Agent.

2. Description of the Related Art In recent years, there has been an increasing interest in odors present in the living space of consumers, and there has been a demand for a deodorant for removing unpleasant odors around us. Above all, in actual daily life, there are often many types of odor sources at the same time, so a single product can remove many types of odors,
A deodorant having an effective deodorizing function even when a plurality of malodor sources are mixed is expected. Among various odor sources,
The need for deodorization, especially for tobacco odors, is rapidly increasing, but the main component of this tobacco odor is acetaldehyde. In addition, as seen in sick house / sick building syndrome, health disorders caused by formaldehyde have been attracting attention. As an aldehyde gas removing agent, an amine aldehyde removing agent has been studied.

It is known that an amine compound has a high affinity for an aldehyde gas, and that an aldehyde gas contained in the exhaust gas can be removed by bringing an exhaust gas containing the aldehyde gas into contact with an amine compound solution (JP-A-51-44587). No.). However, the liquid amine compound emits a strong unpleasant odor, and thus is not suitable for application to a living space, for example, a living room or a kitchen or other daily life. Further, a gas absorbent in which an amine compound is supported on a heat-resistant inorganic substance is known, and this gas absorbent has a characteristic that can withstand heat treatment when added to a resin, papermaking, or film.

For example, activated carbon has an ammonium salt, aniline, etc. supported thereon, and a gas absorbent (JP-A-53-29292 and JP-A-56-53744). A gas absorbent carrying a compound having a secondary amino group (JP-A-9-28778) and a gas absorbent carrying a polyamine compound between layers of a layered phosphate (α-zirconium phosphate) are known (tsunami). Ancient PHARM.TECH.JAPAN Vol.
12. No.12 PP77-87 (1996)).

[0005] Further, a carbon dioxide gas absorbent in which amino alcohol is supported on silica (JP-A-53-23899), a deodorant in which polyallylamine is supported on silica (JP-A-63-141642), and N There is known a carbon dioxide absorbent (Japanese Patent Application Laid-Open No. 4-200742) in which an amine compound having a molecular weight per atom of 110 or less and a boiling point of 100 ° C. or more and water are supported on silica gel.
However, these gas absorbents not only have an absorption capacity for aldehyde gas lower than the practical level, but also have a reduced aldehyde adsorption capacity when added to fibers or paints.

As a result of a separate study, the present inventors have found that porous silicon dioxide having specific properties, which carries a polyamine compound having a primary amino group, has both heat resistance and deodorizing performance against acetaldehyde and formaldehyde. Was found to be extremely excellent. (JP 11
-206864 publication)

The present inventors have reported that porous silicon dioxide carrying a compound having a primary amino group exhibits extremely excellent deodorizing performance when used alone, but it is difficult to use basic silicon dioxide such as ammonia gas. It was recognized that when mixed with a material having a high deodorizing effect on gas, there was a problem that the deodorizing performance of the aldehyde-based malodor that should have been exhibited was greatly reduced. Furthermore, this problem is caused by a conventional gas absorber made of activated carbon impregnated with an aromatic primary amine or a deodorant for aldehydes such as a polymer compound having an amino group,
It turns out that this is a phenomenon that generally occurs even when mixed with a basic gas deodorant, which is usually an acidic substance.Therefore, a deodorant that can efficiently deodorize an aldehyde gas and a basic gas with one agent is known. , Confirmed that there is virtually no.

On the other hand, there has been proposed a method in which an organosilicon compound containing an amino group is supported on the surface of silica to exhibit the deodorizing performance of acetaldehyde (JP-A-9-173830). It was also found that, even with this material, when a highly effective deodorant is used in combination with a basic gas or a sulfur-based gas, the deodorizing performance that should be exhibited originally cannot be sufficiently exhibited.

[0009]

The present invention has a high function of deodorizing odors of aldehyde-based neutral gas such as acetaldehyde and formaldehyde by itself, and has another odor such as basic gas and sulfur-based gas. Even when other deodorants having the ability to deodorize acidic gases are mixed, a deodorant which can sufficiently exhibit the deodorant performance inherent in each individual deodorant, and the deodorant An object of the present invention is to provide a mixed deodorant composition comprising a specific other deodorant.

[0010]

SUMMARY OF THE INVENTION The present invention provides a deodorant comprising a carrier having a compound having a primary amino group in the molecule and an organosilicon compound having an amino group, and a deodorant comprising the deodorant and a silicic acid. The present invention relates to a deodorizing composition comprising at least one substance selected from the group consisting of aluminum, tetravalent metal phosphate, hydrated zirconium oxide and zinc oxide.

[0011]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail. ○ Carrier As the carrier in the present invention, any of organic and inorganic substances can be used as long as they support a compound having a primary amino group and exhibit acetaldehyde deodorizing performance. Examples of the organic carrier include soybean powder, blood powder, polyester resin, and polyacrylic resin.On the other hand, examples of the inorganic carrier include porous silicon dioxide, activated carbon, sepiolite, and mica. From the viewpoint, the inorganic carrier is more preferable.

Among the inorganic carriers, the specific surface area is 400 to 900 m ^{2 because of} its excellent acetaldehyde deodorizing performance.
/ G of porous silicon dioxide is a preferred support. If the specific surface area of silicon dioxide does not reach 400 m ² / g, the contact area between the compound having a primary amino group and the malodorous gas is reduced, and the gas adsorption amount is impaired. When the specific surface area exceeds 900 m ² / g, the compound having a primary amino group is adsorbed in a large amount, and is likely to cause discoloration by heating when processed into fibers or the like. The specific surface area can be easily measured by the BET method calculated from the nitrogen adsorption amount.

[0013] The porous silicon dioxide preferably has an average pore diameter of 0.1 to 10 nm. A particularly preferred average pore diameter is 2 to 8 nm. If the average pore diameter of the porous silicon dioxide is larger than 10 nm, the specific surface area decreases, the amount of the compound having a primary amino group supported decreases, and the performance of adsorbing odorous gas decreases. If an attempt is made to make the specific surface area sufficiently large despite the fact that the average pore diameter is too large, the porosity of the porous body becomes too large, the mechanical strength becomes small, or a compound having a primary amino group is used. There is a problem that the carrying capacity is weakened and a compound having a primary amino group is released by a slight heating. On the other hand, when the average pore diameter is smaller than 0.1 nm, the specific surface area of silicon dioxide increases, but the compound having a primary amino group is less likely to enter the pores, and as a result, the compound having a primary amino group Cannot be increased, and the odor gas absorption capacity decreases. The average pore diameter (D) is
It is easily calculated from the pore volume and the specific surface area obtained by the BET method using the following formula.

[0014]

(Equation 1) (V: pore volume [ml / g], Sc: specific surface area [m ² / g])

The preferred water content of the porous silicon dioxide in the present invention is 0.5 to 20% by weight, more preferably 8 to 15% by weight. When the water content is less than 0.5% by weight, the supporting capacity for the compound having a primary amino group in the present invention is small because the surface has few silanol groups. Conversely, when the water content is more than 20% by weight, When processed into fibers or the like, it causes coloring and deterioration. The water content of the porous silicon dioxide can be easily measured according to JIS K7120-7122. Commercially available products of porous silicon dioxide include silica gel and nip seal (hydrous silicon dioxide containing fine particles).

A compound having a primary amino group in a molecule A compound having a primary amino group in a molecule is an aliphatic compound if it has at least one primary amino group in the molecule. Any of amines, aromatic amines and alicyclic amines can be used. For example, an aliphatic amine represented by the following formula or an aromatic amine such as aniline can be used.

The preferred loading amount of the compound having a primary amino group on the carrier is 0.02 to 10.0 mmol /
g. When the supported amount is less than 0.02 mmol / g, the aldehyde-based gas adsorption ability is reduced. Conversely, when the supported amount exceeds 10.0 mmol / g, it has a primary amino group when processed into fibers or the like. The compound is dissociated from the carrier to cause discoloration, and the compound having a primary amino group itself becomes a source of offensive odor. In addition, the acetaldehyde and formaldehyde adsorption amounts also decrease. The loading amount of the compound having a primary amino group can be easily measured and calculated from the nitrogen content detected by organic element analysis.

The organosilicon compound containing an amino group The organosilicon compound containing an amino group in the present invention can absorb a aldehyde gas and a functional group such as a hydroxyl group or an alkoxy group capable of chemically bonding to a hydroxyl group on the surface of the carrier. An organic silicon compound having an amino group. Specific examples thereof include γ-aminopropyltrimethoxysilane, γ-aminopropyltriethoxysilane, N-β (aminoethyl) -γ-aminopropyltrimethoxysilane, and N-β-aminopropyltrimethoxysilane. β
(Aminoethyl) -γ-aminopropyltriethoxysilane, γ-glycidoxypropyltriethoxysilane,
And dimethyltrimethyl-silylamine.

The preferred amount of the amino group-containing organosilicon compound in the present invention is 0.01 to 3.0 mmol / g based on the total weight of the deodorant. The loading amount of the organosilicon compound containing an amino group is 0.01 mmol
When the amount is less than 1 / g, the deodorizing performance as an aldehyde gas alone is not sufficient, and in addition, a composite mixed with another deodorant having a deodorizing effect on a basic gas, an acidic gas, and a sulfur-based gas. When a deodorant composition of the type is used, the aldehyde gas deodorizing properties of the entire deodorant composition are significantly reduced. Further, the content of the organosilicon compound containing an amino group is 3.0 m.
When the amount is more than mol / g, the aldehyde gas deodorizing performance of the deodorant of the present invention is not improved in proportion to the added amount, and it is uneconomical. Absent.

O Deodorant Composition The deodorant of the present invention is effective against aldehyde gases such as acetaldehyde and formaldehyde as described above. At the same time, it is preferable to mix and use with other deodorants described below for the purpose of deodorizing malodors other than the aldehyde-based gas at the same time, in particular, since the features of the deodorant of the present invention are utilized.

Specifically, for example, a tetravalent metal phosphate and aluminum silicate can be mixed to deodorize a basic gas such as ammonia and trimethylamine. Preferred specific examples of the tetravalent metal phosphate include zirconium phosphate, titanium phosphate, and tin phosphate. These compounds include crystalline and amorphous compounds having various crystal systems, such as α-type crystals, β-type crystals, γ-type crystals, and nasicon-type crystals, and any of them can be used. Further, among the tetravalent metal phosphates, those having ion exchange properties are particularly preferably mixed with the deodorant of the present invention.

In order to simultaneously deodorize sulfur-based gases such as hydrogen sulfide and methyl mercaptan, tetravalent metal phosphates such as zirconium phosphate, titanium phosphate and tin phosphate may be added to copper, zinc, manganese, and the like. It is preferable to mix at least one kind of metal ion selected from the above or zinc oxide with the deodorant of the present invention.

As the tetravalent metal phosphate, any of crystalline and amorphous materials having various crystal systems such as α-type crystal, β-type crystal, γ-type crystal, and Nasicon type crystal can be used. In particular, those having ion exchangeability can be preferably used. Among tetravalent metal phosphates supporting metal ions,
A tetravalent metal phosphate supporting copper ions is particularly preferable because of its high deodorizing effect on hydrogen sulfide and the like. To support a metal ion on a tetravalent metal phosphate, a tetravalent metal phosphate is
What is necessary is just to make it contact with the salt solution of a metal ion, and to carry by ion exchange. The carried amount of the metal ion can be freely adjusted as desired up to 100% within the ion exchange capacity of the tetravalent metal phosphate. Further, zinc oxide having a large specific surface area is preferable because of its high deodorizing performance.

In order to deodorize malodor caused by acidic gas such as acetic acid, isovaleric acid and butyric acid, it is preferable to mix hydrated zirconium oxide with the deodorant of the present invention. The hydrated zirconium oxide used in the deodorant of the present invention can be produced by hydrolyzing a zirconium-containing solution such as an aqueous zirconium oxychloride solution with water or an alkaline solution. The hydrated zirconium oxide may be referred to in various ways, such as zirconium oxyhydroxide, zirconium hydroxide, hydrous zirconium oxide, hydrated zirconium oxide, and any of the hydrated zirconium oxides used in the present invention. Is the same as

Each of the deodorants used in the deodorant composition of the present invention is usually obtained in the form of a powder, and preferably has an average particle size of 0.01 to 50 μm, more preferably 0.1 to 50 μm.
01 to 20 μm, more preferably 0.1 to 5 μm
m. If the average particle size is less than 0.01 μm, there are problems such as difficulty in handling and easy reaggregation, which is not preferable. Further, when it is larger than 50 μm, it is difficult to disperse uniformly in the binder resin liquid when dispersed in the binder resin liquid and used as a surface treatment agent in post-processing such as fibers.
Further, when it is added to a molding resin, there are problems such as clogging of a filter of a molding machine and poor dispersion, which are not preferable.

The deodorant or the deodorant composition of the present invention may be granulated according to the purpose of use. In the case of the deodorant composition of the present invention, each deodorant to be mixed may be granulated for each component, or may be granulated after mixing. As a method for producing the granular material, any method for granulating the powder can be generally used. For example, there is a method in which alumina sol, clay, or the like is used as a binder to form a granular material. The particle size can be variously adjusted depending on the hardness, density, crushing strength and the like of the granular material.
It is preferably set to be at least mm.

In the present invention, a deodorant carrying a compound having a primary amino group and further carrying an organosilicon compound having an amino group, the above-mentioned tetravalent metal phosphate, aluminum silicate, hydrated oxide The mixing ratio with one or more substances selected from zirconium, tetravalent metal phosphate and zinc oxide is not particularly limited, and may be appropriately changed depending on the content of the malodor source existing in the environment where the deodorant is used. Can be used.

Production Method Preferred production examples of the deodorant of the present invention are described below.
It is not limited to this. The deodorant of the present invention comprises a step of supporting a compound having a primary amino group in a molecule on a carrier such as porous silicon dioxide, and a step of further supporting an organic silicon compound on the compound obtained thereby. It is manufactured through First, as for the production process for supporting a compound having a primary amino group, a wet method will be described as an example of the production method. When a solution obtained by diluting a compound having a primary amino group with water or the like is mixed with a carrier such as porous silicon dioxide, a carrier which uniformly supports the compound having a primary amino group can be obtained. Usually, an excessive amount of the compound having a primary amino group is mixed with the carrier. After the mixing, the compound is washed with pure water to remove the compound having an excessive primary amino group attached to the surface. Thereafter, the washed material is dried at 50 to 120 ° C.

Next, the step of supporting an organic silicon compound having an amino group on a carrier such as porous silicon dioxide or the like (hereinafter simply referred to as an amine support) supporting the compound having a primary amino group is described below. Any of a wet method, a dry method, and the like can be used. For example, the wet method will be described in detail. First, a solvent (usually water) is added to a container in which an organosilicon compound containing an amino group is weighed so as to be equal to or more than an amount capable of supporting an amine-containing organosilicon compound on the surface of an amine carrier. A solution prepared by hydrolyzing an amino group-containing silicon compound is prepared. And
An amine carrier is charged and immersed in this adjustment liquid. The temperature is usually at room temperature, and the solution is impregnated with the amine carrier by stirring for about 10 minutes to 24 hours. further,
The desired deodorant can be obtained by washing the impregnated amine carrier with water and drying.

Another preferred method for producing an organosilicon compound having an amino group on an amine carrier is a dry method. This dry method is more advantageous than the wet method because there is no washing step, so that there is no need to discharge the amine wastewater, which leads to environmental pollution, and there is no need for a drying step after the washing step. In the dry method, an organosilicon compound containing an amino group is previously hydrolyzed on an amine carrier in a commonly used mixing device such as a Henschel mixer, a vibration mill, a ball mill, a ribbon mixer, a jet mill, and a grinder. After that, it is manufactured by directly mixing or grinding the carrier. After the production, if necessary, the deodorant can be classified using a general classifier such as a vibrating sieve or a cyclone.
