Abstract
The present invention relates to a method for producing chlorine dioxide by acidifying sodium chlorite, sodium chlorite is used as a raw material, a solid acidifying agent prepared from oxalic acid dihydrate, tartaric acid or citric acid and aluminum trichloride is used for acidifying the sodium chlorite to produce chlorine dioxide, the solid acidifying agent comprises the components by weight: 1 portion of sodium chlorite, 1 portion of oxalic acid dihydrate and tartaric acid or citric acid and 1 to 9 portions of aluminum trichloride. The chlorine dioxide generated by the method of the present invention can be used for the disinfection of potable water, dinnerware, fruits and other articles.
Description
The invention belongs to a kind of production method of disinfection agent of chlorine dioxide.
Dioxide peroxide is a kind of strong oxidative disinfectant, and its sterilization effect is better than free chlorine.At present, the method that is used to produce disinfection agent of chlorine dioxide is a lot, wherein the method with producing chlorine dioxide by acidifying chlorous sodium is the simplest, general hydrochloric acid or the sulfuric acid acidation Textone of adopting, Textone can produce dioxide peroxide rapidly under strong acid (pH＜0.5), but, because the chemical property instability of dioxide peroxide, need be with using with joining; Use liquid hydrochloric acid or sulfuric acid very dangerous, carry very inconvenient, so limited the application of dioxide peroxide.Also have the solid acid of employing to come the acidifying Textone, but can not promptly come out chlorine dioxide activation, its activation rate has only about 20%.
The objective of the invention is to overcome the deficiency that above-mentioned technology exists, provide a kind of and be easy to carry, easy to use and safe solid acidifier comes the acidifying Textone, can produce the method for capacity dioxide peroxide.
The present invention realizes like this, with the Textone is raw material, use oxalic acid, the solid acidifier that tartrate or citric acid and aluminum chloride are formed comes the acidifying Textone to produce dioxide peroxide, by weight Textone: oxalic acid, tartrate or citric acid: aluminum chloride is 1: 1: 1-9, the plastics bag A that according to the above ratio Textone that takes by weighing packed into packs, with the oxalic acid that takes by weighing, pack among tartrate or citric acid and another plastics bag B that packs into after aluminum chloride mixes, also can be with oxalic acid, tartrate or citric acid and aluminum chloride are respectively charged among plastics bag C and the D and pack.Cut off during use and mix the plastics bag B that oxalic acid, tartrate or citric acid and aluminum chloride are housed, or cut off plastics bag C and the D that oxalic acid, tartrate or citric acid and aluminum chloride are housed respectively, add a certain amount of water, with solid mixture dissolving (pH of water is below 0.5), and then the Textone of another bag poured into, mixed dissolution makes the Textone rapid acidification produce dioxide peroxide, and dilution is used then.
The present invention has the following advantages:
1. oxalic acid, tartrate or citric acid and the aluminum chloride of the present invention's use all are solids, and therefore safety easy to use is easy to carry.
2. the solid acidifier of being made up of oxalic acid, tartrate or citric acid and aluminum chloride that uses of the present invention adds a certain amount of water, understands generation strong acid, makes pH below 0.5, can improve the activation rate of dioxide peroxide so rapidly, can reach more than 90%.
3. the solid acidifier of being made up of oxalic acid, tartrate or citric acid and aluminum chloride that uses of the present invention does not add water and directly mixes with Textone, can slowly discharge dioxide peroxide, and storage and the fruit and vegetable transported are played the fungus-proof antisepsis effect.
The dioxide peroxide that the present invention produces can be used for sterilizations such as tap water, tableware, fruit and other article.
