Without phosphorus javelle water and its preparation method and application
Technical field
The present invention relates to sterilization field, more particularly, to the disinfectant solution field of sodium hypochlorite, particularly to a kind of without phosphorus javelle water and preparation method thereof.
Background technology
Sodium hypochlorite NaClO, English full name sodiumhypochlorite, be a kind of application inorganic salt very widely, is also a kind of strong oxidizer, bleach, disinfectant and deodorant.Aqueous sodium hypochlorite solution is commonly called as drift ice, is the side-product of chlorine industry, and its production technology is simple, cheap, just has very strong sterilizing ability under room temperature, it is simple to use.Liquor natrii hypochloritis is for medical care during the World War I the earliest, and in view of it has the bactericidal property of high-efficiency broad spectrum, it is still widely used in the sterilization of the process of tap water, hospital, diet and family etc., sterilization at present.
Some defects of javelle water ubiquity existed on market: on the one hand, there is due to the hypochlorous acid in solution very strong oxidisability and bleaching power, it is easy to skin is caused corrosion, cause that liquor natrii hypochloritis cannot be directly used to clinic;On the other hand, due to sodium hypochlorite self poor stability, easily decompose, it produced, store, transport, sell and the aspect such as use all brings greatly difficulty and loss.Meanwhile, in order to improve the storage period of liquor natrii hypochloritis, the stabilizer etc. that manufacturer adds in the product can cause environment pollution again.
Improve the stability of industry liquor natrii hypochloritis, it is possible to take in from several aspects such as production technology, the pH value of liquor natrii hypochloritis, the removal of impurity metal ion, condition of storage improvement and extraneous stabilizing agents.Wherein control the pH value of liquor natrii hypochloritis, in liquor natrii hypochloritis, interpolation two kinds of methods of stabilizer are that most convenient is feasible.Due to sodium hypochlorite molecule only when solution weakly acidic pH just with obvious resolution of velocity, and more near acid decomposition is more rapid, and therefore alkalescence is more strong more stable.Research shows that pH value often improves a unit, and sodium hypochlorite decomposition rate declines 20%.So improving total alkalinity is strengthen another Main Means of liquor natrii hypochloritis's stability, but total alkalinity is too high has considerable influence to liquor natrii hypochloritis's result of use again.The too high one side of total alkalinity can reduce the bactericidal activity of sodium hypochlorite, the application that can improve its corrosivity, limit it in skin on the other hand.
Publication number CN1104429 adopts surfactant, Efficacious Disinfeitant, sodium dihydrogen phosphate etc. to improve the stability of liquor natrii hypochloritis;Wherein the addition of sodium phosphate and sodium dihydrogen phosphate is all between 3%~8%, environment can be brought and have a strong impact on, such as wawter bloom.Publication number CN1247707 adopts sodium alkyl sulfonate, sodium alkyl benzene sulfonate, sodium hydroxide to improve the stability of sodium hypochlorite;But owing to it requires pH value of solution >=12, greatly reduce the bactericidal activity of sodium hypochlorite, also improve the corrosivity of solution;Simultaneously as patented product has strong oxidizing property and Bleachability, it is impossible to for clinic.Publication number CN102696675A describes a kind of method adopting amine oxide and organic phospho acid to improve liquor natrii hypochloritis's bactericidal activity, but does not provide the addition how the solving phosphorus method to environmental effect;And the patented product is not suitable for clinic and skin degerming equally.
So a kind of not phosphorous, will not cause environment pollution, simultaneously again can gentle hypochlorite oxidation and improve bactericidal activity and the javelle water of good stability be that extremely there is practical value.
Summary of the invention
One object of the present invention is aiming at above Problems existing with not enough, it is provided that a kind of can gentle sodium hypochlorite oxidisability, improve bactericidal activity, simultaneously environment is not brought again phosphorus pollution, good stability, can be directly used for clinic and skin degerming and long shelf-life without phosphorus javelle water.
To achieve these goals, provide a kind of without phosphorus javelle water in the present invention, be characterized in, including the raw material of following percentage by weight:
Concentration is the sodium hypochlorite 1~60wt% of 10%;
Sodium chloride 0.05~1.0wt%;
Sulfamic acid sodium 0.2~10wt%;
Water-soluble grease 2~18wt%;
Polyvinylpyrrolidone 0.1~5wt%;
6M hydrochloric acid 0.05~1.0wt%;And
Water.
It is preferred that described water-soluble grease is at least one in water solublity grapefruit, water solublity babassu oil, water solublity Semen Maydis oil, water solublity Oleum Cocois, water solublity Oleum Helianthi, water solublity olive oil.
The beneficial effects of the present invention is: the present invention can gentle sodium hypochlorite oxidisability, improve bactericidal activity, good stability, do not bring phosphorus to pollute environment again simultaneously.The javelle water of the present invention can be directly used for clinic and skin degerming, and 37 DEG C, 75RH when store 3 months after available chlorine content rate of descent little Yu 10%, it was shown that its shelf-life can reach more than 2 years.And its pH value is about 7, it is ensured that have higher bactericidal activity it is also possible to avoid the corrosivity that pH higher band is come.
The combination of the water-soluble grease in composition of raw materials of the present invention and polyvinylpyrrolidone uses, effectively to hypochlorous oxidisability with Bleachability serve slow release;This is mainly due to the addition of water-soluble grease, polyvinylpyrrolidone and other surfactants, create micelle and slow releasing function in the solution, hypochlorous acid can be alleviated to the corrosivity of skin and injury, thus allowing the disinfectant solution of without phosphorus sodium hypochlorite of the present invention can be applied to clinic and skin degerming.
The preparation method that second purpose of the present invention there is provided above-mentioned without phosphorus javelle water, comprises the following steps:
Step one: being sequentially added in reactor by described sodium hypochlorite, described sodium chloride, described sulfamic acid sodium, described polyvinylpyrrolidone, described water-soluble grease, described hydrochloric acid with described water stirring and dissolving becomes solution;
Step 2: processed by exchange column by described solution, can obtain described without phosphorus javelle water.
It is preferred that the filler of described exchange column includes the composition of following percentage by weight:
Zeolite 15~35wt%;
Chitin 10~25wt%;
Aminopolystyrene 5~10wt%;
Polrvinyl chloride 5~30wt%.
Having the beneficial effects that of above-mentioned preparation method: on the one hand, the liquor natrii hypochloritis pH prepared by the method is about 7, it is ensured that it has higher bactericidal activity, it is to avoid the corrosivity that higher pH brings;On the other hand, the method adopts exchange column processing mode, the impurity heavy metal ion in solution can be scavenged into below ppm rank, and very big limit reduces sodium hypochlorite unstable factor;Meanwhile, there is chlorination between sulfamic acid sodium and sodium hypochlorite, it is suppressed that the decomposition of sodium hypochlorite;This solution by 37 DEG C, 75RH when accelerated test, effective chlorine loss rate < 10%, it was shown that its shelf-life is more than 2 years;It addition, the combination of water-soluble grease and polyvinylpyrrolidone uses, effectively to hypochlorous oxidisability with Bleachability serve slow release.Thus allowing it be applied to clinic and skin degerming becomes possible to.In addition, the method adopts raw material and auxiliary agent are all phosphorous, it is to avoid the severe contamination that environment is in use brought by javelle water.
The 3rd purpose of the present invention there is provided the application at skin degerming and clinicing aspect of this without phosphorus javelle water.Due to its long shelf-life, and not there is corrosivity substantially, be suitably applied skin degerming and clinicing aspect.
