Abstract

PROBLEM TO BE SOLVED: To substantially vanish a 'peculiar offensive smell' of a pyroligneous acid without reducing deodorizing-sterilizing capacity by including a heating reaction product of are fined pyroligneous acid and alcohol. SOLUTION: Smoke coming out of an outlet 1 of a flue is gathered by a bending clay pipe 2a and a cooling clay pipe 2b, and is cooled and liquefied. Since a crude pyroligneous acid 4 falls from a part of a smoke gathering part, this is introduced to a tank 6 by using a bamboo made gutter 5 or the like. When this crude pyroligneous acid is stationarily put in a deep acidproof vessel for a month or more, it is seperated into three layers of an upper layer 11, an intermediate layer 12 and a lower layer 13. A part of the intermediate layer 12 except for the upper and lower layers is an effective and safe intermediate layer pyroligneous acid. When this is distilled at the normal temperature, a usable refined pyroligneous acid is obtained. When the refined pyroligneous acid and alcohol are reacted with each other by heating, a deodorant is obtained.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD [0001] The present invention relates to a purified wood vinegar solution containing a reaction product of alcohol with heated alcohol,
The present invention relates to a deodorant which has solved the drawbacks of a conventional purified wood vinegar solution and a synthetic deodorant.

[0002]

2. Description of the Related Art In recent years, as general consumers have become more concerned with cleanliness and fragrances, the importance of deodorant or deodorant agents having a function of eliminating or masking various odors is also increasing.

[0003] Conventionally, "wood vinegar" is a liquid component obtained by cooling a smoke component generated during carbonization or carbonization of wood.
Is known to be effective as a deodorant for livestock manure in livestock farming by utilizing its deodorant and antibacterial properties (Sadayoshi Kishimoto, "Agricultural Chemicals Reduced by Wood Vinegar and Charcoal", p. 64 (199)
1) Rural and fishing village culture association). The use of wood vinegar liquid, which has a very low risk of destroying the environment, has recently been reviewed from the viewpoint of preserving the global environment.

[0004]

However, the above-mentioned wood vinegar has an advantage that it can be effectively used as a repellent for animals such as dogs and cats and insects. That is, wood vinegar having a peculiar odor is often felt as “offensive odor” not only to the above-mentioned animals but also to humans. Therefore, in practice, when the use of wood vinegar is accompanied by "a very strong odor" outdoors (in other words, when the odor of wood vinegar itself does not substantially matter), for example, livestock farming as described above Manure has been limited to deodorants and the like.

[0005] On the other hand, most of the fragrances, deodorants, or deodorants for general households which are currently commercially available are mostly “masking agents” in which a fragrance is added to a base composed of a synthetic surfactant. is there. Therefore, the fundamental odor "removal" capability of such masking agents has been questioned.

[0006] Furthermore, an increasing number of people feel that the "artificial" odor itself of the above-mentioned aroma, deodorant and deodorant itself is "odor odor" or unpleasant. In addition, such a residue of the chemical artificial substance in the air is not preferable from the standpoint of global environmental protection described above.

It is an object of the present invention to provide a deodorant which has solved the above-mentioned disadvantages of the prior art.

Another object of the present invention is to provide a deodorant which can effectively deodorize while preserving the global environment.

It is still another object of the present invention to provide a deodorant which can be suitably used in indoors such as ordinary homes and offices (especially air-conditioned indoors).

[0010]

Means for Solving the Problems As a result of intensive studies, the present invention has found that the reaction of purified wood vinegar with alcohol under heating does not substantially reduce the deodorizing effect of the wood vinegar, and It has been found that the peculiar odor of the wood vinegar itself is substantially eliminated (or significantly reduced).

The deodorant of the present invention is based on the above findings, and more specifically, is characterized by containing a reaction product of a purified wood vinegar solution and an alcohol under heating.

According to the present invention, there is further provided a method for producing a deodorant, which comprises a step of reacting a purified wood vinegar solution with an alcohol while heating.

In the above-described deodorant of the present invention, the "specific odor" of the wood vinegar is substantially eliminated without substantially reducing the deodorizing ability of the purified wood vinegar. Therefore, the deodorant of the present invention can be suitably used in indoors such as ordinary households and offices (in particular, indoors where ventilation is insufficient due to air conditioning or the like).

[0014] In addition, since the deodorant of the present invention does not substantially contain a surfactant or the like artificially synthesized from petrochemical products or the like, it can be regarded as a substantially complete “natural product or natural product”. It is expected that it will be recycled easily to the environment. Therefore, according to the present invention, by eliminating both the drawbacks of the conventional purified wood vinegar solution and the conventional synthetic deodorant, effective deodorization can be achieved while preserving the global environment.

[0015]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described more specifically with reference to the drawings as necessary. In the following description, “parts” and “%” representing quantitative ratios are based on weight unless otherwise specified.

(Wood Vinegar Liquid) Crude wood vinegar liquid is obtained by collecting and cooling and liquefying "smoke" generated during dry distillation or carbonization (for example, charcoal burning) of wood.

FIG. 1 is a schematic perspective view showing an example of a device for collecting wood vinegar. Referring to FIG. 1, smoke emitted from an outlet of a stack (such as a chimney of charcoal-burned sesame) 1 is bent at a distance of about 30 cm from the outlet 1 and a bent earth pipe 2 a and an earth pipe 2 b for cooling (liquid leakage prevention). From the point of view, both of the clay pipes are preferably "overcoated") and are cooled and liquefied.

From the viewpoint of the cooling efficiency, the above-mentioned earth pipe 2
In the cooling part of b, bamboo (Madatake, Moso bamboo etc.) 3-5
It is preferable to insert about six. As the clay pipe 2b,
The one having a diameter of about 24 cm is suitable, and the earth pipe 2 is preferably inclined at an angle of about 30 degrees from the horizontal from the viewpoint of the balance between the suction of smoke and the flow of smoke.

In the above apparatus, since the crude wood vinegar liquid 4 falls from a part of the smoke collecting section (bent soil pipe 2a), it is transferred to the tank 6 (acid-resistant) by using a bamboo toy 5 or the like. I just need to lead.

The wood vinegar solution thus obtained contains acetic acid (a main component of the wood vinegar solution), organic acids such as propionic acid, phenols such as cresol, carbonyl compounds such as acetone and furfural, and alcohols such as methanol. A neutral component, a basic component, and the like. On page 25 of the above-mentioned document, "Agricultural Chemicals Reduced by Wood Vinegar and Charcoal", as an example of the main components of black charcoal sesame wood vinegar, the organic matter content (1% of wood vinegar)
5.8%), acetic acid 58.4% (content in wood vinegar liquid organic matter, hereinafter the same applies in this section), propionic acid 1.9%, methanol 2.1%, furfural 1.7.
%, Cyclotene 2.3%, para and meta-cresol (total) 1.4%, ortho-cresol 1.2%, and the like.

(Purified Wood Vinegar Liquid) A method for purifying the above-mentioned crude wood vinegar liquid is shown in a schematic perspective view of FIG. When the crude wood vinegar is allowed to stand in a deep (preferably having a height of at least three times the diameter) acid-resistant container (such as a polytank) for one month or more (for example, about 1 to 6 months), this FIG. As shown in FIG. 2, the upper layer 11, the middle layer 12, and the lower layer 13 are separated. The upper layer 11 is an unstable wood vinegar liquid component having a variation in effect, while the lower layer 13 is a harmful wood vinegar liquid component having an adverse effect when applied. The portion of the middle layer 12 excluding these upper and lower layers is an effective and safe middle layer wood vinegar solution. This middle layer wood vinegar is 40% above the center of the container
It is said that a portion having a height of 20% below the height is preferable (the above-mentioned document, "Agrochemicals reduced with wood vinegar and charcoal", pp. 70-71).

By distilling the middle layer wood vinegar in a conventional manner, a purified wood vinegar usable in the present invention can be obtained.

As the purified wood vinegar solution, a commercially available product (eg, a product made by Saitama Agricultural and Industrial Products Sales Co., Ltd., trade name: spat wood vinegar solution) may be used, if necessary.

(Charcoal / plant treatment) The above purified wood vinegar solution can be used as it is for the production of the deodorant of the present invention, but further removal of harmful components and odor from the deodorant or fragrance. From the viewpoint of the application of water, it is preferable to use the purified wood vinegar solution after treating it with charcoal and / or a plant. Each of these charcoal / plant treatments is effective alone, but it is particularly preferable to use them in combination from the viewpoint of removing harmful components and odors or imparting aroma. These charcoal and plant are preferably used in a dry state.

An example of a preferred embodiment of the charcoal / plant treatment is shown below. For example, 150 L (liter) of purified wood vinegar liquid is put into a plastic tank having a capacity of about 200 L, and charcoal (for example, Cibachaco, trade name: Chibichaco) is preferably immersed in the plastic tank for about 500 g to 1000 g, and then room temperature For at least one month (preferably about six months or less). 7 ~ as required
It is preferable to stir using a stir bar or the like about once every 15 days. Such a charcoal treatment enables more complete removal of harmful tar components and the like.

When a chlorophyll-containing plant (for example, a leaf) is immersed in purified wood vinegar, it is preferable that about 500 to 1000 g of the plant be immersed in 150 L of purified wood vinegar as described above. By immersing such a plant, it becomes possible to more completely remove or mask the odor of the wood vinegar solution itself and / or to impart a more suitable fragrance to the deodorant. From the viewpoint of imparting aroma to the deodorant, dried leaves of laurel can be particularly preferably used as the above-mentioned plant.

After the above-described charcoal / plant treatment, a liquid component (for example, obtained as a yellow transparent liquid) is used for a reaction with an alcohol described below by a separation means such as filtration.

(Alcohol) In the present invention, an alcohol (anhydrous alcohol is preferred from the viewpoint of reactivity)
Can be used as it is in the reaction with the purified wood vinegar solution, but from the viewpoint of more complete removal or masking of the odor of the wood vinegar solution itself and / or imparting a more suitable fragrance to the deodorant. Preferably, the alcohol is also used after immersion of a chlorophyll-containing plant (eg, leaf). During this immersion, alcohol 1
It is preferable to soak a plant body of about / 5 volume or less.
As the above plant, from the viewpoint of imparting fragrance to the deodorant,
Dried leaves of laurel can be used particularly preferably. The above immersion treatment is preferably allowed to stand at room temperature for 10 days or more (more preferably about 15 days to 1 month). If necessary, it is preferable to stir using a stir bar or the like about once every 4 to 5 days. After such a plant immersion treatment, a liquid component (for example, obtained as a deep emerald green liquid) is used for the reaction with the purified wood vinegar solution described above by a separation means such as filtration.

The alcohol is not particularly limited, as long as the irritating odor of the wood vinegar can be substantially eliminated or masked by the reaction with the purified wood vinegar, but is not limited to the reactivity with the purified wood vinegar or obtained by the reaction. From the viewpoint of the odor of the obtained deodorant, a lower alcohol having 1 to 4 (more preferably 1 to 3) carbon atoms is preferable, and ethanol is particularly preferably used.

(Reaction between Wood Vinegar Solution and Alcohol) The deodorant (stock solution) of the present invention can be obtained by reacting the above-mentioned purified wood vinegar solution with alcohol under heating. Since an ester-like odor is obtained from the product after the reaction, it is presumed that the reaction involves an esterification reaction. That is, by the reaction, the “irritating odor” of the unreacted purified wood vinegar itself changes to an ester-like sweet scent. The reaction conditions are not particularly limited as long as the irritating odor is substantially eliminated or masked.
It is preferable to react about 5 to 20 parts (more preferably, 8 to 12 parts) of alcohol with respect to (weight) parts. The heating conditions are about 50 to 70 ° C (further 55 to 65 ° C).
C.), and a reaction time of about 5 to 30 minutes (more preferably about 12 to 20 minutes).

(Method of Using Deodorant) The deodorant (stock solution) of the present invention can be used as it is, if necessary for the purpose of deodorization, etc., but ordinary essential oils and the like can be used. Similarly to the above, it is preferable to dilute with a known solvent several times to several tens times and use it. When water is used as a solvent for dilution, the degree of dilution should be about 10 times or more, more preferably about 20 times to 100 times (particularly about 25 to 80 times) from the viewpoint of aroma and deodorizing effect. Is preferred.

Hereinafter, the present invention will be described more specifically with reference to examples.

[0033]

Example 1 (Production of deodorant) 150 L (liter) of a commercially available purified wood vinegar solution (trade name: Mousson, manufactured by Anritsu Corporation) was placed in a plastic tank having a capacity of about 200 L, and charcoal was added thereto. (Product name: Chibichaco, manufactured by Chaco Corporation) Approx. 1000
g and dried leaves of laurel were impregnated with about 1000 g and allowed to stand at room temperature for about 3 months. During the standing, the contents in the tank were stirred using a stirring rod about once every 15 days.

The mixture obtained after the standing was filtered using a stainless steel net to obtain a yellow transparent liquid (hereinafter referred to as "raw material A"). Such charcoal /
By the laurel treatment, harmful tar components and the like are more completely removed, the transparency of the wood vinegar is increased, the odor of the wood vinegar itself is further removed or masked, and a more suitable aroma is imparted. The purified wood vinegar solution obtained above was analyzed by the normal hexane method.
ppm and its pH was 3.1 (analysis result by Mr. Awane, director of Saitama Environmental Inspection and Research Association).

Separately from the above purified wood vinegar solution, about 1/10 volume of the dried leaves of laurel is immersed in 5 L of absolute ethanol (reagent grade ethanol, manufactured by Kosakai Pharmaceutical Co., Ltd.)
It was allowed to stand at room temperature for about one month. During this standing, the content was stirred using a stirring rod at a rate of about once every three days. The mixture obtained after the standing was filtered using a filter to obtain a deep emerald green liquid (hereinafter, referred to as “raw material B”).

200 ml of the “raw material A” obtained above,
“Raw material B” (200 mL) was placed in a beaker having a capacity of 500 mL, and heated in a 60 ° C. warm bath for about 15 minutes while stirring with a glass rod. Except for the jelly-like product generated in the upper portion of the mixture by this heating, a deodorant (stock solution) of the present invention was obtained. By heating with this ethanol, the pungent odor of the purified wood vinegar itself was substantially eliminated or masked, and the odor changed to a sweet ester-like aroma.

Example 2 (Deodorizing effect on pet odor) The undiluted solution of the deodorant obtained in Example 1 was mixed with water about 30 times, about 50 times, and about 7 times, respectively.
After diluting to 0-fold, spray with a household sprayer (trade name: Sakasa Spray Co., Ltd., manufactured by Sakata No Tane Co., Ltd.) against the odor (pet odor) of ordinary households as shown in Table 1 below (one dilution and erasure). Spraying amount of odorant: about 9 mL; spraying twice a day) was applied to actually test the presence or absence of the deodorant effect and the odor of the diluted deodorant itself. Was obtained by questionnaire survey. This survey was conducted by the general public 2
The test was performed on 0 subjects.

As shown in Table 1, the pet smells of the above-mentioned surveys were puppies, cats, birds, hamsters, and squirrels. The results of the investigation are shown in Table 1 below.

[0039]

[Table 1]

In the column of “Effect” in Table 1 above, “Yes” indicates that there was a clear deodorizing effect on pet odor.
When there was no effect or it was unclear, it was evaluated as "absent". In the column of "Smell of solution", the case where the smell of the diluted deodorant itself is felt good is defined as "Good", and the smell of the deodorant itself is bad (or the smell of the deodorant itself). Was not considered necessary). In the column of 50 times liquid or 70 times liquid, in the case of no effect, the urine of dog or cat was directly sprayed on the futon to which the urine was stained, but the source of the pet odor was not eliminated by a single spray. That is the case.

According to Table 1, the deodorant of the present invention shows an extremely effective deodorizing effect on malodor (pet odor).
Further, it can be understood that the odor of the deodorant itself is also good.

Example 3 (Deodorizing effect on household odor) Instead of the pet odor used in Example 1, the general household odor shown in Table 2 below was used.
Except for the types (garbage, toilets, odors in passenger cars, indoor tobacco, leather shoes, and socks)
The result of an experiment performed in the same manner as in Example 1 was obtained by a questionnaire survey. The results of the survey are shown in Table 2 below.

[0043]

[Table 2]

The meanings of the columns of “Effect” and “Smell of solution” in Table 2 are the same as those in Table 1.

According to Table 2, the deodorant of the present invention shows an extremely effective deodorizing effect even on bad odors (various bad odors in general households), and the odor of the deodorant itself is also reduced. You can see that it is good.

[0046] After the "raw material A" obtained in Comparative Example Example 1 was diluted to about 50 times with water, household stench (toilet odor) dilution of aerial spraying (once with a sprayer for the home to the consumption Spray amount of odorant: about 1 mL;
Sprayed each time after use). Although the deodorizing ability was recognized, the irritating odor of the wood vinegar itself remained and was unsuitable for deodorizing in general households (particularly indoors).

Example 4 5 g of commercially available agar (manufactured by Seikagyo Kyokai, trade name: Kaku agar, containing no preservative) was dissolved by boiling with 200 mL of water, and then the dish was made of glass (diameter 6 cm, deep). 2c
m), and solidified by natural cooling to produce four solidified agar samples (agar portion height: 1.5 cm).

The following treatments were applied to the four agar-containing petri dishes (No. 1 to No. 4) obtained as described above.

No. No. 1: as it is (no preservative or deodorant was added) 2: About 1 mL of commercially available purified wood vinegar used in Example 1
Spray evenly onto the agar sample using a spray.

No. 3: About 1 mL of the deodorant of the present invention obtained in Example 1 was sprayed uniformly on an agar sample using a spray.

No. 4: Commercially available antibacterial and fungicide deodorant (Kure Kogyo Co., Ltd., trade name: Cle Medisol) Approx. 1 m
L is sprayed evenly on the agar sample using a spray.

The petri dishes containing the four types of agar samples prepared as described above were placed indoors (living room,
(A place not exposed to direct sunlight) for 13 days, and observed for changes in the agar sample. The following results were obtained.

No. 1: From about one week after the start of standing, mold-like ones appeared, but the degree of the occurrence was mild, and the color tone of the mold was white. Almost odorless.

No. 2: No mold occurred during 13 days of standing. There is a smell of wood vinegar.

No. 3: No mold occurred during 13 days of standing. Almost odorless.

No. 4: Mold began to develop about 5 days after the start of standing, and on the 10th day, the surface of the agar was covered with almost black mold. Smell of petroleum solvent.

FIG. 3 is a graph showing the results of measurement of the “mold generation rate” (the ratio of the area of the mold generation portion to the total surface area of the agar) obtained in the above experiment. The numerical value of the mold generation rate was obtained by measuring the "measurement amount" by visual observation.

As can be seen from the above experimental results and the graph of FIG. 3, the deodorant of the present invention does not cause unnecessary odor to remain, and the original function of wood vinegar (preservative / sterilizing effect of food).
Can be understood effectively.

[0059]

As described above, according to the present invention, a deodorant characterized by containing a reaction product of a purified wood vinegar solution and an alcohol under heating; and adding a purified wood vinegar solution and an alcohol. There is provided a method for producing a deodorant, which comprises a step of reacting at an elevated temperature.

In the deodorant of the present invention described above, the purified wood vinegar solution does not substantially reduce the deodorizing and disinfecting ability,
The "unusual odor" of the wood vinegar is substantially eliminated.
Therefore, the deodorant / bactericidal agent of the present invention can be suitably used in indoors such as ordinary households and offices (in particular, indoors where ventilation is insufficient due to air conditioning or the like).

In addition, since the deodorant of the present invention does not substantially contain a surfactant or the like artificially synthesized from petrochemical products or the like, it can be regarded as almost completely “natural product or natural product”. It is expected that it will be recycled easily to the environment. Therefore, according to the present invention, by eliminating both the drawbacks of the conventional purified wood vinegar solution and the conventional synthetic deodorant, effective deodorization can be achieved while preserving the global environment.
