Description

[Detailed description of the invention]

[Industrial Application Field] The present invention relates to deodorizing and deodorizing materials containing plant components collected from plants such as tea, camellia, sasanqua, and evergreen broad-leaved trees such as laurel, and which have little nonvolatile residue. [Prior Art and Problems to be Solved by the Invention] Conventionally, as deodorizing and deodorizing materials containing plant components collected from plants such as evergreen broad-leaved trees, there are, for example, those shown in Japanese Patent Publication No. 18098/1983. It has been known. In this method, the distillate components obtained from these hardwood materials by means of solvent extraction or vacuum distillation are used as they are, or those obtained by simply distilling off the solvent in the distillate components are used. However, impurities such as those with high boiling points at room temperature or polymerization products generated due to long-term treatment in solvents still exist in the products that have been extracted with solvent or distilled under reduced pressure.
It is not acceptable for them to exist in deodorizing materials and turn into non-volatile residues, and there are some that emit a strange odor by themselves, and even though they do not emit a strange odor in that state,
When deodorizing and deodorizing materials are heat-treated and used to actively evaporate into the atmosphere, the heat may accelerate the denaturation of non-volatile residues and cause off-odors. There are drawbacks such as the non-volatile residue significantly inhibiting the deodorizing and evaporation performance of the deodorizing material. Therefore, it has been proposed to further process the extract to minimize the amount of non-volatile residue, but to date, there has been little problem in using the non-volatile residue when forced evaporation is carried out. The actual situation was that no consideration had been given to reducing the number of items to a minimum so that they would not be left behind. [Means for Solving the Problems] In view of the above-mentioned circumstances, an object of the present invention is to provide a deodorizing and deodorizing material containing plant components and producing less non-volatile residue, which can eliminate these drawbacks. It was created as a mother liquor, which is made from the leaves of plants such as evergreen broad-leaved trees, which are first treated with solvent extraction, and then this first treated mother liquor is further heated under atmospheric pressure at a temperature of 130℃ or less. It is characterized in that the active ingredient is a secondary treatment component that is distilled at a high temperature and that when the distillate component is heat-treated and forcibly evaporated, the amount of non-volatile residue is minimal. It is something. With this configuration, the present invention is a deodorizing and deodorizing material that contains plant components collected from plants such as evergreen broad-leaved trees, but it is possible to eliminate non-volatile residues that cause off-odor in the material itself. It is designed so that it does not include The plants used in the present invention include tea,
The leaves of commonly known plants such as camellia, camellia, sasanqua, camphor tree, laurel, and sakaki are used as materials, and these can be used alone or in combination. semi-dried food,
It may also be dried. Furthermore, methyl alcohol, ethyl alcohol, n-
propyl alcohol, isopropyl alcohol,
n-butyl alcohol, diethylene glycol,
Lower alcohol solvents such as propylene glycol, ketone solvents such as acetone and methyl ethyl ketone, ether solvents such as diethyl ether, dioxane, and tetrahydrofuran can be used alone or as a mixture of a plurality of solvents, and further as a mixed solvent with water. . Then, solvent extraction is performed by refluxing the plant materials such as evergreen broad-leaved trees in a solvent, or heating and stirring in a solvent, and extraction processing is performed by filtration or vacuum distillation to separate the raw material residue. ,
As a result, a primary treated mother liquor is obtained. This mother liquor is further subjected to secondary treatment by distillation under atmospheric pressure. In addition, the present invention has a temperature of approximately 130°C or lower (preferably 120°C or lower).
It contains as an active ingredient a distillation component that is distilled at a temperature of up to Odor and deodorizing materials can contain the solvent that is distilled together as an active ingredient, but
Furthermore, the product from which the solvent has been removed can be used as an active ingredient in deodorizing and deodorizing materials. At this time, when removing the solvent, if the boiling point of the solvent is below the upper limit temperature of distillation, and if the boiling point is considerably lower than the upper limit temperature of distillation, when distilling the mother liquor,
After the low-boiling point solvent is distilled off, the distilled component that is distilled out at a temperature between the boiling point of the solvent and the upper limit temperature of distillation can be collected as an active ingredient for deodorizing and deodorizing materials. If the temperature is close to the upper limit temperature, the solvent and the effective components of the deodorizing and deodorizing material can be separated from the solvent by means such as vacuum distillation of what is distilled out together with the solvent. In addition, in the case of a solvent with a boiling point above the upper limit temperature of distillation, the mother liquor is distilled as it is under atmospheric pressure, and the distilled component distilled at a temperature below the upper limit temperature of distillation is used as a deodorizing and deodorizing material containing almost no solvent. It is the active ingredient of It goes without saying that the active ingredients of the deodorizing and deodorizing materials obtained in this way can be used alone or in combination with other deodorizing and deodorizing materials. The liquid material containing the deodorizing and deodorizing material of the present invention as an active ingredient can be used in a general manner, such as by diluting it with an appropriate solvent or spraying it as an aerosol. A suction medium formed using a capillary tube assembly, a glass mat, etc. is filled in a tank provided so as to protrude, and by heating the suction medium, the extinguishing agent sucked up through the suction medium is heated. It can also be used in a deodorizing device configured to forcibly evaporate odor and deodorizing materials into the atmosphere. [Effects] Since the present invention is constructed as described above, the active ingredients of deodorizing and deodorizing materials containing plant components obtained from the leaves of plants such as evergreen broad-leaved trees and having little non-volatile residue are , which was first treated by solvent extraction, and then further processed at atmospheric pressure for 130°C.
Since the active ingredient is obtained through secondary treatment by distillation at a temperature below ℃, the main ingredient is something that easily vaporizes, and it is an extremely volatile substance with no distillation residue. It will be composed by. By ensuring that the distillation temperature during secondary treatment does not exceed 130°C, aromatic substances such as flavone-based substances, unsaturated aldehydes, unsaturated carboxylic acids, or benzaldehyde that volatilize at higher temperatures can be removed. Highly non-volatile substances such as group compounds that change easily over time and cause off-odors are extremely small and are hardly contained in the ingredients. If you try to use it by forcing evaporation inside the tank, as with conventional products, a large amount of non-volatile residue will remain in the tank, or non-volatile substances will accumulate in the heating part and cause clogging. This product provides excellent deodorization and deodorization over a long period of time, without causing early deterioration in the wicking properties of the liquid material or by heating, which promotes the denaturation of non-volatile substances and causing them to warp and emit strange odors. Performance can be maintained. Hereinafter, the present invention will be explained in more detail with reference to Examples. Example 1 Using powdered dried leaves of tea plants as the leaves of plants such as evergreen broad-leaved trees, 150 g of this powder and 500 ml of ethanol were added.
and was placed in a Soxhlet extractor and heated under reflux for 24 hours. Then, the raw material residue is removed from the extract by filtration to obtain 545 g of primary treated mother liquor. This mother liquor is then placed in a round-bottomed flask equipped with a Liebig condenser and heated to distill. And by distilling substances up to a temperature of 130℃,
430g of deodorizing and deodorizing material as a secondary treated ethanol solution was obtained. Examples 2 and 3 Based on the same method as in Example 1, the mother liquor of the primary treatment was extracted using plants as shown in Table 1,
This mother liquor was further distilled and subjected to secondary treatment to obtain the deodorizing and deodorizing material of the present invention. Examples 4 and 5 A mother liquor was obtained based on the same method as in Example 1, and this mother liquor was further subjected to distillation treatment. In this case, the solvent was first distilled off as a distillate component up to its boiling point temperature, and then the solvent From temperatures above the boiling point
The active ingredients distilled at temperatures up to 120°C or 130°C were collected. The results are shown in Table 1. Comparative Example 1 The mother liquor was produced according to the same recipe as in Example 2, but the fractional distillation temperature in the secondary treatment of the mother liquor was increased to 150° C., and 490 g of distilled components were collected.

【table】

[Table] Study Example 1 Using each of the deodorizing and deodorizing materials obtained in this manner, the occurrence of off-odor was compared and studied. The equipment used for this experiment was a 500ml liquid tank, and for Examples 1 and 3, the sampled deodorizer,
Add 200 ml of deodorizing material diluted to 450 ml with water, and for the mother liquor of Example 2, Comparative Example 1, and Example 2 (hereinafter referred to as Comparative Example 2),
Pour 450 ml of each of these directly, and for Examples 4 and 5, add 20 g of the collected deodorizing and deodorizing material to 450 ml of 10% propylene glycol.
I diluted it so that it was. A braided hydrophilic glass mat is inserted into each liquid material tank so that the liquid in the tank can be sucked up, and the temperature of the glass mat part is approximately 200℃. A heater was installed to adjust the temperature to maintain the temperature at ℃, and the odor of the odor and deodorizing material forcibly evaporated from the glass mat by heating was sequentially observed. Table 2 shows the measurement results of the amount of residual soot.

[Table] In this way, the present invention was carried out when a deodorizing and deodorizing device was used to forcibly evaporate the deodorizing and deodorizing material containing plant components with a small amount of non-volatile residue by heating. In all cases, there was no off-odor from the evaporated substances until 3 days later, and some gave off a slight off-odor after 5 days. However, the amount was so small that it hardly caused a problem in practical use. On the other hand, in Comparative Examples 1 and 2, 1
After some time, they were all already emitting a slight odor. In both cases, the odor becomes stronger as time passes, but this odor is like burnt tea and is very unpleasant to the nose. After 7 days, the deodorizing and deodorizing materials according to the present invention have completely evaporated the liquid and have very little residue, but those of Comparative Examples 1 and 2 have a large amount of residue. The amount of residue was compared with that of Example 2, where the only difference was that the distillation temperature during the secondary treatment was up to 130°C and up to 150°C, and the other conditions were exactly the same. When compared with Example 1,
The amount of residue is 0.3 g and 25.8 g, which is a large difference of 86 times even by simple calculation, which shows how effective the present invention is. Moreover, in Comparative Example 2, in which secondary treatment was not performed, a large amount of brownish substance was stuck to the glass mat, and a strange odor was generated from this, and furthermore, the liquid material in the tank was no longer being sucked up. It was in a state where there was no. Study Example 2 Further, the deodorizing and deodorizing properties of the deodorizing and deodorizing materials collected in Examples 1 and 2 and Comparative Examples 1 and 2 were investigated. To do this, inject ammonia gas into a 500 ml flask to a concentration of 200 ppm, quickly fill it with 3 ml of each deodorizing agent, and measure the remaining ammonia concentration in the flask after 10 minutes using a Kitagawa detection tube. The ammonia concentration in all cases was below the detection limit, which indicates that the deodorizing and deodorizing performance of the deodorizing material of the present invention is comparable to that of conventional materials that are not subjected to distillation treatment. It turns out that. Separately, in Example 2, the liquid material to be distilled at a temperature range of 120°C to 150°C was collected, and the concentration of residual ammonia gas was examined using this material according to the above procedure. , its concentration was 10 ppm. Incidentally, when the residual ammonia gas concentration was also investigated in a blank experiment using distilled water, it was 12 ppm. These results indicate that the distilled deodorizing and deodorizing material of the present invention has excellent deodorizing and deodorizing properties. Since the properties are not very good, most of the ingredients that are truly effective as deodorizing and deodorizing materials are contained in the fraction distilled within the temperature range of the present invention, and the fraction distilled at a temperature higher than that is substantially deodorizing. It can be said that it does not work very effectively as a deodorizing material, as it does not emit any strange odor when trying to forcefully evaporate it by heating the deodorizing material.
The mother liquor extracted from the leaves of evergreen broad-leaved trees is extracted under atmospheric pressure.
The fact that the active ingredients were distilled at a temperature of 130 degrees Celsius coincidentally means that the ingredients effective in deodorizing and deodorizing properties are separated and extracted from the mother liquor extracted from the leaves of plants such as evergreen broad-leaved trees. What it means is interesting.
