Abstract
The present invention relates to the depollutions of environment and disinfectant field, more particularly to a kind of chlorine dioxide solid releasing agent and preparation method thereof, it is prepared from the following raw materials in parts by weight, 4-26 parts of chlorite, brominated inorganic salt activator 10-65 parts, stabilizer 5-20 parts of passivation, hypobromous acid is initially formed in acid condition using tasteless brominated inorganic compound again to activate sodium chlorite, since hypobromous acid is stronger than hypochlorous acid oxidization ability and does not generate chloroform, and then quickly generate high-purity, it the chlorine dioxide of high yield and is influenced by temperature and reaction time smaller, secondary pollution is not generated in use process, the present invention does not generate chlorine taste in production preparation process, production environment and the influence to worker's health can be effectively protected, the bromine-containing compound generated in activation process is higher than chlorine-containing compound oxidation susceptibility, therefore this Invention is lower using concentration, and Disinfection Effect is more preferable, and application range is wider.
Description
Technical field
The present invention relates to the depollution of environment and disinfectant field more particularly to a kind of chlorine dioxide solid releasing agent and its preparations
Method.
Background technique
It is known that chlorine dioxide is the World Health Organization, the generally acknowledged A of food and agricultural organization1Grade disinfectant, due to chlorine dioxide
Belong to that forth generation is nuisanceless, green disinfectant, have a wide range of application model, has obtained domestic and international attention, and demand is growing.At present
The country prepares the existing method of chlorine dioxide solid releasing agent, mainly using sodium chlorite as host agent and hypochlorite production preparation
Chlorine dioxide solid releasing agent, reaction mechanism are main are as follows:
1, hypochlorite activation method: 2ClO2 2-+ClO-+2H+=2ClO2+Cl-+H2O
In the world, German Ji Luo chemical company, Germany prepares chlorine dioxide solid releasing agent using the production of over cure acid group, reacts
Mechanism is as follows
2, over cure acid group method: ClO2 2-+S2O8 2-=4ClO2+SO4 2-
Both the above production method respectively has excellent lack: hypochlorite method: (1) generally having sodium dichloro cyanurate, sym-closene
Equal organic chlorides will cause cyanuric acid residual, and having side reaction causes to have impurity chlorine to generate to form chloroform, cyanuric acid
It will cause secondary pollution with chloroform, increase " carcinogenic " risk.It adds organochlorine or inorganic chloride material chlorine taste is bigger, to production ring
Border and the harm of worker's health are larger.Chlorite's activation method activation rate is lower (generally 80% or so), easily causes chlorous acid
The sodium wasting of resources.The chlorine dioxide solid releasing agent degree of safety of hypochlorite activation method preparation is not easy to control, and loss late is larger,
It can only generally save 1 year, have great unstable factor and safety hidden storage, the transport of chlorine dioxide solid releasing agent
Suffer from.(2) chlorine dioxide of over cure acid group method, activation is pure, and rate of release, activation rate are influenced to compare by temperature, reaction time
Greatly, slowly, activation time is longer, much the field discharged rapidly is required to be difficult to promote, in addition persulfuric acid for release at normal temperature
Root method higher cost is unsuitable for promoting.Described in synthesis: the method that both the above production prepares chlorine dioxide solid releasing agent, in life
It produces and use aspect is not suitable for promoting, the existing production of effective solution of the present invention prepares chlorine dioxide solid releasing agent and producing
With the deficiency used.
Summary of the invention
It is an object of the invention to overcome deficiency in the prior art, a kind of chlorine dioxide solid releasing agent and its system are provided
Preparation Method, the invention be initially formed in acid condition using tasteless brominated inorganic compound hypobromous acid again to sodium chlorite into

Specific embodiment
In following embodiment, the principle that chlorine dioxide solid releasing agent meets water release is as follows,
a、5Br - + BrO3 -+6H+=3Br2+3H2O
b、Br2+H2O=HBr+HBrO
c、2ClO2 2-+BrO-+2H+=2ClO2↑+Br-+H2O
There are following characteristics during release,
1, entirely release process is generated without chlorine, so that the pure free from admixture of the chlorine dioxide released；
2, hypobromous acid is released during release, since the oxidability of hypobromous acid is greater than hypochlorous acid, so than conventional oxychloride
Method conversion rate is fast and high conversion rate, and obtained purity of chlorine dioxide is high, and effect is good, without bad residual；
3, releasing chlorine dioxide needs three steps to complete, and extends reaction process, and each component in reaction equation is anhydrous
It participates in not chemically reacting under dissolution, passivation stabilizer plays the role of passivation in the present invention and stablizes each component, makes
Product safety, the stabilization of preparation must be produced；
4, each component in invention is dry inorganic salts, so the chlorine dioxide that production preparation process and production prepare
Solid releasing agent is tasteless, solves exhaust emission, protects the health of direct labor.
5, when adding anhydrous sodium metasilicate, since anhydrous sodium metasilicate itself has washing function, it can enhance to help and wash function,
When adding anhydrous hydroscopic high-molecular resin, anhydrous hydroscopic high-molecular resin can ClO 2 solution after adsorption activation, then
Slowly volatilization again, can be made slowly-releasing chlorine dioxide solid releasing agent, add anhydrous magnesium chloride, anhydrous calcium chloride, sodium carbonate, carbonic acid
When magnesium, have the function of rapid effervesce, chlorine dioxide can be discharged rapidly, effervesce or quick-acting chlorine dioxide solid releasing agents can be made,
The disinfection and purification that can be used for water body, space, soil, utensil according to function difference, be widely used in health care, food processing,
The environment of all trades and professions such as fresh-keeping of vegetables, agricultural planting, animal husbandry and fishery cultivation, water process, civilian home life, food and drink, cleaning
It administers.
In following embodiment, each feed moisture content is below 0.5%, controls 20-26 DEG C of environment temperature in preparation process,
Relative air humidity 10-30% is controlled, tablet press machine pressure is controlled in 20-28kN.
It is mixed in step 1, selects V-type anticorrosion mixing machine, revolving speed 12-16r/min mixes 15-20min；
