Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for effectively using a deodorant containing a benzoquinone analog as a raw material, which effectively acts on various malodors related to daily life, particularly deodorizing mercaptans.

[0002]

BACKGROUND OF THE INVENTION It has been known that a benzoquinone derivative has a high deodorizing ability for mercaptans, but its use method has been extremely limited. That is, benzoquinones could not exhibit their excellent deodorizing ability in their dry state or powder state.

Therefore, in order to use the benzoquinone derivative as a deodorant, it is used as a static deodorant by dissolving it in a liquid and spraying it on a malodorous source, or by filling the solution with a gas-permeable bag. There was a limitation in usage.
Further, since many benzoquinone derivatives have strong colors, there is a drawback that the color remains when they are sprayed as a liquid and attached to clothes, walls, and the like.

Further, JP-A-1-317443 and JP-A-1-317444 propose methods of mixing a benzoquinone derivative with a metal having a redox property to enhance its deodorizing effect. This method of use does not solve the above-mentioned problems associated with coloring.

[0005]

SUMMARY OF THE INVENTION The present invention has been made to solve these problems, and the problem is that it can be handled as a powder, so that it can be applied to resins, paper, fibers, etc. A benzoquinone derivative deodorant that can be processed and, therefore, can be used to impart the excellent deodorizing ability of benzoquinone derivatives to various daily products, and because it does not cause problems such as coloring, it is also excellent in printability. It is to clarify the usage method.

[0006]

In order to solve this problem, the present invention uses a benzoquinone derivative represented by (Chemical formula 1) as a deodorant component, which is selected from polar organic solvents such as water and lower alcohols. Inorganic substances such as silicon oxide, calcium oxide, calcium silicate, calcium carbonate, calcium oxide, iron oxide, zeolite, etc. which are dissolved in one or a mixture of two or more kinds and have high liquid-supporting property, such as single or mixed molded products, or water absorption Provided is a method of using a deodorant, which is used by being held on a carrier such as organic polymer beads such as a polymer.

Hereinafter, the present invention will be described in detail. The solvent used in the present invention is not limited as long as it can dissolve the benzoquinone derivative. In addition, since the benzoquinone derivative itself has an extremely high deodorizing ability, a solvent that is considered to have a low solubility for the benzoquinone derivative, such as water or a lower alcohol, can provide a sufficient concentration of the benzoquinone derivative for deodorization. It does not matter if you select an easy solvent.

Examples of the carrier having a high liquid-carrying property used in the present invention include inorganic oxides such as silicon oxide powder, calcium oxide powder, calcium silicate powder, calcium carbonate powder, iron oxide powder, and single or mixed molded products such as zeolite. Other than the carrier, an organic polymer such as water-absorbent polymer beads may be used. There is no limitation as long as it has a liquid-carrying property and can exhibit the characteristics as particles even if it absorbs water.

The solution concentration of the benzoquinone derivative is
Although the effect can be exhibited even in a small amount, 0.1% is a guideline, and it is desirable that the concentration is higher than this. Even when a solvent having a low solubility such as water or a lower alcohol is used as the solvent, it can be prepared at room temperature at this concentration, and a concentration near the saturation concentration may be used as a standard.

Further, the weight ratio when the benzoquinone derivative solution is supported on a carrier having a good liquid supporting property is as follows.
If it is about 10 to 50 parts with respect to 0 parts, both the deodorizing ability and the characteristics of the particles can be utilized. If you want to make the best use of the characteristics of the powder, you can reduce the amount of liquid, but in order to improve the dispersibility of the deodorant component in the powder, load a large amount in advance and then dry it in an oven etc. It is desirable to use a method in which only the liquid component is evaporated. Also,
Existing deodorants, deodorants, bactericides and antifungal agents may be used in combination as long as the effects of the present invention are not impaired.

The deodorant of the present invention thus obtained can effectively remove the malodor associated with daily life, especially mercaptans, which is a typical odor of sulfur, and has the effect, colorability and dispersion to date. It has made it possible to add highly effective dispersibility to fields where it could not be used due to poor printing properties and printability.

By keeping the polar solvent in the powder together with the benzoquinone derivative, the benzoquinone derivative is in a state where it is easy to exert its deodorizing ability, so that the amount of the benzoquinone derivative is small. Therefore, the color peculiar to benzoquinones is less likely to appear, and even if the solution volatilizes over a long period of time, the benzoquinone derivative itself does not directly adhere to clothes, walls, etc. Also occurs.

Further, by using the carrier, it becomes stronger by heat, so that it can endure heat treatment at about 200 ° C., such as processing into wallpaper or kneading into resin. Further, the effect does not decrease due to the processing.

【Example】

<Example 1> 50 mg each of P-benzoquinone, methoxybenzoquinone, 2,6-dimethoxy-1,4-benzoquinone, and methylbenzoquinone were dissolved in 50 g of water to obtain four kinds of benzoquinone aqueous solutions. This was well mixed with 10 g of a highly water-retaining powder mainly composed of silicon oxide and supported by absorbing water to obtain a powder having a water content of 83%.

Example 2 In order to check the heat resistance of the powder prepared in Example 1, 200 powder prepared in the same manner was used.
Heated in an electric furnace at 0 ° C for 1 hour. The result was a light powder. The water content at this time was 30%.

<Example 3> The powder prepared in Example 1 was prepared as a wallpaper by preparing 60 parts by weight of a plasticizer, 100 parts by weight of vinyl chloride and 1 part by weight of a prepared powder.

<Test Example 1> A slightly scratched methyl mercaptan standard solution ampoule (manufactured by Wako Pure Chemical Industries, Ltd., methyl mercaptan 0.1% standard solution 2 ml) was placed in a Tedlar bag having a capacity of 1 l, and the inside of the bag was cleaned. After filling the air
The ampoule was broken in the bag, and methyl mercaptan was vaporized and filled in the bag. The gas thus created was used as the test gas. 0.1 g of the deodorant powder prepared in Examples 1 and 2 was placed in a 60-ml glass vial bottle and sealed with a silicon stopper and an aluminum seal, and then 10 ml of air in the bottle was replaced with 10 ml of the test gas. The amount of methyl mercaptan in the bottle was measured using a gas chromatograph immediately after gas filling and after a certain period of time, and the deodorizing amount of methyl mercaptan by the deodorizing powder was compared. In addition, the same test was carried out for those dried in an electric oven and quinones which were not subjected to any treatment as comparative controls. The results are shown in Fig. 1.

It can be seen that by processing the deodorizing powder, the deodorizing ability of benzoquinone is enhanced and the excellent deodorizing ability of methyl mercaptan is exhibited. Further, it can be seen that the thermal processing has no effect on the effect.

<Test Example 2> The same test gas as in Test Example 1 was prepared. The wallpaper produced in Example 3 has a diameter of about 3c.
It was cut into a circular shape of m and put in a vial bottle similar to that used in Test Example 1 so that the surface of the wallpaper, which was the deodorant-treated surface, would not stick to the bottom of the bottle. The air in the bottle (10 ml) was replaced with the test gas (10 ml), and the amount of methyl mercaptan gas in the bottle was measured as in Test Example 1. For comparison, water only 50
The same test was carried out for the one in which ml was carried on the highly water-retaining powder, which was used as the wallpaper, and the four benzoquinones which were used as the wallpaper. The results are shown in Figure 2.

It can be seen that the wallpaper treated with the deodorant powder exhibits an excellent deodorizing ability for methyl mercaptan. It was observed that the methyl mercaptan gas was physically adsorbed on the wallpaper itself, but by repeating the additional injection of the test gas, the product subjected to the processing of the present invention has excellent immediate effect and durability. Recognize.

<Test Example 3> The color, texture and surface condition of the wallpaper processed after the treatment of the present invention and the wallpaper processed with benzoquinone as they were were compared.
The processed product of the present invention was colorless, had a good texture, and had a smooth surface, and was found to be suitable for printing and other processes.However, the product obtained by processing benzoquinone as it is has uneven coloring on the surface and is rough. I have a feeling that I felt
It was unsuitable for processing.

INDUSTRIAL APPLICABILITY As described above, the method of using the deodorant of the present invention can effectively remove the malodor related to daily life, especially mercaptans which are typical odors of sulfur.
In addition, it has made it possible to add a highly effective deodorant ability to fields where it has not been possible to develop due to effects, coloring properties, dispersibility, insufficient printability and the like. By processing, the color peculiar to benzoquinones is less likely to appear, and it is not necessary to worry about coloring problems, and printability is improved. Since it is more resistant to heat, it can withstand processing that requires heat of about 200 ° C., such as wallpaper processing and kneading into resin.
Further, the effect does not decrease due to the processing. As described above, the present invention is extremely practical.
