【０００１】
【産業上の利用分野】
本発明は安全性に優れた遅溶解性塩素化イソシアヌル酸成形物に関し、詳しくは、該成形物を水中に浸漬した際、水中で膨張、崩壊する事無しに溶解する他、油や洗剤等の物質と接触しても安定性に優れた塩素化イソシアヌル酸成形物である。該成形物は、家庭用台所の流し台の滑り取り等安全性が要求される場所における殺菌消毒に有効に使用される。
【０００２】
【従来の技術】
従来は速効性と持続性を備えた錠剤として、ジクロルイソシアヌル酸アルカリ金属塩に２〜５０％の固体状の酸性物質を配合した錠剤が使用されていた（特公平１−５３８４４号公報等参照）。また、同様の目的の塩素化イソシアヌル酸にジクロルイソシアヌル酸塩の水和物を配合した錠剤が、特開平５−４３４０７号公報に開示されている。
【０００３】
【発明が解決しようとする課題】
しかしながら、前記の様な混合錠剤では溶解速度が速く、長期に持続を目的にした場合は好ましくない。さらに、家庭用台所の流し台等に使用する場合には油や洗剤等の物質等と接触する可能性があるが、前記の様な混合錠剤では安全性（反応性）の面で問題があった。従って、家庭用台所の流し台等に使用する場合には安全性に優れ、しかも長期にわたって安定して一定量づつ溶解する殺菌消毒剤が渇望されている。
【０００４】
本発明は、このような事情から見てなされたもので、上述の諸問題点を改善した安全性に優れた遅溶解性塩素化イソシアヌル酸成形物を提供することを目的とする。
【０００５】
【課題を解決するための手段】
本発明者らは前記の問題点を解決するため、鋭意検討を重ねた結果、塩素化イソシアヌル酸及び／又はそのアルカリ金属塩の水和物に常温で固体状の有機酸を特定の割合で配合して得られる成形物が、長期にわたって安定して一定量づつ溶解し、しかも安全性に優れていることを見いだし、本発明の完成に至った。
【０００６】
本発明は、塩素化イソシアヌル酸及び／又はそのアルカリ金属塩の水和物と、有機酸を含有する加圧成形体であり、その有機酸の含有量が成形体の５１〜９９重量％であるを特徴とする、安全性に優れた遅溶性塩素化イソシアヌル酸成型物である。
以下、本発明を詳細に説明する。
【０００７】
本発明に用いる塩素化イソシアヌル酸は、トリクロルイソシアヌル酸、ジクロルイソシアヌル酸であり、これらは単独又は混合して使用される。
【０００８】
本発明の塩素化イソシアヌル酸のアルカリ金属塩の水和物は、ジクロルイソシアヌル酸ナトリウム一水和物、ジクロルイソシアヌル酸ナトリウム二水和物及びジクロルイソシアヌル酸カリウム一水和物等から選ばれた少なくとも一種が用いられる。これらは、一種又は二種以上の混合物として使用される。
【０００９】
本発明において、前記原料の塩素化イソシアヌル酸、塩素化イソシアヌル酸のアルカリ金属塩の水和物および有機酸は、粉末状、顆粒状等の物が用いられる。
【００１０】
本発明において、使用される有機酸はフマル酸、安息香酸、アジピン酸およびコハク酸よりなる群から選ばれた少なくとも一種であり、二種以上の混合物としても使用される。
【００１１】
本発明に使用する有機酸は、塩素化イソシアヌル酸及び塩素化イソシアヌル酸のアルカリ金属塩の水和物と比較し水に対する溶解度が小さい事から、有機酸の混合割合を５１〜９９重量％として成形した場合に遅溶解性の物が得られる。成形物の水溶解性を低くする目的に対しては塩素化イソシアヌル酸を使用することがより好ましい。
【００１２】
本発明に使用する有機酸が、一般に家庭等で使用している油や洗剤等の物質に対し不活性であることから、有機酸の混合割合を５１〜９９重量％として成形した場合に安定性に優れる物が得られる。成形物の安全性を高める目的に対しては塩素化イソシアヌル酸のアルカリ金属塩の水和物を使用することがより好ましい。
【００１３】
有機酸の混合割合は５１〜９９重量％であるが、５１％未満の場合溶解速度が速すぎるばかりでなく、安全性の問題が生じる。一方、配合割合が９９％を越えると、殺菌消毒に十分な残留塩素量を満たすことが出来ない。
本発明の成形体中の有機酸の配合割合は５１〜９９重量％であるが、溶解速度、油等と接触した場合の安全性を考慮して、使用する塩素化イソシアヌル酸およびその金属塩の水和物によって有機酸はその範囲内で任意に選択することができる。特に好ましい例は以下の通りである。
塩素化イソシアヌル酸と有機酸を使用する場合、有機酸は、成形品重量の７０〜８５重量％用いるのが特に好ましく、塩素化イソシアヌル酸のアルカリ金属塩の水和物と有機酸を使用する場合、有機酸は成形品重量の６５〜８０重量％が特に好ましい。また、塩素化イソシアヌル酸とそのアルカリ金属塩の水和物および有機酸を使用する場合、有機酸は成形品重量の５１〜７０重量％が特に好ましい。
【００１４】
また、加圧成形をする際には、必要に応じてこれにステアリン酸カルシウム、ステアリン酸マグネシウム、ステアリン酸ナトリウム、安息香酸ナトリウム、オルトほう酸等の滑沢剤を、０．１〜５重量部配合することにより、加圧成形を容易にすることができる。
【００１５】
さらに、目的に応じて、亜硝酸塩、珪酸塩、ポリリン酸塩等の無機系腐食抑制剤、カルボン酸、金属石鹸、スルホン酸、アミン、エステル、リン酸エステル等の有機系腐食抑制剤、ＥＤＴＡ、グルコン酸、ニトリロトリ酢酸等のキレート化合物等の腐食抑制剤を必要量配合し、金属の腐食を抑制することが出来る。
【００１６】

The present invention relates to a slowly soluble chlorinated isocyanuric acid molded article excellent in safety, and more specifically, when the molded article is immersed in water, it dissolves in water without swelling or disintegrating, and oil, detergent, etc. It is a chlorinated isocyanuric acid molded product that is excellent in stability even when contacted with a substance. The molded article is effectively used for sterilization and disinfection in places where safety is required, such as sliding a kitchen kitchen sink.
[0002]
[Prior art]
Conventionally, as a tablet having rapid action and durability, a tablet in which 2 to 50% of a solid acidic substance is blended with an alkali metal salt of dichloroisocyanuric acid has been used (see Japanese Patent Publication No. 1-53844). ). JP-A-5-43407 discloses a tablet comprising chlorinated isocyanuric acid for the same purpose and a hydrate of dichloroisocyanurate.
[0003]
[Problems to be solved by the invention]
However, such a mixed tablet has a high dissolution rate and is not preferred when it is intended for long-term maintenance. Furthermore, there is a possibility of contact with substances such as oil and detergent when used in a kitchen sink of a home kitchen, etc., but such a mixed tablet has a problem in terms of safety (reactivity). . Accordingly, there is a strong demand for a sterilizing and disinfecting agent that is excellent in safety when used in a kitchen sink of a home kitchen, and that dissolves in a fixed amount stably over a long period of time.
[0004]
This invention is made | formed in view of such a situation, and it aims at providing the slow-dissolution chlorinated isocyanuric acid molding excellent in the safety | security which improved the above-mentioned various problems.
[0005]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, the present inventors have conducted intensive studies, and as a result, blended chlorinated isocyanuric acid and / or hydrates of alkali metal salts thereof with a solid organic acid at a specific ratio. It was found that the molded product thus obtained was dissolved in a constant amount stably over a long period of time and was excellent in safety, and the present invention was completed.
[0006]
The present invention is a pressure-molded body containing a hydrated chlorinated isocyanuric acid and / or alkali metal salt thereof and an organic acid, and the content of the organic acid is 51 to 99% by weight of the molded body. Is a slow-melting chlorinated isocyanuric acid molded product excellent in safety.
Hereinafter, the present invention will be described in detail.
[0007]
The chlorinated isocyanuric acid used in the present invention is trichloroisocyanuric acid or dichloroisocyanuric acid, and these are used alone or in combination.
[0008]
The alkali metal salt hydrate of chlorinated isocyanuric acid of the present invention is selected from sodium dichloroisocyanurate monohydrate, sodium dichloroisocyanurate dihydrate, potassium dichloroisocyanurate monohydrate, and the like. At least one kind is used. These are used as one kind or a mixture of two or more kinds.
[0009]
In the present invention, the raw material chlorinated isocyanuric acid, hydrated alkali metal salt of chlorinated isocyanuric acid, and organic acid may be powdery or granular.
[0010]
In the present invention, the organic acid used is at least one selected from the group consisting of fumaric acid, benzoic acid, adipic acid and succinic acid, and is also used as a mixture of two or more.
[0011]
The organic acid used in the present invention has a low solubility in water compared to chlorinated isocyanuric acid and hydrated alkali metal salt of chlorinated isocyanuric acid, so the mixing ratio of organic acid is 51 to 99% by weight. In this case, a slowly soluble substance is obtained. For the purpose of lowering the water solubility of the molded product, it is more preferable to use chlorinated isocyanuric acid.
[0012]
The organic acid used in the present invention is generally inert to substances such as oils and detergents used at home, etc., so stability when molded at a mixing ratio of 51 to 99% by weight of organic acid. Can be obtained. For the purpose of increasing the safety of the molded product, it is more preferable to use a hydrate of an alkali metal salt of chlorinated isocyanuric acid.
[0013]
The mixing ratio of the organic acid is 51 to 99% by weight, but if it is less than 51%, not only the dissolution rate is too high, but also a safety problem arises. On the other hand, if the blending ratio exceeds 99%, the amount of residual chlorine sufficient for sterilization cannot be satisfied.
The blending ratio of the organic acid in the molded body of the present invention is 51 to 99% by weight, but considering the dissolution rate and safety when in contact with oil or the like, the chlorinated isocyanuric acid and the metal salt thereof are used. Depending on the hydrate, the organic acid can be arbitrarily selected within that range. Particularly preferred examples are as follows.
When using chlorinated isocyanuric acid and organic acid, it is particularly preferable to use 70 to 85% by weight of the organic acid, and when using hydrated alkali metal salt of chlorinated isocyanuric acid and organic acid. The organic acid is particularly preferably 65 to 80% by weight based on the weight of the molded product. Moreover, when using the hydrate of a chlorinated isocyanuric acid and its alkali metal salt, and an organic acid, 51 to 70 weight% of an organic acid is especially preferable with respect to the weight of a molded article.
[0014]
Further, when performing pressure molding, 0.1 to 5 parts by weight of a lubricant such as calcium stearate, magnesium stearate, sodium stearate, sodium benzoate, orthoboric acid or the like is blended in as necessary. Thus, pressure molding can be facilitated.
[0015]
Furthermore, depending on the purpose, inorganic corrosion inhibitors such as nitrites, silicates, polyphosphates, organic corrosion inhibitors such as carboxylic acids, metal soaps, sulfonic acids, amines, esters, phosphate esters, EDTA, A required amount of a corrosion inhibitor such as a chelate compound such as gluconic acid or nitrilotriacetic acid can be blended to suppress metal corrosion.

[0019]
(Comparative Example 1)
70 parts by weight of granular sodium dichloroisocyanurate dihydrate having a particle size of 100 to 1680 μ, 30 parts by weight of powdered fumaric acid, and 0.1 parts by weight of calcium stearate as a lubricant Press molding was carried out in the same manner as in Example 1 to obtain a cylindrical molded product having a diameter of 30 mm and a height of 24 mm.
[0020]
(Comparative Examples 2 to 8)
According to the composition described in Table 1, the chlorinated isocyanuric acid moldings of Comparative Examples 2 to 8 were obtained.
[0021]
(Solubility test)
A 6-cm wide, 120-cm-long vinyl chloride tray outlet is provided with a 12-mm weir for adjusting the water depth, and a 4 cm diameter, 13 cm long commercial septic tank barrel with an opening in the four directions of east, west, south, and north And put two cylindrical tablets with a diameter of 30 mm, a height of 24 mm, and a weight of 30 g of the molded products of Examples 1 to 6 and Comparative Examples 1 to 8 obtained in a medicine cylinder at 30 ° C. The water set to 1 was flowed at a rate of 4 liters per minute for 6 hours, and the average dissolved weight for 1 hour was calculated. The results are summarized in Table 1.
In Comparative Examples, there were problems in use such as a high dissolution rate and disintegration during dissolution (hereinafter abbreviated as “breakage”).
[0022]
[Table 1]
(Examples 7 to 12)
The slow-dissolving chlorinated isocyanuric acid molded products of Examples 7 to 12 were obtained in the same manner as in Example 1 at the blending ratios shown in Table 2 below.
[0024]
(Comparative Examples 9-13)
The chlorinated isocyanuric acid molded products of Comparative Examples 9 to 13 were obtained in the same manner as in Example 1 with the formulation shown in Table 2 below.
[0025]
(Safety test)
In a 100 ml beaker, 20 g of a test sample having the blending ratio shown in Table 2 was weighed, and 5 drops of palm oil (with a 5 ml Komagome pipette) were dropped, covered with powder and allowed to stand for 3 minutes. Thereafter, using a glass rod-shaped thermometer on the electric heater, mixing was performed at a stirring speed of 60 times per minute, and the mixture was heated at a heating rate of about 5 ° C. per minute. As a result of this test, the temperature at which the reaction started accompanied with smoke or flame was measured as the reaction temperature. In this test, since it was necessary to uniformly raise the temperature of the test object by applying a temperature gradient, a powdery mixture was used instead of a molded product. The measurement results are shown in Table 2.
As a result of the test, the mixtures of Examples 7 to 12 did not react at 100 ° C. or higher and were stable, but Comparative Examples 9 to 13 reacted at 80 ° C. or less and were unstable.
[0026]
[Table 2]
【The invention's effect】
As is apparent from Tables 1 and 2, a molded product obtained by pressure molding, containing a hydrated chlorinated isocyanuric acid and / or alkali metal salt thereof and an organic acid in a specific blending ratio, When immersed in water, it dissolves in a fixed amount over a long period of time without swelling or disintegrating in water. Further, it is a chlorinated isocyanuric acid molded product having excellent stability even when it comes into contact with substances such as oil and detergent.
[0028]
Therefore, the molded product of the present invention can be effectively used for sterilization and disinfection in a place where safety is required, such as sliding of a kitchen kitchen sink.
