Description
Technical field
The invention belongs to the disinfection by chlorine dioxide technical field, be specifically related to a kind of binary reaction type solid preparation of chlorine dioxide that is formed by combining alkali metal such as sodium chlorite or alkaline earth metal chlorite, solid acid and other promoter.The invention still further relates to the preparation method of this solid pharmaceutical preparation.
Background technology
Chlorine dioxide is as a kind of water-soluble strong oxidizer; Has sterilizing ability efficient, wide spectrum; And can the oxidation Decomposition bacterium, amino acid and other reducing substanceses in microorganism such as virus and the protein, can also react with organic matter and multiple inorganic ions; And, be product with respect to other chlorine, can not produce organohalogen compounds such as aberration inducing, carcinogenesis, mutagenic chloroform during chlorine dioxide antiseptic, the effect of kill virus, bacterium, deodorizing, bleaching etc. is Cl
22.5 times, The World Health Organization (WHO) classifies its safety as the A1 level.Based on the oxidation and the sterilization idiocratic of chlorine dioxide, it also can be used as the bleaching agent of industries such as paper pulp, weaving; The disinfection sanitizer of food and drink, health, epidemic prevention etc.; The air purification agent of living room, toilet, automobile etc.; The algicide of Treatment of Industrial Water, drinking water treatment and Treatment of Sludge and water treatment agent.
But in actual use, because gas chlorine dioxide character is unstable, is difficult to process Compressed Gas, and has blast characteristics, inconvenience is transported and is stored, and the liquid chlorine dioxide is volatile again, is difficult for concentrating, so has limited the use of chlorine dioxide.And the stable ClO 2 solution moisture is big, and chlorine dioxide active ingredient is low, need add acidic activator during use and could use; Simultaneously, activator species is different, and usage amount is different, causes the difference of activation effect, and sterilization effect is caused negative effect in various degree.Moreover though there is chlorine dioxide generator on the market, the generator cost is high, be inappropriate for small sized applications such as civilian, and Operation and Maintenance needs the professional.It is thus clear that, no matter be gas chlorine dioxide or stable ClO 2 solution, all bring many inconvenience in transportation, storage with in using.In order to overcome this limitation, the product of chlorine dioxide solid form arises at the historic moment.
Solid preparation of chlorine dioxide is meant under certain operation condition can discharge ClO
2The solid, shaped goods of gas, these products can be the solid, shaped of colloid, lotion, Powdered, tablet, agglomerate and other different shapes.The type preparation generally is to be that primary dose, organic solid acid or mineral acid material etc. are that the primary raw material of acidulant is prepared from chlorite or stable ClO 2 solution.With respect to other forms of chlorine dioxide, solid chlorine dioxide is simple to operate except having, ClO
2Outside content height, stable in properties, transportation and the advantage such as easy to use, also have some specific functions sometimes, for example slow-release function etc.
Different by preparation method and principle and preparation function, solid preparation of chlorine dioxide generally can be divided into three types of absorbent-type, response type and spacetabs types.
1, absorbent-type solid chlorine dioxide.
The preparation of absorbent-type solid chlorine dioxide is simple, is the ClO that at first produces higher degree generally speaking
2Gas absorbs chlorine dioxide with the aqueous solution that contains stabilizing agent then, obtains stable ClO
2Solution, last, utilize some these solution of solid absorbent absorption.
When the preparation of absorbent-type solid chlorine dioxide; Adsorbent as the solid chlorine dioxide carrier should have bigger adsorption capacity, bigger specific surface and bigger particle diameter, and the pH value of adsorbent preferably is controlled between the 8.5-9.0; Solution premature decomposition to avoid adsorbing discharges chlorine dioxide.Absorption carrier can be divided into two big types, and one type is inorganic adsorbent, can adopt porous materials such as silica gel, calcium silicates, diatomite, talcum powder, molecular sieve and active carbon.Another kind of is organic adsorbent, like high-hydroscopicity polyacrylic acid resin, agar, superpower polymeric adsorbent, carboxymethyl cellulose etc.
In the process of preparation the type solid pharmaceutical preparation; Need the highly purified chlorine dioxide of prepared beforehand; Because the high concentration of gas chlorine dioxide and the strong oxidizing property of chlorine dioxide, etching apparatus is higher to equipment requirements easily; In case and leaking appears in equipment in suitability for industrialized production, with the serious threat workers'health.When preparation absorbent-type chlorine dioxide preparation, need to consider to select suitable adsorbing medium and stabilizing agent, reach requirement to guarantee the solid pharmaceutical preparation that makes.
This formulation also need add activator in use and discharge to impel chlorine dioxide.This just requires on the packing of product, to adopt binary or polynary packing, during use use is mixed in the water-soluble respectively back of two kinds of components, and once Kaifeng; Need once use up; Otherwise be prone to lose efficacy, cause the significant wastage of product, increase the working concentration and the disinfection cost of product.In addition, the activator that adds during use is excessive, can cause that pH value of solution is too small, causes secondary pollution.
The adsorbent that said preparation adopts particularly organic adsorbent has bigger adsorption capacity, meets water and is prone to expand.So require the type preparation preserve, should strict control its environment, particularly ambient humidity in the accumulating, lost efficacy in case product is met water (or big steam) in placement.
2, response type solid chlorine dioxide.
The response type solid chlorine dioxide is that different solid reaction raw materials is mixed according to a certain percentage, makes it directly to take place chemical reaction slowly, in the long time, discharges chlorine dioxide.Add the water of certain multiple when this series products uses or place the bigger environment of relative moisture can accomplish chemistry or priming reaction at short notice product, discharge the active ingredient chlorine dioxide.As add stabilizing agent in the preparation, add and then can be mixed with stability chlorine dioxide behind the water and use.
In the preparation of response type solid pharmaceutical preparation, the chloride that the someone proposes in the raw material thing, to add alkali metal or alkaline earth metal utilizes its water absorbing properties to reach dry purpose as passivator.This passivation means cause product unstable because the passivator water imbibition is strong, and the holding time is short, particularly one open bag inefficacy soon.
Adopt embedding method that the raw material thing is coated and can obtain effect preferably, but actual production with use in should be specifically noted that character and the embedding of covering after to the factors such as influence of environment.In some technology, need at first carry out the preparation of clad material, more obtained material is coated on the sodium chlorite surface, not only complex process, and equipment drops into high.And, influence the solvability and the solute effect of final products owing to the covering poorly water-soluble that uses.Also can cause solid insoluble ratio rising in the product on the other hand, the covering of dissolving also can cause the pollution of water quality.
3, slow-release solid chlorine dioxide.
The slow released ClO 2 solid pharmaceutical preparation is meant and can slowly discharges ClO
2The solid pharmaceutical preparation of gas, its rate of release wants much little than adsorptivity and response type solid pharmaceutical preparation, and said preparation generally is divided into gel-type and powder-type.Say absorbent-type and response type ClO on the stricti jurise
2The solid pharmaceutical preparation product all has slow release ClO
2The function of gas.
Spacetabs type ClO
2Solid pharmaceutical preparation (adsorptivity) is to utilize the absorption property of solid absorbent, with stable ClO
2Solution absorbs is mixed with solid acidifier again, makes it reaction, discharges ClO slowly, constantly
2Gas is used for sterilizing, air cleaning, deodorizing and fresh-keeping etc.Solid acidifier can be a solid peracid, or adsorbs a kind of generation H
+Acid or a kind of ackd salt, comprise citric acid, ferric trichloride, aluminum sulfate, tartaric acid etc.In the preparation use,, can control ClO in several ways in order to reach certain application target
2The burst size of gas is for example controlled the addition of solid acid or the intensity of acid etc.
Spacetabs type ClO
2Solid pharmaceutical preparation (reactivity) is with solid NaClO
2Or other primary dose put together with solid acidifier, adds other assistant agent, makes it to slow down ClO
2Rate of release, reach the purpose of slow release.This series products can be processed paste, gel, powdery, is positioned over suitable place, has sterilizing, air cleaning, deodorizing and function such as fresh-keeping equally.
Spacetabs type ClO
2Solid pharmaceutical preparation has certain application value, and the space disinfectant that in real life, can be used as living room, automobile, toilet and other occasions uses, and has bigger development space.But in practical application, should be specifically noted that how to control the gas chlorine dioxide concentration that said preparation discharges, to guarantee within effective threshold value.
