に対して有効な脱臭剤を提供することに関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention is directed to the treatment of malodor, foreign odor, or unpleasant odor components in trash cans, refrigerators, etc., particularly basic malodorous gases such as ammonia and amines, hydrogen sulfide, mercaptans, etc. The present invention relates to a deodorizing agent that is effective in removing acidic malodorous gases.

A method using a solution of iron ascorbate and its impregnating agent is known.

が開示されている。■ Regarding methods using crystalline aluminosilicate, that is, zeolite, JP-A-63-12320 discloses a method for removing ammonia, which is one of the malodorous components, and JP-A-63-20100 describes , it has been disclosed that zeolite adsorbs ammonia as well as pet feces and urine odors to some extent.
［発明が解決しようとする課題］
しかしながら、前記従来法はいずれも次の様な欠点を有
している。即ち、
■マスキングによる方法では根本的な悪臭成分の除去に
はならず、マスキング剤として使用される香料の種類に
よっては異臭となり不快感を催すことがある。[Problems to be Solved by the Invention] However, all of the above conventional methods have the following drawbacks. That is, (1) the masking method does not remove the fundamental malodorous components, and depending on the type of fragrance used as a masking agent, it may produce an unpleasant odor and cause discomfort.
■酸またはアルカリ性の薬液による中和法ではその取り
扱いには専門的な知識と技術が必要となり、他の薬剤と
の併用においてはとくに注意をようする。■Neutralization using acidic or alkaline chemicals requires specialized knowledge and skills, and special care should be taken when using them in combination with other chemicals.

感を催す。■ Coconut shell activated carbon is widely used as an adsorbent for adsorbing malodorous substances, but activated carbon does not have sufficient deodorizing effects on the malodors of ammonia and lower amines. Furthermore, activated carbon is black in color, and its appearance gives off a sense of uncleanness or disgust.

に低下してしまう。(2) Also, a deodorizing agent made by adding L-ascorbic acid to ferrous sulfate (FeSO4) is also available. Although this deodorizer is effective against salt-prone malodorous gases such as ammonia and amines, it does not exhibit sufficient deodorizing effects against acidic malodorous gases such as hydrogen sulfide and mercaptans. Furthermore, this deodorizing agent is oxidized by oxygen in the air, and its deodorizing ability is significantly reduced.

The zeolite disclosed in Japanese Patent No. 3-12320 absorbs some amines such as ammonia, but does not absorb any other malodorous components.

ものである。As mentioned above, all of the conventionally known drugs used to combat bad odors either have insufficient effects or are inconvenient to handle. The object of the present invention is (1) to provide a deodorizing agent that does not have such drawbacks, that is, is highly effective against various malodorous components and is easy to handle.

また、本発明の脱臭剤は、白色または淡色であり、嫌悪
感あるいは不潔感を催すことがない。Further, the deodorizing agent of the present invention is white or light-colored and does not cause a feeling of disgust or uncleanness.
さらには、金属イオン種類（たとえば、Ｎｉ。Furthermore, metal ion types (for example, Ni.
Ｃｕ、Ｚｒなど）を選択することによって、悪臭物質の
捕捉量の増加とともに暗色に変化させることができる。By selecting Cu, Zr, etc.), the color can be changed to dark as the amount of malodorous substances captured increases.
その結果、脱臭剤自体がインジケーターとなり、脱臭剤
の能力低下をしめし、その取り替え時期を知ることが出
来る。As a result, the deodorizer itself becomes an indicator, indicating that the deodorizer's performance has decreased, and it is possible to know when to replace it.
さらに、本発明の脱臭剤は悪臭ガス中に水分が含まれた
状態でもその性能を発揮する。Furthermore, the deodorizing agent of the present invention exhibits its performance even when moisture is contained in malodorous gas.
［実施例］ 以下に、この発明の詳細な説明する。[Example] The present invention will be explained in detail below.
