Description
Technical field
The invention belongs to antibiosis and sterilization agent technical field, be specifically related to chlorine dioxide generating agent of a kind of monobasic packing and preparation method thereof.
Background technology
Chlorine dioxide is a kind of novel disinfectant, and be a kind of water-soluble strong oxidizer, oxidability is 2.63 times of chlorine, there is efficient sterilizing ability and decolouring and deodorizing function, can kill the bacterium in water body and gas, and can not produce carcinogenic, teratogenesis and cause projecture matter, therefore in developed country, be widely applied.Disinfection agent of chlorine dioxide by internationally recognized be function admirable, effective disinfection sanitizer, food preservative and water quality cleansing agent.
At present, the preparation method of chlorine dioxide mainly comprises chemical method and two kinds of methods of electrolysis, and wherein chemical method can be divided into again sodium chlorite method and sodium chlorate method.With sodium chlorite (NaClO
2) method that produces chlorine dioxide for raw material mainly contains acidization, chlorine oxidation process, persulfuric acid radical ion oxidizing process, electrochemical process, organic matter and transiting metal oxidation method, the hydrochloric acid of wherein take reacts with sodium chlorite prepares chlorine dioxide as example, and its cardinal principle is: 5NaClO
2+ 4HCl=4C1O
2↑+5NaCl+2H
2o.But the method, because the acid of required use in reaction is liquid acid, therefore uses inconvenience, and has certain danger.
At present, when producing solid chlorine dioxide releasing agent, major part is that sodium chlorite and solid acidifier are separated to packing, prevents that it from just reacting before use, discharges chlorine dioxide, causes product failure.But this two-component packaging use procedure more complicated, need to allocate according to ratio during use, and general two-component packaging disinfectant need to be rendered to and in water, reacts or its acidulant is liquid acid.
Publication number is that the patent documentation of CN101176469A discloses a kind of disinfection agent of chlorine dioxide and preparation method thereof, comprise stabilizing agent and activator, described stabilizer package is containing sodium chlorite 62～74%, sodium chloride 8～12%, sodium bicarbonate 7～11%, calcium chloride 2～2.5%, sodium carbonate 7.5～11.5%, and activator is that concentration reaches 4～6% hydrochloric acid.This disinfectant needs two-component packaging equally, stabilizing agent and activator need to be added to use simultaneously, carries inconvenience.
The direction of research is changed to monobasic packing by two-component packaging gradually now, so the types such as monobasic powder packaging, monobasic tablet and monobasic granule have appearred comprising in disinfection agent of chlorine dioxide.But produce the reaction condition that a monobasic packing solid chlorine dioxide disinfectant difficult problem is to control sodium chlorite and solid acidifier, and suitable solid acidifier and passivator, after it is mixed with sodium chlorite, under non-service condition, do not react, and only need change condition and can directly react without additional reactant need to use time.
Publication number is that the patent documentation of CN1439268A discloses a kind of solid-state stabilized chlorine chlorhexidine-containing disinfectant, it adopts organic polymer to be coated sodium chlorite, make coated parent, with anhydrous magnesium sulfate and calcium chloride, coated parent is carried out to Passivation Treatment again, finally mix with composite exciting agent, realized the isolation passivation of material in packaging bag, during use, disinfectant has been dissolved in the water.But this disinfectant needs to use a large amount of anhydrous magnesium sulfates and calcium chloride as passivator in manufacturing process, nullified composition increases, caused the increase of cost, and must be thrown in water when using this disinfectant, just can discharge chlorine dioxide, thereby limit the range of application of this disinfectant.
The patent documentation of publication number CN1449991A discloses a kind of preparation method of chlorine dioxide generating agent, comprise: after sodium chlorate or sylvite, solid acid, water absorbing agent, catalyzer and stabilizing agent are mixed, granulation agent, pulvis or tablet, very easy to use.The weak point of the method is: in course of reaction, can produce CO
2although, CO
2preservation is produced to certain effect, but work as CO
2too high levels, will suppress fruits and vegetables respiration.
Publication number is the preparation method that the patent documentation of CN101172579 discloses a kind of chlorine dioxide generating agent, comprising: after 1:1～1:20 mixes in mass ratio with citric acid by sodium chlorite, then this chlorine dioxide generating agent is prepared into pulvis or tablet.This chlorine dioxide generating agent is easy to carry, be applicable to family and sterilization use among a small circle, but composition forms simple, and because sodium chlorite and citric acid have hygroscopy, if directly sodium chlorite and citric acid are mixed, make tablet or powder, be easy to make sodium chlorite and citric acid after moisture absorption, to lose efficacy in air.
Summary of the invention
The invention provides a kind of chlorine dioxide generating agent and preparation method thereof, this propellant does not need to drop in water to use, and easy to carry, release time is long.
A chlorine dioxide generating agent, by weight percentage, consists of: sodium chlorite or potassium chlorite 12～15%, passivator 28～43%, hygroscopic agent 12～15% and a water p-methyl benzenesulfonic acid 28～43%.
The present invention is using the solid acidifier of a water p-methyl benzenesulfonic acid in chlorine dioxide generating agent, it is a kind of organic acid that does not possess oxidisability, easy deliquescence, can be in the situation that ambient humidity be lower, utilize the reaction of moisture in environment to discharge chlorine dioxide with sodium chlorite or potassium chlorite, without external adding water, participate in reaction.In propellant, add passivator to stop a water p-methyl benzenesulfonic acid under non-service condition, to react inefficacy and the loss that discharges gas and cause propellant with sodium chlorite or potassium chlorite, and the hygroscopic agent adding can accelerate the reaction velocity of propellant under service condition simultaneously.
The burst size of chlorine dioxide is controlled by ambient moisture and the passivator adding and the amount of a water p-methyl benzenesulfonic acid, chlorine dioxide generating agent in the present invention, by weight percentage, be preferably: sodium chlorite or potassium chlorite 12～13%, passivator 37～43%, hygroscopic agent 12～13% and a water p-methyl benzenesulfonic acid 33～38%.More preferably: sodium chlorite or potassium chlorite 12.5%, passivator 37.5%, hygroscopic agent 12.5% and a water p-methyl benzenesulfonic acid 37.5%.
