Description

The stable composition of HOCl, it produces and using method

The present invention relates to stable hypochlorous acid (HOCl), its production method and the various application for the described composition of use.

Fully set up in this area and use sterilizing and antiseptic solution except degerming, virus or fungal contamination.Sterile solution, disinfectant and bleaching agent are routinely for providing aseptic or the environment of sterilization.Such as wherein patient and/or environment to infect and cross-infection sensitivity environment (such as medical treatment, animal doctor, agricultural, food processing and dentistry) in, such application particular importance.Be used for surgical intervention or human or animal's health when equipment other get involved and crop process, fresh food produce and water treatment time, need pathogene to destroy.

Recognize, due to the common environmental infection (such as methicillin resistant Staphylococcus aureus (MRSA that hospital brings, Methicillin-resistant Staphylococcus aureus) and Clestridium difficile (Clostridium difficile)) raising of incidence, provide aseptic and the environment of sterilization and equipment have become more important.

Hypochlorous acid (HOCl) has been known as the effective antimicrobial of activity with directed toward bacteria, virus, fungi and spore in the art.It is particularly advantageous for medical treatment, animal doctor, agricultural and commercial Application, because it is not containing oral toxicity, skin sensitivity or stimulation (comprising Ocular irritation) and for non-mutagenic.

But, there is many problems relevant to using hypochlorous acid.Particularly, the solution of HOCl is very unstable, has the short half life period of about 48 hours.Therefore, solution loses their antimicrobial acivity fast, therefore loses their effect.The current solution of this problem is the electrolysis utilizing saline solution, and original position prepares HOCl solution as required.This needs field apparatus to prepare solution, obtains the nonactive lean solution that the high cost relevant to preparing HOCl solution is relevant with the half life period short with it.Electrolysis is also a kind of slow and expensive method, and it may change, and is difficult to (if not can not) and comes into force.

Oxidant (such as chlorine, bromine and chlorine dioxide) is widely used as highly effective antimicrobial, but shortcoming is extended storage stability in aqueous solution.When chlorine and bromine, pH also has material impact to general active species, and it affects both effect and bleaching properties.

United States Patent (USP) 2,438, relates to the stable of hypochlorite solutions 781 (on March 30th, 1948) and quotes the product be suitable for used as stabilizers in the solution of alkali metal hypochlorite, because herein is provided the shelf life of prolongation.Based on weight, prove that benzene N sodium-sulfonamide provides maximum stability.The antimicrobial efficacy with various degree that stable halogen forms like this produces certain limit instead of the halogen of the combination of microorganism thing class clearly limited.

For the control of microorganism and bleaching, at United States Patent (USP) 3,749, the solution using buffer to carry out stable N-halogenated compound was described in 672 (on July 31st, 1973), wherein by adding hypochlorite in some N-hydrogen compound (such as sulfamic acid), preparation pH is the aqueous solution of 4-11.PH stablized by buffer is 4-11, and in alkaline pH, dominant class is hypochlorite anion instead of highly effective hypochlorous acid.

United States Patent (USP) 6,162, relate to the aqueous solution of the source of single positive chlorion (unipositivechloride ion), chlorine stabilizing agent, acid buffer agent 371 (on December 19th, 2000), with stable pH for 2.0-6.5, wherein the mol ratio in the source of chlorine stabilizing agent and single positive chlorion is greater than 1:1.But can release chlorine in acid condition according to the Raman spectrum said composition such as (D Cherney people, 2006), and not attempt to control chlorite level, owing to using clorox, chlorite level is high inherently.

The another kind of mode improving the shelf life is the composition forming drying regime, as described in WO/1991/003936, wherein, said composition contains water-soluble inorganic halide, strong oxidizer, in aqueous solution, described strong oxidizer and halide reaction, to produce hypohalogenous acids radical ion and enough sulfamic acids being used as halogen acceptor.Water soluble carbonate or bicarbonate and excess of ammonia base sulfonic acid react and are used for effervesce (effervescence) to produce carbonic acid gas.But, do not require that aqueous solution is steady in a long-term.

Compared with unstable halogen, the derivative of N-hydrogen compound (such as 5,5-dimethyl hydantoins) and their chlorination has proved the stability with improvement, and this technology is widely used in such as mucus control field in paper mill.The form of combination and intermediate (such as monochloro hydantoins) discharge halogen according to demand instead of use high-purity hypochlorite solution based on preparation.United States Patent (USP) 6,471, relate to for 974 (on June 29th, 1999) via buffering and use enhancing adulterant (such as 5,5-dimethyl hydantoin), there is the N-chloro amido sulfonate composition (N-chlorosulfamate compositions) of the microbial activity of enhancing, it causes the halogen thing class of certain limit, and from the angle of end user and management, halogen thing class is less desirable.In addition, low pH can cause producing chlorine, and does not attempt chloride ion content is minimized.

Hypochlorous acid (HOCl) is weak acid, there is hypochlorous acid when chlorine is dissolved in the water.In aqueous solution, HOCl partial solution is from becoming anion hypochlorite OCl -.

Cl 2+H 2O<------>HOCl+H ++Cl -

Under pH7.5, there is HOCl and OCl of comparable sodium -, exceed this pH, dominant class is OCl -, and total ionization is there is under pH9.5.

HOCl has been accredited as main biocidal activity thing class.Therefore, owing to falling low-level HOCl, in alkaline environment more, biocidal efficacy reduces (Rideal and Evans1921) and Johns (1934).

By chlorine, liquid sodium or lithium hypochlorite, or HOCl can be produced by powder calcium hypochlorite, dehydration sodium dichloro cyanurate and trichlorocyanuric acid.In clorox and calcium hypochlorite solution, that main existence is hypochlorite ion, and as disinfectant, hypochlorite ion is lower than hypochlorous validity up to 120 times, and by Kapoor, S.K, (1968) prove.

With the little molecular dimension of the HOCl of electroneutral charged couple can rapid osmotic to microbial cell, via the inhibitory enzyme (people such as Knox, 1948), the ATP hydrolysis (people such as Barrette in cell, 1987) DNA replication dna (people such as Rosen, is suppressed, 1998) and the induced protein aggregation (people such as J Winter, 2008), HOCl makes the survivability rapid deactivation of microbial cell.

Fully quote HOCl as proof and kill spore activity (Rudolf and Levine1941), wherein under the pH level of certain limit, use the effective solutions of chlorine of 25ppm, and the B.metiens spore measuring generation 99% kills the required time.Result display is 2.5 minutes for pH6, and being 3.6 minutes for pH7, is 5 minutes for pH8, is 19.5 minutes for pH9, is 35.5 minutes for pH9.35, is 131 minutes for pH10, is 465 minutes for pH12.86.

As mentioned above, generate HOCl by electrochemistry, but its major defect lacks stability required on generator at the scene and pH retentivity.Usually due to very high brine content, also there is perchloride residue, this can cause residual and improve corrosion.

U.S. Patent Application Publication US2009/0258083A1 (on October 15th, 2009) describes a kind of method for the preparation of stable antimicrobial hypochlorite solution, the method, by diluting aging raw material with under the pH scope of 2.8-4.0, provides the HCl solution of 50-7000ppm.Under these pH levels, exist and produce the possibility of chlorine, and be less desirable from the high chloride level of clorox and hydrochloric acid about stability, burn into purity and remnants.

Unpub U.K application number 1021287.6 (people such as Mallet, C) describes containing hypochlorous aqueous solution and salt M nx ythe preparation of stable HOCl solution, wherein M is hydrogen or metal, and X has the conjugate base that pKa is the acid of 4-7, and wherein n and y is 1,2 or 3 independently, and salt M nx yhave overall neutral electric charge, the pH of described composition is 4-7.By keeping the pH of solution in specific scope, said composition has shown its antimicrobial acivity of maintenance and has reached many months.But really need in the composition to comprise salt, this may not always expect.Further preferably can the solution of administration measure, and without the need to halogen stabilizer, such as sulfamic acid.

Fig. 3 and 4 illustrates to reduce chloride content to the distribution curve of the impact that chlorine thing class distributes.

Embodiment 1: the research according to the present invention with the stable HOCl composition of subchloride level

The present invention relates to hypochlorous true stable.Many proposition uses the additive combined with hypochlorite or hypochlorous acid, to form different compounds or compound.These materials it is said stabilizing solution.Therefore, this solution is not pure hypochlorous acid, but has the hypochlorous balance of additive.

Usually there is the chlorine of high percentage as the chlorine combined instead of free chlorine, the hypochlorous acid do not combined that wherein free chloro table is total and hypochlorite.For some additives, the chlorine thing class of combination has slight microbiological activity, for other additives, does not then have microbiological activity.

Add other component and there is obvious result; In some applications, the solids content improving dissolving simply may be harmful to; Some additives are harmful to, and hinder them in the application of water contacting foodstuff or food-contacting surface; If water is used for drinking, medical applications or agricultural application, some is unacceptable.Therefore, the hypochlorite solution that there is pure hypochlorite solution or only there is low-level additive is expected.

Cl 2+H 2O<------>HOCl+H ++Cl -

At the Cl of some fixed concentrations -under, Cl 2, HOCl and OCl -relative scale can be expressed as:

Utilize the formula of the equilibrium constant in equation (1) and equation (2) and pH to equal the relation of the negative logarithm of hydrogen ion concentration, we obtain following formula:

The ratio of each chlorine thing class can be drawn for pH.Fig. 1 of accompanying drawing shows the common distribution of chlorine thing class under the effect of pH.The key feature of this distribution map is:

3) under pH5.5, there is the little but Cl of significance level 2(solution (aq)).

4) time lower than pH5.5, Cl 2(solution (aq)) level improves.Chlorine will be overflowed.

Notice to there is chlorine ion concentration in the equation for generating distribution curve.By setting chlorine ion concentration as variable, the impact that it distributes on chlorine thing class can be observed.Fig. 2 of accompanying drawing describes the impact that chloride concentration improves 10 times.The key feature of this distribution map is:

This figure shows, and in perchloride solution (such as, the hypochlorous acid that electrochemistry produces), hypochlorous acid level is restricted and more easily produces chlorine.

These figure show, and can more easily produce stable hypochlorous acid in subchloride solution.This figure shows, and there is less chlorine, even if at a low ph in subchloride solution; Therefore, the effusion of chlorine is greatly reduced.How low the effusion of chlorine is the critical path that hypochlorite solution decomposes, and can limit the pH of adjustment on sour direction.The present invention has shown can limit the decomposition of this route.

Make pH value of solution be offset to lower pH, reduce hypochlorite concentration, be conducive to hypochlorous acid.Hypochlorous acid can be stablized as mentioned above.Because hypochlorite concentration is much lower, the loss produced because these two hypochlorites decompose route reduces.

Due to for all solutions of chlorine, decomposable process is accelerated by the existence of light, high temperature and metal ion.Therefore, the purity of the raw material of suitably packaging and storage is still important.

If we can reduce chloride content, be only conducive to the stability of hypochlorous improvement in subchloride solution.When the solution of chlorine is by preparation of chlorine, chlorine is dissolved in the water, and hypochlorous acid and the hydrochloric acid of stoichiometric amount such as to obtain.

When producing clorox, chlorine is dissolved in sodium hydroxide, clorox and the sodium chloride of stoichiometric amount such as to obtain.This means, for 14/15% industrial liquor natrii hypochloritis, to there is about 11% sodium chloride.When the chlorine stable by organic procedures is used as the source of chlorine, chloride level is low, but organic backbone molecule may present difficulty in preparation.The phosphate of chlorination also can obtain subchloride solution, but they have high phosphate and chlorine ratio, and this presents the difficulty of himself.They also have high pH.

The present invention preferably utilizes high chlorine and chloride ratio in calcium hypochlorite.Calcium hypochlorite production method relates to the reaction of chlorine and calcium hydroxide slurry.With etc. stoichiometric amount form calcium hypochlorite and calcium chloride.Compared with calcium hypochlorite, calcium chloride is more solvable, is therefore mainly present in saline fluid.Removing saline fluid, to reduce chloride content.Carry out the second chlorination stage, to strengthen hypochlorite concentration, comprise and the solid from the stage is above disperseed again and itself and more chlorine are reacted.When being separated with salt solution by solid, again remove calcium chloride.The method obtains the solid product containing 6-8% calcium chloride and 60-65% calcium hypochlorite.

When calcium hypochlorite is dissolved in the water subsequently, form the alkaline solution of calcium and hypochlorite ion.If prepare solution by sodium hydroxide, chlorine and chloride ratio much higher.Some calcium are as calcium hydroxide precipitation.Removed by isolated by filtration.This solution is still containing the high-caliber calcium needing removing.Use phosphoric acid that pH is adjusted to about 5-6, obtain calcium phosphate precipitation.Again passed through to filter.

Product is intimate pure hypochlorous solution.Use phosphoric acid or sodium hydroxide further as required, pH can be adjusted to the value of expectation.It is beneficial that there is low-level phosphate in the solution to be used as pH buffer.Stability test illustrates any hypochlorite ion that low-level calcium stable exists.

Liquid storage can be used for preparing various product, describes in detail about of the present invention first and the third aspect as above.It is necessary that use deionized water to dilute.Running water and softening running water contain chlorion.Although only exist with relatively low level, subchloride level makes low-intensity hypochlorite solution instability (destabilising).

During one month, test the stability of the present composition, starting composition contains 5000ppm chlorine.The results are summarized in following table 1:

Result display 80% is retained in HOCl, far above the aqueous solution of the non-stable electrolysis-preparation of prior art.

Embodiment 2: prepare stable HOCl solution by the anhydrous composition of the pure calcium hypochlorite of the analysis with 75% and citric acid.

The pure calcium hypochlorite of analysis (such as Arch Chemicals sells) of " x " gram 75% is mixed with " y " gram citric acid, is placed on subsequently in water-soluble non-halogen requirement coating (such as gelatin or gelatine replacement).When with have the water of given volume " z " with pH " A " contact time, under concrete ppm and pH, produce HOCl, as shown in table 2 below.Deionized water is used to realize the pH of 5.5.

3the ppm of the chlorine measured via DPD (diethyl-p-phenylenediamine tablet) (DPD (diethyl-p-phenylenediamine tablets)).
