Description
Technical Field
The invention relates to a sterilizing disinfectant, in particular to a stable chlorine dioxide effervescent agent and a preparation method thereof.
Background
Chlorine dioxide is a high-efficiency, nontoxic, rapid and spectral disinfectant, and is a fourth-generation safe and nontoxic green disinfectant recognized internationally. Can kill bacteria, fungi, viruses, spores and other microorganisms, has a disinfection effect superior to that of common hypochlorite, chlorine, glutaraldehyde and other disinfectants, is 8 times of that of chlorine, and does not produce chloralkane and other carcinogenic substances.
The early chlorine dioxide disinfectant mostly leads chlorine dioxide gas into inert solution to form 2-5% solution, but the content is low, the chlorine dioxide can be released only by adding an activating agent when the chlorine dioxide disinfectant is used, the content of the chlorine dioxide can be reduced after the chlorine dioxide disinfectant is stored for a long time, the sterilization and disinfection effect is influenced, and the transportation and storage cost is high. Therefore, the chlorine dioxide solid preparation is popular in the market, and compared with a liquid chlorine dioxide solution, the chlorine dioxide solid preparation has the advantages of simple use and operation, high effective content, convenient transportation and use and the like.
solid chlorine dioxide preparations used in the market at present are all prepared by fully mixing chlorite serving as a chlorine dioxide source, organic acid or inorganic strong acid weak base salt serving as an activating agent, sodium carbonate serving as an effervescent agent and magnesium sulfate or calcium chloride serving as a drying and isolating agent to prepare powder or tablets for use. However, chlorite is very easy to decompose under the moist and weak acid conditions, so that the effective content is easy to gradually reduce in the production, storage and transportation processes, which affects the sterilization and disinfection effect, and more importantly, the concentration of chlorine dioxide gas generated by chlorite decomposition reaches a certain limit, which can cause potential safety hazards such as explosion hazard.
Chinese patent CN101695305A discloses a unitary packaged chlorine dioxide powder, which mainly comprises sodium chlorite, sulfamic acid, sodium bisulfate, magnesium sulfate and sodium dichloroisocyanurate, and the content of the product is 20%. Chinese patent CN101411334 discloses a method for preparing chlorine dioxide disinfectant powder by using sodium chlorite, sodium bisulfate, anhydrous magnesium sulfate and anhydrous sodium carbonate polyethylene glycol as raw materials. However, when the formulation is used and dissolved, when a certain amount of the preparation is added into water, an explosion sound is generated, which is a precursor of chlorine dioxide explosion and is a potential safety hazard, so how to solve the safety problems that the solid preparation of chlorine dioxide is easy to decompose and explode and the like, a stable solid effervescent agent of chlorine dioxide is urgently needed to be found, and the stable solid effervescent agent of chlorine dioxide has important significance for eliminating the potential safety hazard, improving the production and storage stability of products and ensuring the disinfection effect of chlorine dioxide.

the stable chlorine dioxide effervescent agent has the effective content of chlorine dioxide of 8-12%.
The invention has the following beneficial effects:
the stable chlorine dioxide effervescent agent of the invention generates chlorine dioxide by the oxidation-reduction reaction of A, B raw materials under the existence of catalyst in aqueous solution of oxidant and reducer, therefore, under the dry state, no reaction occurs, the product is safe and stable when not used, and the danger of explosion during the production, storage and transportation of the product is eliminated. The reaction equation is:
2NaClO3+NaHSO3+NaHSO4＝2ClO2+2Na2SO4+H2O
Sodium chlorate is a strong oxidant, sodium bisulfite is a reducing agent, the sodium chlorate and the sodium bisulfite generate oxidation-reduction reaction under the acidic condition in aqueous solution to generate chlorine dioxide, copper sulfate enters the aqueous solution to form copper ions, the copper ions are used as catalysts of the oxidation-reduction reaction, the reaction can be accelerated, and the chlorine dioxide is rapidly generated to play a role in quickly sterilizing and disinfecting. Meanwhile, the copper sulfate also has the sterilization and disinfection effects and has the synergistic sterilization and disinfection effects with the chlorine dioxide. The addition of sodium carbonate in water solution produces carbon dioxide gas under acidic condition to produce effervescence and to make the powder or tablet disintegrate fast and speed up the reaction.
