Abstract
A disclosed production formula for a neutral chlorine dioxide powder (unitary package) contains: (1) 10-50% of a main agent (sodium chlorite); (2) 1-20% of an activator (citric acid, tartrate, boric acid and sodium bisulfate); (3) 2-30% of an activation auxiliary agent (sodium dichloroisocyanurate and sodium trichloroisocyanurate); and (4) 5-50% of an additive (sodium sulfate and sodium chloride); and (5) 10-40% of an assistant agent (anhydrous magnesium sulfate). The chlorine dioxide powder with different contents and different packaged forms can be prepared by physical mixing. When the chlorine dioxide powder is directly dissolved or diluted into a solution with a chlorine dioxide concentration of 200-250 mg/L, the pH value of the solution is closes to 7, and the solution is neutral. The technology of the invention does not belong to the prior art, and has great breakthrough and improvement on the prior art. The technology helps to creatively make up the disadvantage that conventional solutions with a chlorine dioxide concentration of 200-250 mg/L have a pH value of 1-3 and belong to acidic solutions or relatively strong acidic solutions, and helps to enable the chlorine dioxide solution to be neutral, and thus the chlorine dioxide solution possesses relatively wide application value.
Description
Technical field
chlorine dioxide (disinfectant, bactericide).
Molecular formula: ClO
2.
Relative molecular mass: 67.45.
Chlorine dioxide is generally acknowledged both at home and abroad as efficient, broad-spectrum, quick, nontoxic disinfection sanitizer.Due to its complete non-carcinogenesis, toxicity, abnormal property, by the World Health Organization (WHO), classified as AI level security disinfectant.It can kill various bacterial propagules, Candida albicans, Escherichia coli and Bacillus subtilis gemma fast, and energy deactivation hepatitis viruse, kills the algae spore.Human body skin germ virus is had well kill, therapeutic action.At present, chlorine dioxide can be used as the production and sales of the products such as disinfectant, antistaling agent, algicide, water treatment agent, can also be as development, the production and sales of agriculture chemicals fungicide, medicine (external application) medicine.
Background technology
the prior art situation:at present, the chlorine dioxide of domestic production mainly divides two large classes: the one, and solid, the 2nd, liquid.Solid divides again two-component packaging and monobasic packing.No matter be liquid or solid (two-component packaging or monobasic packing), the raw material played a major role in formula is sodium chlorite, citric acid (niter cake or hydrochloric acid) etc.Existing chlorine dioxide powder (monobasic packing), its effective content is generally 6-10%.PH value when it is mixed with 200-250mg/L chlorine dioxide concentration solution is generally 1-3, belongs to acid or than highly acid.
" * * board disinfection agent of chlorine dioxide " that enterprise produces, three batches of samples are respectively 1.19,1.20 and 1.22 containing the pH value of the chlorine dioxide 250mg/L aqueous solution after testing.［ survey report numbering: No. (2009) 0264, river disease (disappearing) inspection ］.
" * * board disinfection agent of chlorine dioxide " that enterprise produces, chlorine dioxide disinfection liquid stoste mean ph value 2.37 after testing.［ numbering is accepted in check: 2013XD-X0004 ］.
Chinese patent application publication No. CN 101946798A discloses a kind of two yuan of neutral disinfection agent of chlorine dioxide and preparation method thereof, but in claims, specification and embodiment, and undeclared or have examining report to prove its pH value is how many, can not conclude acid or neutral.
Yunnan Province research institute of scientific-technical information goes out the novelty assessment report ［ report number: (2013) 53b200001607 ］ of certificate, does not also find any patented product that the pH value is the neutral chlorine dioxide powder of 6-7.
the prior art defect:acid ClO 2 solution exists certain defect.
Choke highly seasoned.Under acid or more highly acid condition, it is fast that chlorine dioxide discharges, and also just volatilization is fast, and the flavor of choking is also heavy, and stability is just poor comparatively speaking.Especially the flavor of choking is too heavy, can have influence on the healthy of workman.
Corrosivity is larger.Chlorine dioxide itself belongs to a kind of strong oxidizer, has certain corrosivity, adds to belong to acid or, than highly acid, corrosivity is just larger.As Shandong Center for Disease Control & Prevention, " * * board disinfection agent of chlorine dioxide " being done to carbon steel, copper and its result of aluminum metal corrosion test is severe corrosion ［ test specimen is accepted numbering: 20021165 ］.
The limitation of the scope of application.In pharmaceuticals industry, according to related tests, chlorine dioxide has good curative effect effect in the department of stomatology, gynaecology, dept. of dermatology, but because ClO 2 solution becomes acidity or, than highly acid, should not directly touch human body; In the agricultural planting industry, particularly, in the sterilization in tobacco seedling stage, requiring the pH value scope of all sterilization objects is 5-7, if adopt more highly acid ClO 2 solution to carry out soaking disinfection to its tobacco seedling-culturing dish, will change the pH value of seedling-cultivating tray, by neutrality, become acidity.Therefore acid chlorine dioxide should not use in above-mentioned two large fields.
Cause the reason of prior art defect: this is to be determined by traditional theory and activating technology.That is: chlorine dioxide only, under acid or more highly acid condition, could activate into effective ClO 2 solution.
Summary of the invention
goal of the invention:how to change existing ClO 2 solution and become acid or than this deficiency of highly acid or defect, be not simply to regulate the problem of pH value, but how could allow chlorine dioxide powder also can activate into effective ClO 2 solution under neutral condition, the key technology difficult problem that the present invention that Here it is will solve.Solve this key technology difficult problem, just must be the performance of product, on the activation principle, improved on formula for a product and improved, its purpose is exactly to invent a kind of chlorine dioxide powder of neutrality.
the technical barrier solved and method:to achieve these goals, just must solve two problems: the first, the problem of ClO 2 solution pH value; The second, the activation capacity problem of chlorine dioxide powder under neutrallty condition.The method that solves first problem is simple, reduces activator (solid acids) ratio shared in formula and gets final product, and by the pH value, 1-3 becomes 5-7.But it is just difficult to solve Second Problem, because the chlorine dioxide powder of producing by prior art is impossible activate into effective ClO 2 solution under the condition of neutral (or weak acid), or the activation effect extreme difference.For this reason, the present invention has invented a new activating technology (assistant activator) in formula, improved the activity function of chlorine dioxide powder, not only make ClO 2 solution become neutral, but also can allow chlorine dioxide powder activate into effective ClO 2 solution under neutral condition, solved up hill and dale this technical barrier.
the invention formula:host (sodium chlorite) 10-50%; Activator (citric acid, tartaric acid, boric acid, niter cake) 1-20%; Assistant activator (sodium dichloro cyanurate, sodium trichloro-isocyanurate) 2-30%; Additive (sodium sulphate, sodium chloride) 5-50%; Assistant agent (anhydrous magnesium sulfate) 10-40%.In the proportion of above-mentioned formula regulation, can be by the physical mixed to various formulation raw material different proportions, be combined into the neutral chlorine dioxide powder of different content, Different Package form, when it directly dissolves or is diluted to 200-250mg/L concentration solution, pH value scope is 5-7.
Its key reaction form is: ［ NaCLO
2+ NaHSO
4+ C
