(Industrial Application Field) The present invention relates to a chlorine dioxide agent that can easily generate chlorine dioxide during use and is stable during storage. (Prior Art and Problems) Chlorine dioxide, which has strong oxidizing power, is used in a wide range of fields such as bromine and bleaching, but since it is an inherently unstable substance, it must be generated at the site of use. Conventionally, as a method for obtaining chlorine dioxide, various solid stabilized chlorine dioxide agents and chlorine dioxide generating agents have been developed in the case of small amounts of chlorine dioxide such as bromine, antiseptic, antifungal, and sterilizing agents. For example, compositions in which an aqueous solution containing chlorine dioxide, such as an aqueous solution of sodium chlorite or stabilized chlorine dioxide, is adsorbed on a basic adsorbent such as calcium silicate (see Japanese Patent Publication No. 32079/1983) are known. This product has a chlorine dioxide-containing aqueous solution adsorbed only on the very surface of the basic adsorbent, so when this product is mixed with a solid acid during use, a large amount of chlorine dioxide-containing salt and solid acid react in a short time. generates high concentrations of chlorine dioxide. Therefore, it is not suitable for long-term continuous generation at low concentrations. Also, a composition in which chlorite or stabilized chlorine dioxide is mixed with an alkaline solid substance and an alkaline oxidizing agent (see Japanese Patent Application Laid-Open No. 161904/1983) is known, but this composition is insufficiently stable. And,
Chlorine dioxide continues to be generated during product distribution and storage, i.e., when not in use, just as when it is in use, so not only is its usage efficiency inferior, but the concentration conditions are determined in advance depending on the type of oxidizing agent used during manufacturing. Since it is fixed, it is difficult to adjust it during use. (Object of the Invention) In view of the above points, the present inventors conducted extensive research with the aim of obtaining a chlorine dioxide agent that can arbitrarily adjust the concentration and duration of generation of chlorine dioxide and is stable during storage. As a result, the present invention was completed based on the discovery that the above objects can be fully achieved using a specific carrier carrying an alkaline agent and an aqueous solution containing chlorine dioxide. (Structure of the Invention) The present invention is characterized in that sepiolite supports an alkaline agent consisting of one or more of hydroxides of lithium, sodium, and potassium, and stabilized chlorine dioxide and/or alkali chlorite salt. It is a stabilized chlorine dioxide agent. Sepiolite used in the present invention is a natural mineral of magnesium silicate salt, and its chemical structure is (OH 2 ) 4 (OH) 4 (OH 2 ) 4 Mg 8 Si 12 O 30 ·6-8H 2 O
It has a fibrous crystal structure with many grooves on its surface and many clearances in the form of a cylindrical tunnel structure, making it a substance with a very large surface area. Due to this structure, it has adsorption properties, plasticity, thixotropy, and dry solidification properties. In the present invention, a pulverized and refined sepiolite raw ore, or a granular, powdery, or fibrous material obtained by further heating and burning at 100 to 800° C. can be used depending on the purpose. Furthermore, sepiolite has an extremely high water absorption and retention capacity, and even when it absorbs water equivalent to its own weight, it can appear dry on the surface. The stabilized chlorine dioxide water used in the present invention is known. That is, it can be produced by absorbing chlorine dioxide gas that does not contain chlorine into an aqueous solution of an alkaline peroxygen compound such as sodium percarbonate or sodium peroxide. In the present invention, it is also possible to use an aqueous solution of alkali chlorite salt in place of the stabilized chlorine dioxide solution. As the alkali chlorite salt of the present invention, either an alkali metal salt or an alkaline earth metal salt of chlorite can be used. Generally, an aqueous solution of sodium chlorite is used, which is inexpensive and easily available. Aqueous solution of the above-mentioned stabilized chlorine dioxide or alkali chlorite salt (hereinafter referred to as chlorine dioxide-containing aqueous solution)
Examples of the alkaline agent to make alkaline include hydroxides of lithium, sodium, and potassium, with sodium hydroxide being more preferably used. The amount of alkali agent used is usually sepiolite 100
A suitable amount is 1 part by weight or more, preferably 2 to 10 parts by weight, in solid terms. If it is less than 1 part by weight, the supported chlorine dioxide may be slightly decomposed even at room temperature. On the other hand, if it exceeds 10 parts by weight, stability is improved, but chlorine dioxide is less likely to be generated and the concentration of generated chlorine dioxide is lowered, which is not preferable. The stabilized chlorine dioxide agent of the present invention can be obtained by adding and mixing a mixed solution of an aqueous solution containing chlorine dioxide and an alkali agent to sufficiently dried sepiolite, or by adding and mixing an aqueous solution containing chlorine dioxide to sepiolite after adding and mixing the alkali agent to sepiolite. can get. In this case, the amount of chlorine dioxide supported depends on the water absorption capacity of sepiolite, so to increase the amount supported, dry the supported material, e.g. vacuum drying at 40 to 60°C, and then repeat the supporting process, or use the above-mentioned alkaline agent. The operations of adding, mixing, drying, supporting an aqueous solution containing chlorine dioxide, and drying are repeated. In this way sepiolite
Chlorine dioxide is effective at 1 part by weight or more per 100 parts by weight, but it is also possible to stably support 30 parts by weight or more. In the product of the present invention, chlorine dioxide is included in the clearances of the numerous cylindrical tunnel structures of sepiolite, and is much more stable than when supported on other naturally occurring magnesium silicate minerals. The product of the present invention is sufficiently stable both in the undried state and in the dry state. Therefore, it is not necessarily necessary to dry it. The product of the present invention can be made into various molded products such as powder, granules, tablets, or briquettes depending on the purpose. The stabilized chlorine dioxide agent of the present invention can be used in various ways depending on the application and conditions such as the desired chlorine dioxide gas concentration. For example, to deodorize food waste placed in a container, it is sufficient to simply spray the product of the present invention as it is and seal the container. In this case, the malodorous component is adsorbed by sepiolite, and this component reacts with chlorine dioxide in sepiolite to eliminate the odor. When a high concentration of chlorine dioxide is desired, an acid in the form of an aqueous solution may be appropriately added and mixed with the stabilized chlorine dioxide agent of the present invention. Since the sepiolite in the product of the present invention has properties that are sufficiently resistant to acids and is difficult to gel, the active ingredients of the product of the present invention can be used efficiently without waste. In addition, methods such as hot air ventilation and addition and mixing of a solid acid or oxidizing agent may be used depending on desired conditions such as generation concentration and duration. As described above, the product of the present invention is extremely stable in both dry and undried states if it is stored tightly closed when not in use, avoids natural decomposition, and can withstand long-term storage. On the other hand, during use, the desired chlorine dioxide generation concentration can be easily and variably selected from a high concentration to a low concentration, and the concentration time conditions can be set or changed during use. Further, this will be specifically explained using examples. % in example
is based on weight. Example 1 100 parts by weight of sepiolite having the composition shown in Table 1 dried at 120°C for 3 hours (Miraclay G manufactured by Ohmi Mining Co., Ltd.)
-16/48" particle size 16-48 mesh), add and mix a mixture of 50% sodium hydroxide aqueous solution and 25% sodium chlorite aqueous solution (PH11.5) in the amounts listed in Table 2, and mix the amounts shown in Table 2. A stabilized chlorine dioxide agent was obtained.
The chlorine dioxide content of these materials was 5% in all cases. No drying was performed. 40 g of this stabilized chlorine dioxide agent was placed in a 100 ml polyethylene container, sealed, and cured for two months at the temperatures shown in Table 3, followed by a decomposition test. Table 3 shows the results. The decomposition rate was calculated from the ratio of the remaining amount of chlorine dioxide in the stabilized chlorine dioxide agent in the container to the initial amount. Comparative Example 1 Example 1 except that formulation E described in Table 2 was used.
Table 3 also shows the results of tests conducted in the same manner as above. Table 1 (%) SiO 2 57.0 A 2 O 3 1.0 MgO 23.0 Fe 2 O 3 0.5 CaO 2.0 Ma 2 O 0.2 K 2 O 0.3 Loss on ignition 14.5
