Description

【0001】
【発明が属する技術分野】
本発明は、多くの臭気に対する良好な消臭剤、詳しくはアミノクロロトルエンスルホン酸銅とタンニン酸第一鉄塩とを含有した消臭剤及び消臭剤組成物に関する。
【0002】
【従来の技術】
生活水準が高まるに伴い、一般生活をはじめとして多くの場面で臭気に対する関心が高まっている。消臭剤として最も一般的なものは、芳香剤や活性炭を主成分としたものであるが、芳香剤は性質上特有の臭いを持っており使用する場所が限られるばかりか、使用条件によっては逆に芳香臭が悪臭に感じられる場合がある。また、活性炭は、細孔中に臭気物質を吸着するため広い範囲での消臭が可能となるが、一度吸着した臭気物質が気温湿度等の条件により脱着をおこしたり、アンモニアなど低分子量の臭気物質は吸着し難いという欠点があった。
【0003】
一方、金属イオンを用いた化学的消臭効果による消臭剤も多く提案されているが、化学的消臭には対象としている臭気以外には消臭効果が低いという欠点があり、銅イオンは含硫黄物質に対する消臭能力は非常に高いが、アミン類、アルデヒド類等に対する消臭能力は比較的低く、第1鉄イオンは含窒素物質に対する消臭能力は非常に高いが、含硫黄物質に対する消臭能力は比較的低い。
例えば、タンニン酸の遷移金属塩を用いた消臭方法として特開昭54−8725号公報、特公昭54−18358号公報、特開平1−266275号公報等が報告されているが、トリメチルアミンをはじめとした窒素系の悪臭物質に対しては高い消臭効果を示すが、硫化水素、メチルメルカプタンといった硫黄系の悪臭物質に対する消臭効果が比較的低く、用いる条件によって十分な消臭効果を得ることが出来なかった。
また、それぞれの欠点を補うべく、例えば銅イオンと第1鉄イオンを混合して使用すると、還元作用と酸化作用という相反する消臭機構を持つため消臭作用が相殺され、消臭能力の低下をもたらしていた。
【0004】
一方、アルデヒド類に対する消臭成分として、特開平2−180634号公報、特開平3−296434号公報、特開平5−23588号公報、特開平6−225927号公報等で芳香族アミン類を用いる提案がされているが、これらのみではアルデヒド類以外の臭気物質に対する消臭能力はあまり望めないし、水溶性を持つ芳香族アミン類の銅塩と鉄塩を混合して用いても、銅イオンと鉄イオンの相殺作用を防ぐことは困難であった。
【0005】
更に、特開平8−299421号公報にはスルホン酸基を持つビニル化合物の金属塩を重合し不水溶性にする消臭ゲルが提案されているが、この方法ではアルデヒド類に対する消臭効果は望めなかった。また、チタン系をはじめとした金属の光触媒作用を利用したものもあるが、消臭速度が遅く、高価であるため一般には使用し難かった。
【0006】
【発明が解決しようとする課題】
臭気物質の数は非常に多いため、通常の消臭剤は、例えば、トイレ用、冷蔵庫用、タバコ用といった消臭できる臭気が限定され、汎用の消臭剤が望まれているが、例えば、銅イオンと第1鉄イオンを混合して用いるためには、消臭剤を酸性にしておく必要があるため、担体に含浸等により担持させた場合は担体の劣化をまねきやすく、消臭剤の形状は液状かゲル状等に限定されていた。これら欠点を補うためpHを中性〜塩基性にすると、消臭作用の相殺作用により反応性が低下したり、空気中酸素による酸化作用が急速に進展するといった問題点があった。
本発明はかかる問題点を解決した、多くの種類の悪臭に対して消臭効果をもち、安定で効率的且つ安価な消臭剤を提供することを課題とする。
【0007】
本発明者らはかかる課題を解決すべく鋭意検討を行った結果、非常に安価で、硫化水素、アンモニア、メチルメルカプタン、トリエチルアミン、アセトアルデヒド、ピリジンといった非常に広い範囲の臭気物質を非常に高い消臭力でしかも短時間に除去できる消臭剤を見いだし、本発明を完成するに至った。
すなわち、本発明はアミノクロロトルエンスルホン酸銅とタンニン酸第一鉄塩とを併用した消臭剤、及びこれを多孔質の担体に担持させた消臭剤組成物を提供するものである。
【0008】
以下、本発明を詳細に説明する。
本発明に用いられるアミノクロロトルエンスルホン酸銅は、アミノクロロトルエンスルホン酸を銅イオンと反応させることにより容易に得ることが出来る。すなわち、アミノクロロトルエンスルホン酸を水等の溶媒に溶解した後、銅イオンを加えることにより速やかに難水溶性のアミノクロロトルエンスルホン酸銅が形成される。銅塩の組成は取得方法により異なり、通常アミノクロロトルエンスルホン酸対銅が2.5〜3対1であるが、この組成比の塩に限定されるものではない。
【0009】
出発物質として用いられるアミノクロロトルエンスルホン酸は、通常C酸と表記される3−アミノ−6−クロロトルエン−4−スルホン酸や4−アミノ−2−クロロトルエン−5−スルホン酸といった異性体に関わらず、アミノクロロトルエンスルホン酸ナトリウムをはじめとして、分子内スルホン酸基がアルカリ金属やアンモニウムと塩を形成していてもよい。これらのアミノクロロトルエンスルホン酸や、その塩類は単独で使用してもよいし、混合して使用してもよい。
【0010】
本発明では、アミノクロロトルエンスルホン酸銅とタンニン酸第一鉄とを含有した消臭剤が提供される。両者の混合比率は消臭する悪臭の成分により自由に変更することができる。しかし、アミノクロロトルエンスルホン酸銅分が10%以下になると硫化水素等の硫黄系悪臭物質に対する消臭能力が低下し、また、95%以上になるとトリメチルアミン等窒素系悪臭物質に対する消臭性能が低下する。従って、一般的な悪臭にはアミノクロロトルエンスルホン酸銅1部に対して、タンニン酸鉄0.10〜0.25が好ましい。
【0011】
本発明の消臭剤は、多孔質の担体に担持させることにより、消臭剤組成物とすることもできる。
本発明の消臭剤は、難水溶性の粉末であるので通常金属イオンを担持成分として用いた際に脱落が生じやすい湿式成形でも、歩留まりを自由に設定することができ、必要であればカルボキシメチルセルロース、ポリビニルアルコール等のバインダー剤を用い非常に高い歩留まりで、任意の組成をもつ自由な形状の組成物とすることができる。この際の形状、組成、製造方法は、本発明の主旨に従うもので有れば特に制限するものではないが、歩留まりを向上させ、吸着による更なる消臭効果の向上が期待できる事から、多孔性の担体、特に形状の自由度が高いパルプを担体として用いる事が特に好ましい。
【0012】
本発明で用いるアミノクロロトルエンスルホン酸銅は、難水溶性で且つ反応性が高く、硫化水素、メチルメルカプタンといった硫黄系の臭気物質、ホルムアルデヒド、アセトアルデヒドといったアルデヒド類をはじめとした多くの臭気物質に対して非常に良好な消臭能力を持つ。また、非常に安定であるため、従来、単に銅塩と鉄塩とを混合して使用した場合に生じていた金属成分同士の相殺作用による消臭性能を低下を招くことがなく、例えば、タンニン酸第1鉄と併用することにより、上述した臭気物質の他に、アンモニア、トリメチルアミンといった窒素系の臭気物質に対しても非常に良好な消臭能力を併せ持つ、それぞれの成分の持つ比較的消臭性能の低い臭気物質に対する消臭を補い合う、広く多くの悪臭に対する消臭が可能となった。
【0013】
また、本発明の消臭剤は他の消臭剤成分と直接混合して用いることも可能である。安定性の高い本発明の消臭成分は、他の消臭成分の活性を維持しやすく、また、他の消臭成分からの影響を受けにくい。これも、本発明の優れた特徴の一つである。

以上説明してきたように、本発明によると、多くの悪臭ガスに対して優れた消臭能力を示す、容易に任意の方法で成形できる、安価な消臭剤が提供される。[0001]
[Technical field to which the invention belongs]
The present invention relates to a good deodorant for many odors, and more particularly to a deodorant and a deodorant composition containing copper aminochlorotoluenesulfonate and ferrous tannate .
[0002]
[Prior art]
As the standard of living increases, interest in odor has increased in many situations, including general life. The most common deodorants are those with fragrances and activated carbon as the main component, but fragrances have a characteristic odor and are not only used in limited places. On the contrary, there is a case where an aromatic odor is felt as a bad odor. Activated carbon adsorbs odorous substances in the pores, so it can be deodorized in a wide range. However, once adsorbed odorous substances are desorbed depending on conditions such as temperature and humidity, or low molecular weight odors such as ammonia are used. There was a drawback that the substance was difficult to adsorb.
[0003]
On the other hand, many deodorizers with chemical deodorization effects using metal ions have been proposed, but chemical deodorization has the disadvantage that the deodorization effect is low other than the target odor, copper ions are Although the deodorizing ability for sulfur-containing substances is very high, the deodorizing ability for amines and aldehydes is relatively low, and ferrous ions have a very high deodorizing ability for nitrogen-containing substances. Deodorizing ability is relatively low.
For example, JP-A-54-8725, JP-B-54-18358, JP-A-1-266275, etc. have been reported as deodorizing methods using transition metal salts of tannic acid. It has a high deodorizing effect on the nitrogenous malodorous substances mentioned above, but has a relatively low deodorizing effect on sulfurous malodorous substances such as hydrogen sulfide and methyl mercaptan. I couldn't.
In addition, in order to compensate for each drawback, for example, when copper ions and ferrous ions are mixed and used, the deodorizing action is offset because of the contradictory deodorizing mechanism of reducing action and oxidizing action, and the deodorizing ability is reduced. Had brought.
[0004]
On the other hand, as a deodorizing component for aldehydes, proposals using aromatic amines in JP-A-2-180634, JP-A-3-296434, JP-A-5-23588, JP-A-6-225927, etc. However, with these alone, the ability to deodorize odorous substances other than aldehydes cannot be expected so much, and even if copper salts and iron salts of aromatic amines having water solubility are mixed and used, copper ions and iron It was difficult to prevent the ion canceling action.
[0005]
Further, JP-A-8-299421 proposes a deodorizing gel which polymerizes a metal salt of a vinyl compound having a sulfonic acid group to make it water-insoluble, but this method can be expected to have a deodorizing effect on aldehydes. There wasn't. In addition, some use the photocatalytic action of metals such as titanium, but they are generally difficult to use because of their slow deodorizing speed and high price.
[0006]
[Problems to be solved by the invention]
Since the number of odorous substances is very large, ordinary deodorants are limited in odor that can be deodorized, for example, for toilets, refrigerators, and cigarettes, and general-purpose deodorants are desired. In order to use a mixture of copper ions and ferrous ions, it is necessary to make the deodorant acidic, so that when the carrier is supported by impregnation or the like, the carrier is likely to be deteriorated. The shape was limited to liquid or gel. In order to compensate for these drawbacks, when the pH is neutral to basic, there is a problem that the reactivity is lowered due to the counteracting action of the deodorizing action, and the oxidizing action by oxygen in the air progresses rapidly.
An object of the present invention is to provide a deodorant that is stable, efficient, and inexpensive, having a deodorizing effect on many types of bad odors and solving such problems.
[0007]
As a result of intensive studies to solve such problems, the present inventors have found that they are very inexpensive and have a very wide range of odorous substances such as hydrogen sulfide, ammonia, methyl mercaptan, triethylamine, acetaldehyde, and pyridine. A deodorant that can be removed with force and in a short time has been found, and the present invention has been completed.
That is, the present invention provides a deodorant using a combination of copper aminochlorotoluenesulfonate and ferrous tannate, and a deodorant composition in which this is supported on a porous carrier.
[0008]
Hereinafter, the present invention will be described in detail.
The aminochlorotoluenesulfonic acid copper used in the present invention can be easily obtained by reacting aminochlorotoluenesulfonic acid with copper ions. That is, after dissolving aminochlorotoluenesulfonic acid in a solvent such as water, copper ions are rapidly formed by adding copper ions to form water-insoluble aminochlorotoluenesulfonic acid copper. The composition of the copper salt varies depending on the method of acquisition, and the ratio of aminochlorotoluenesulfonic acid to copper is usually 2.5 to 3 to 1, but is not limited to the salt having this composition ratio.
[0009]
Aminochlorotoluenesulfonic acid used as a starting material is an isomer such as 3-amino-6-chlorotoluene-4-sulfonic acid or 4-amino-2-chlorotoluene-5-sulfonic acid, which is usually expressed as C acid. Regardless, sodium aminochlorotoluenesulfonate and other intramolecular sulfonic acid groups may form salts with alkali metals and ammonium. These aminochlorotoluenesulfonic acids and salts thereof may be used alone or in combination.
[0010]
In the present invention, a deodorant containing copper aminochlorotoluenesulfonate and ferrous tannate is provided. The mixing ratio of the two can be freely changed depending on the malodorous component to be deodorized. However, when the copper content of aminochlorotoluene sulfonate is 10% or less, the deodorizing ability for sulfurous malodorous substances such as hydrogen sulfide is reduced, and when it is 95% or more, the deodorizing performance for nitrogenous malodorous substances such as trimethylamine is lowered. To do. Therefore, for general malodor, iron tannate 0.10 to 0.25 is preferred with respect to 1 part of copper aminochlorotoluenesulfonate.
[0011]
The deodorant of the present invention can be made into a deodorant composition by supporting it on a porous carrier.
Since the deodorizer of the present invention is a hardly water-soluble powder, the yield can be freely set even in wet molding, in which metal ions are likely to fall off when a metal ion is used as a supporting component. Using a binder such as methylcellulose and polyvinyl alcohol, the composition can be a free-form composition having an arbitrary composition with a very high yield. The shape, composition, and production method in this case are not particularly limited as long as they are in accordance with the gist of the present invention, but since the yield can be improved and further improvement in the deodorizing effect by adsorption can be expected, it is porous. It is particularly preferable to use as a carrier a hydrophilic carrier, particularly pulp having a high degree of freedom in shape.
[0012]
The copper aminochlorotoluenesulfonate used in the present invention is poorly water-soluble and highly reactive, and it is suitable for many odorous substances such as sulfur odorous substances such as hydrogen sulfide and methyl mercaptan, and aldehydes such as formaldehyde and acetaldehyde. And has a very good deodorizing ability. In addition, since it is very stable, the deodorizing performance due to the canceling action between metal components, which has conventionally occurred when a copper salt and an iron salt are simply mixed, is not reduced. By using in combination with ferrous acid, in addition to the above-mentioned odorous substances, it also has a very good deodorizing ability for nitrogen-based odorous substances such as ammonia and trimethylamine. It has become possible to deodorize a wide variety of bad odors, complementing the deodorization of low-performing odor substances.
[0013]
The deodorant of the present invention can also be used by directly mixing with other deodorant components. The highly stable deodorant component of the present invention is easy to maintain the activity of other deodorant components and is not easily affected by other deodorant components. This is also one of the excellent features of the present invention.

Comparative Example 5
An excess amount of tannic acid aqueous solution was added to an aqueous solution of ferrous sulfate (ferrous sulfate heptahydrate: a special grade reagent manufactured by Wako Pure Chemical Industries, Ltd.) and stirred thoroughly, and the pH was adjusted with 120 g / l sodium hydroxide. As a result, an iron tannate suspension was obtained.
Dissolve pulp (DP) with a dry weight of 8 kg and carboxymethylcellulose with a dry weight of 2 kg are thoroughly disaggregated and mixed, and 3 kg of the above iron tannate suspension is added and stirred well. Got. The sample was black and had no abnormality on the surface, and when dried, no effect on the pulp as the carrier was observed. When the iron content of this sample was measured by an atomic absorption method, iron was 2.6%.

Test Example Deodorizing experiments were performed using the samples obtained in Examples 1 to 4 and Comparative Examples 1 to 5.
The deodorization experiment was performed by a method in which 50 ppm of the target gas was sealed in a 1 liter Erlenmeyer flask and samples were added by 1.0 g by dry weight, and then the gas concentration was measured after 10 minutes and 30 minutes. The target gas used was hydrogen sulfide, trimethylamine, and acetaldehyde, and the gas concentration was measured by the detector tube method. The test results are shown in Table 1.
In the comparative example, high deodorizing ability is shown depending on the target gas type, but high deodorizing ability cannot be obtained for many gas types, and there is a concern about the influence on the carrier.
