Abstract
A composite disinfectant contains 2,2-dibromo-tricyano propanamide, cyanoethanamide and disintegrant proportionally. Its advantages are high solubility and dissolving speed in water, broad spectrum, high effect, safety and stability, and low poison.
Description
Technical field
The present invention relates to a kind of water-soluble Halogen disinfectant.
Background technology
2,2-two bromo-, 3 cyanogen (cyanogen can be translated into nitrile again) basic propionamides (DBNPA), English name: 2,2-Dibromo-3-Nitrilopropion Amide, structural formula:
Molecular weight: 242, outward appearance is: white crystalline powder, effective content 〉=98%, fusing point (MP): 122 ℃-125 ℃, pH value is 4.0～6.5, is mainly used in water treatment, paper making pulp and medicine intermediate, 2,2-two bromo-3 cyano group propionamides are dissolved in the organic solvent, can discharge effective bromine of activation with alleviating, the performance bactericidal action, can be used as bromine release type disinfectant, effectively the bromine content height has no irritating odor good stability, bactericidal action is strong, not many-sided advantage such as chafe and mucous membrane.Because it does not dissolve in water substantially, can not bring into play its bactericidal action, so be not used as the disinfectant extensive use.
Summary of the invention
Existing 2 in order to overcome, 2-two bromo-3 cyano group propionamides are insoluble in the deficiency of water, the invention provides a kind ofly to contain 2 for this reason, the composition of 2-two bromo-3 cyano group propionamide disinfectants, said composition is soluble in water, makes 2, and 2-two bromo-3 cyano group propionamides can extensively use as disinfectant.
The present invention for the technical scheme that solves its technical problem and adopt is: a kind ofly contain 2, and 2-two bromo-3 cyano group propionamide antiseptic compositions,
Mainly comprise following component
Constituent content (WT%)
2,2-two bromo-3 cyano group propionamide 23-70
Cyanoacetamide 20-70
Disintegrant 5-15.
Further technical scheme of the present invention is:
The composition that mainly comprises following component
Constituent content (WT%)
2,2-two bromo-3 cyano group propionamide 23-70
Cyanoacetamide 20-67
Disintegrant 5-15
Sodium sulphate 5-15.
Disintegrant is made up of sodium bicarbonate, citric acid, sodium carboxymethylcellulose.
Contain account for composition weight than 1% polyvidone, account for composition weight than 1% lauryl sodium sulfate with account for composition weight than 1% dolomol.
Contain and account for composition weight than 1% Sodium Benzoate.
Contain 2, the composition of 2-two bromo-3 cyano group propionamide disinfectants is powder.
Contain 2, the composition of 2-two bromo-3 cyano group propionamide disinfectants is tablet.
The beneficial effects of the utility model are: single 2,2-two bromo-, 3 cyano group propionamides solvability in water is very little, and dissolution time is longer, therefore uses as disinfectant to be very limited.Provided by the inventionly contain 2, the disinfectant of 2-two bromo-3 cyano group propionamides, its solvability in water improves greatly, and dissolution velocity is fast, therefore the present invention has solved 2 first, the problems of dissolution of 2-two bromo-, 3 cyano group propionamides in water makes 2, and 2-two bromo-3 cyano group propionamides can utilize on industry as disinfectant;
The present invention contains 2, and disinfectant, its Disinfection Effect of 2-two bromo-3 cyano group propionamides is better than disinfectant commonly used in the market greatly.Containing iodine disinfectant is a class middle effect disinfectants, and its bactericidal effect can't be with 2, and 2-two bromo-3 cyano group propionamides are compared.Chlorine-containing disinfectant is a high effect disinfectants, but bactericidal effect is also than 2, and 2-two bromo-3 cyano group propionamides are poor.Detect through relevant department, the effective content of halogen of product that contains this invention is 50%.Deposit after 14 days effectively that the halogen rate of descent is 3.06% for 54 ℃, stability meets the requirement of Ministry of Public Health's " disinfection technology standard " third edition first fascicle, and the term of validity is 1 year.Every liter of pH value that contains 300 milligrams of thimerosals of effective halogen is 3.06.Under 20 ℃ ± 2 ℃ experimental temperatures, the thimerosal effect 5 minutes that contains effective halogen 100mg/L is 99.97% to staphylococcus aureus and colibacillary killing rate.Organic matter, temperature and pH value are all not obvious to the bactericidal effect influence that this product contains effective halogen 2mg/L thimerosal.Three tests all reach the required lowest dose level of 0cfu/100ml for containing effective halogen 1mg/L effect 3 minutes to colibacillary Disinfection Effect.It is 1.2mg/L that the adding swimming-pool water makes its effective halogen final concentration, and sample detecting result shows sterilization back total number of bacteria＜10cfu/ml, Escherichia coli＜3cfu.The thimerosal effect 7 minutes that contains effective halogen 15mg/L reaches 0cfu/100ml to coliform Disinfection Effect in the natural water-like.The thimerosal effect that contains effective halogen 300mg/L was 95.83% to natural bacteria killing rate on the wooden painted surface in 3 minutes;
Toxicology detects conclusion: 5 times of concentration are used the liquid acute oral toxicity tests: with 5 times of sample application concentration as being tried thing, its male and female chmice acute per os LD
50Be worth all greater than 5000mg/kg b.wt the nontoxic level in true border.Therefore the present invention is 2, and 2-two bromo-3 cyano group propionamides reveal wide spectrum, efficient, safety, low toxicity, characteristics such as stable as the disinfectant application table, are a kind of comparatively desirable disinfectants of novelty.
Embodiment
Embodiment:
A kind ofly contain 2, the disinfectant of 2-two bromo-3 cyano group propionamides comprises 2 of following component, 2-two bromo-3 cyano group propionamide compositions
Constituent content (WT%)
2,2-two bromo-3 cyano group propionamide 23-70
Cyanoacetamide 20-67
Disintegrant 5-15
Sodium sulphate 5-15.
Disintegrant is made up of sodium bicarbonate, citric acid, sodium carboxymethylcellulose;
2, also contain an amount of polyvidone, lauryl sodium sulfate and dolomol, Sodium Benzoate in the 2-two bromo-3 cyano group propionamide compositions, the described composition that respectively adds generally respectively accounts for 1% of composition.
Disintegrant can help the abundant disintegration of tablet; Sodium sulphate plays the filler effect; Polyvidone is a main bonding and synergistic effect in tablet; Lauryl sodium sulfate is a surfactant, can help abundant sterilization; Dolomol makes tablet appearance smooth, glossy.
Contain 2, the disinfectant of 2-two bromo-3 cyano group propionamides can pass through conventional process such as physical mixed, pulverizing, screening 2, and it is Powdered that 2-two bromo-3 cyano group propionamide compositions are made, and becomes disinfectant powder; Can certainly make tablet.Above-mentioned composition makes powder and tablet all is a conventional means, is not repeating here.
Disinfection principle of the present invention is: cyanoacetamide and 2,2-two bromo-3 cyano group propionamide structural formulas are identical, can produce common-ion effect, cyanoacetamide can replace 2, and a bromide ion of 2-two bromo-3 cyano group propionamides is so make 2,2-two bromo-3 cyano group propionamides become the monobromo cyanoacetamide, and the monobromo cyanoacetamide is fully can be water-soluble, and the monobromo cyanoacetamide can discharge effective bromine in water, thereby reaches bactericidal effect.
2,2-two bromo-3 cyano group propionamide disinfectant tablets are high-efficiency broad spectrum disinfectants of new class, can be widely used in environment and surface disinfection; Vegetables, fruit sterilization; The medical apparatus sterilization; Waste water treatment; Aquatic products, herding sterilization; Swimming sterilizing; Water closet and urinal sterilization; The cycle water sterilization; The sterilization of all many-sides such as agricultural and daily-use chemical industry.Along with the raising of living standards of the people, to the reinforcement of sterilization, environmental consciousness, 2,2-two bromo-3 cyano group propionamide disinfectant tablets will progressively replace chlorine-containing disinfectant and be admitted by increasing people, have the prospect of using widely.
