium carbonate solution, and absorption reaction is controlled under 20～30 ℃ of temperature condition and carries out.
Be described in further detail the present invention below.
The raw material of production stability dioxide peroxide of the present invention is sodium chlorate, sulfuric acid and hydrogen peroxide, and is earlier in 1: 1～3 ratio that sodium chlorate is soluble in water, fully stirs, and treats to dissolve fully the back and opens the vacuum valve that leads to the sodium chlorate test tank, and solution is evacuated to high-order test tank;
98% sulfuric acid of weighing is on demand opened and is led to sulphur acid meter measuring tank vacuum valve, takes out the sulfuric acid of requirement with the loss of weight method and goes into test tank;
H in the ratio weighing 30% of raw material
2O
2, it is an amount of to add 10% concentration dilute sulphuric acid, and example goes into to hold H
2O
2End opening and in;
The sodium carbonate solution of joining content 5% places the two-stage tourie.
Open the absorption system vacuum valve, (the surge tank vacuum degree control is at 0.04～0.046MPa to treat vacuum tightness to reach requirement, the tourie vacuum degree control begins 0.07～0.08MPa) time to retort reinforced, notices when reinforced that three kinds of raw materials drip simultaneously, the CLO that reaction produces
2Be evacuated to tourie by negative pressure,, absorb, in absorption liquid, also can add certain amount of H before the start with yellow soda ash through the two-stage tourie
2O
2Make catalyzer, generally in 1 ton of yellow soda ash, add 3 liters H
2O
2, to improve the absorption rate of dioxide peroxide.
With sodium chlorate, sulfuric acid and hydrogen peroxide is that the chemical equation of raw material production dioxide peroxide is as follows:
①+②+③+④
From above-mentioned reaction formula, should avoid 4. the carrying out of formula reaction, therefore to control the rate of addition of hydrogen peroxide, and NaCLO
3And H
2SO
4Rate of addition should be fast slightly, thereby make HCLO
3Concentration excess drips H like this
2O
2After, the HCLO of generation
2Immediately with HCLO
3Reaction generates CLO
2, as H
2O
2Drip too soon, 4. formula reaction takes place, and blasts easily, and produced simultaneously HCL will consume more absorption liquid, and when therefore three kinds of raw materials dripped simultaneously, the volume ratio of dropping should be controlled at was advisable at 3: 4: 1.
The absorption reaction temperature should be controlled at 20～30 ℃, and the low absorption liquid that is beneficial to of temperature absorbs, thereby the cooling of tourie employing cold water, when temperature is high, opens the cooling of cooling water control valve.When reinforced stopping, also should continuing to absorb 1～1.5 hour, it is more complete that dioxide peroxide is absorbed.
The stability chlorine dioxide that the inventive method is produced is a kind of white (colourless) or utmost point light yellow transparent liquid, pH value about 8.6, content is 2.0～2.5%, according to service requirements, can adopt different activation methods, activate with mineral acid, release rate is fast, be suitable for tap water, the sterilization of vessel etc., as use hydrochloric acid activation, can mix product with 36% HCL in 100: 1～5 ratio, activation rate can reach 95% in 1 minute, when fresh-keeping, and available SOLID ORGANIC acid activation, release rate is slower, the organic acid consumption is 5～20%, and as activating with 10% citric acid, activation rate can reach 26% in 3 minutes.The agent of this effect product sterilization is used for vessel when sterilization, dilutes 200 times, vessel is immersed in the thimerosal of dilution 2～3 minutes and gets final product, and is used for drinking water disinfection, dilute 20000 times capable of direct drinking.
Stability chlorine dioxide compares with similar sterilizing agent, have the advantages that consumption is little, effect is fast, the ability of killing is strong, Pulogene product as the U.S. emerging pharmaceutical factory of lily also is a kind of disinfection agent of chlorine dioxide, this product 50PPM, 5 minutes is 100% to colibacillary killing rate, and this product 3.125ppm only, killing rate was 100% in 5 minutes.Be used to kill hepatitis B surface antigen, using 500ppm5 minute killing rate of Pulogene product is 98.87%, and stability chlorine dioxide 500ppm, killing rate reached 100% in 3 minutes.
The dioxide peroxide produced of the present invention absorbs with alkaline matter in sum, thus product property stable, easily preserve, be stored in the sealed plastic container, effective constituent is declined by less than 5% in the room temperature next year, consumption is little, effective, effect fast; And do not have carcinogenic at malicious impurity, so safety non-toxic; But in disinfectant deodorizing simultaneously, eliminate the unusual smell and residual chlorine is not smelly; Be not only sterilizing agent efficiently, and can be used as sanitas and preservation agent.
