の安定性を改善した、保存安定性の優れた塩素化イソシ
アヌル酸組成物に関する。DETAILED DESCRIPTION OF THE INVENTION (Industrial application field) The present invention has improved the stability of a chlorinated isocyanuric acid composition used for sterilization and bleaching washing by hydrolyzing in water and releasing active chlorine. The present invention relates to a chlorinated isocyanuric acid composition having excellent storage stability.

びジクロロイソシアヌル酸カリウムなどが挙げられる。(Conventional technology and problems) Conventionally, chlorinated isocyanuric acid has been used in a wide range as a bactericidal / disinfectant for pool water, sewage, industrial water, cooling water, etc., as an algicide or for bleaching and washing fibers. Examples of the chlorinated isocyanuric acid include trichloroisocyanuric acid, dichloroisocyanuric acid, sodium dichloroisocyanurate, dihydrate of sodium dichloroisocyanurate, and potassium dichloroisocyanurate.

It is provided in many types of dosage forms such as granules, spheres and tablets, and to control dissolution in water,
Formulations in which not only the shape but also the composition are devised have been studied.

化窒素ガスを発生することが多い。特に、トリクロロイ
ソシアヌル酸の場合が顕著である。However, chlorinated isocyanuric acid is liable to generate chlorine gas or nitrogen chloride gas during storage or use, particularly when wet, and tends to cause a decrease in effective components and deterioration of packaging materials. When an alkaline compound is blended with chlorinated isocyanuric acid, it is stable in a dry state,
In a wet state, decomposition is extremely severe, and the generation of chlorine gas and nitrogen chloride gas is accelerated. Further, since chlorinated isocyanuric acid is a strong oxidizing agent, when it is mixed with another chemical substance, chlorinated isocyanuric acid itself is often decomposed to generate chlorine gas or nitrogen chloride gas. In particular, the case of trichloroisocyanuric acid is remarkable.

ることは困難である。Thus, it is not easy to determine the formulation of a blend with chlorinated isocyanuric acid, as mixing with water or various compounds promotes autolysis. Accordingly, considerable research has been conducted on the properties of the chlorinated isocyanuric acid described above. For example, in order to suppress the generation of decomposition gas from the solid chlorine agent, it is effective to reduce the moisture content in the product, or it is effective to completely shut off the outside moisture during storage. There are some proposals other than the above, but none of them are satisfactory. For example, it is difficult to manufacture a completely anhydrous product because it is almost impossible in industrial production.Also, even if metal is used as a packaging material that can completely block the outside air, it is gradually sealed during long-term storage. The accumulation of the cracked gas causes the deformation or breakage of the vessel due to corrosion of the vessel wall or pressure increase. There is also a proposal to coat the surface of the solid chlorine agent with a film of an inert substance, for example, paraffin wax or polyvinyl alcohol, but the effect is not sufficient as above, and when used for pool sterilization, an oil component is provided in the pool water. I don't like it. Further, as another proposal, there is a method of storing a solid chlorine agent in a paperboard container having an inner surface coated with an alkali metal silicate as described in US Pat. No. 3,061,549. However, in the case where the paper board is coated with an alkali metal silicate, the container deteriorates in a short period of time, not only cannot withstand long-term storage, but also cannot sufficiently suppress the decomposition of the solid chlorine agent. In addition, it is difficult to store the solid chlorine agent unchanged for a long period of time.

For example, in U.S. Pat.
A method is proposed in which a compound such as sodium phosphate, ferrous oxide, magnesium oxide, zeolite, melamine, ammeline, etc. is put in a porous bag with air permeability, and a solid chlorine agent is enclosed in a storage container to stably store the solution. However, when the chlorinated isocyanuric acid is taken out of the container, there are drawbacks such as the porous bag closing the opening of the storage container, and the effectiveness of the bag may be damaged.

0号と同じ問題がある。Japanese Patent Application Laid-Open No. 58-128382 proposes a method of suppressing the generation of chlorine gas by using a specific synthetic zeolite (aluminosilicate as a main component), but a remarkable effect is not necessarily obtained. The present inventors have already applied for a stabilizing agent comprising an allophane-based compound and activated carbon for this storage stability as JP-A-59-266737. This product has good storage stability, but it has activated carbon, so if it is mixed with chlorinated isocyanuric acid, the product will be colored black, the product image will not be good, and the stabilizer must be used in a porous bag. No. U.S. Pat.
There is the same problem as No. 0.

When they were blended together, they found that they were stable even in a wet state, and completed the present invention.
