Description

Detailed Description of the Invention (Field of Technology) The present invention is characterized in that it contains a neutral oil obtained by separating and refining a plant essential oil such as Hiba oil collected from Hiba, Cypress, etc. Related to aroma purifiers.

(Prior Art) Wood such as cypress and cypress has a strong aroma, is glossy, and is strong, so they are widely used as construction materials and other materials. However, it is difficult to maintain the same aroma and luster as new wood for a long period of time.

Conventionally, when Hiba or Hinoki wood is used as a building material, it is dry wiped. It was removed by methods such as polishing with a rice bran bag.

A method for purifying hinokitiol from plant essential oil such as Hiba is described in, for example, Pharmaceutical Journal (64,181-185゜194
4) and the patent publication (Japanese Patent Publication No. 33-8518).

The former is a method in which hinokitiol-containing plant essential oil is reacted with an alkali such as caustic soda, and separated and purified as crystals of alkali hinokitiolate.The latter is a method in which acidic oil is separated from hinokitiol-containing plant essential oil by alkaline extraction, and the acidic oil is purified. After removing the acid with bicarbonate of soda, convert the residual oil into a monovalent metal salt, add a divalent metal salt or a divalent or higher valent metal salt to the solution, leave it to stand, and wash the resulting precipitate with warm water. Cover the remaining metal complex with petroleum ether and add excess dilute hydrochloric acid while stirring well to transfer hinokitiol to petroleum ether, then drive off the petroleum ether and distill the residue, or dissolve the complex salt with caustic soda. Hinokitiol is obtained by passing through sodium salt.

(Problems to be Solved by the Invention) As mentioned above, it is known that hiba oil collected from cypress, cypress, etc. contains hinokitiol; The inventors of the present invention conducted research based on the idea that these aromatic components may contain active ingredients that can be used for some purpose. , which led to the completion of this invention.

Most of the active ingredients, including aromatic ingredients, are contained in the neutral oil component of the cypress oil component, and hinokitiol is contained in the acidic oil component. Therefore.

First, it is important to separate cypress oil into neutral oil and acidic oil, but the above-mentioned literature only briefly describes that acidic oil is obtained by reacting with an alkali.

In view of the above, the inventors of the present application have proposed a simple method for separating cypress oil into acidic oil and neutral oil, and in particular, a method for fractionating the neutral oil without impairing its aromatic properties. Patent application (
Although it was clarified in A), the present invention clarifies the effectiveness and uses of the obtained neutral oil.

(Structure of the invention) A. Separation and purification of neutral oil and acidic oil. Crushed leaves, wood, and roots of cypress and cypress plants, or sawdust produced during felling or sawing of cypress wood, cypress wood, etc. To the distillate obtained by steam distilling or dry distilling, for example, an alkaline solution such as 10% aOH is added and steam distilled. The distilled fraction obtained by this is composed of neutral oil and water, and #-type oil is contained in the distillation residue. According to the separation method of the present invention, it is extremely simple compared to conventional methods can be separated into neutral oil and acidic oil.

If the obtained neutral oil is further separated from water by, for example, placing it in a freezer to freeze the water, a refined neutral oil can be obtained.

Next, by further distilling the neutral oil obtained above, it can be fractionated, for example, as follows.

a. Strong aroma, smooth oil, and does not solidify even at low temperatures.

b. The aroma is dilute, the oil is viscous, and does not solidify even at low temperatures.

C1 Has no odor, has high viscosity, and solidifies at low temperatures.

The neutral oil separated and purified as described above has a rich aroma and can be used for various purposes such as insect repellent, aromatic adhesive, aromatic cleaning agent, etc. as detailed below. be.

B. Separation test example Crude cypress oil obtained by carbonizing sawdust of cypress wood 100
0g and 10% NaOH solution 5001 were added and mixed, water vapor was introduced into this, 5000ml of distillate was taken, this was placed in a freezer, and freeze separation from water was repeated to obtain purified neutral oil eoog. (As mentioned above, this neutral oil component is further divided into groups with different properties by fractional distillation.)
11 is possible. ) Also, an alkaline layer is separated from the steam distillation residue (acidic oil), washed with petroleum ether, and the alkaline portion is
The pH was adjusted to 4 by adding Cl, and the precipitated oil was extracted with petroleum ether, which was then poured into a tower filled with alumina to be adsorbed, washed twice with the same amount of petroleum ether, and then washed with alcohol. The eluate obtained was concentrated to obtain 10 g of hinokitiol with a mp of 50°C.

C2 Efficacy Test (a) Aromaticity Rich aromaticity, especially neutral oil at 90°C to 110°C
Those distilled and fractionated within the range of 0.1
Even when the concentration was diluted to 10% to 10%, sufficient aromatic properties were maintained.

(b) Solubility of substances The amount of neutral oil required to dissolve a certain substance was tested for many substances, and it was verified that it had high substance solubility.

(C) Insect repellency A comparison was made between a piece of wood impregnated with the purified neutral oil diluted with alcohol and a piece of wood that was not impregnated with anything. In a comparative experiment, both pieces of wood were placed in the same dish with a certain distance apart, and dozens of ants were released.The ants did not approach the piece of wood impregnated with neutral oil, and after a few minutes, Since all the ants were killed, it was proven that this neutral oil contains ingredients that have insect repellent, insect repellent, and insecticidal effects.

(d) Antibacterial When the antibacterial effect of the neutral oil was investigated at different concentrations against fungi such as Staphylococcus, Escherichia coli, Bacillus subtilis, and Aspergillus flavus, significant antibacterial activity was verified.

D. Application (a) Cleaning agent Add purified neutral oil to alcohol, petroleum ether, kerosene, etc.
A cleaning agent was prepared by dissolving the solution at a concentration of 1% to 10% and spraying or coating it on a dry cloth.

If you wipe wooden pillars, furniture, etc. with a cloth coated with this cleaning agent, the surface will be cleaned and a glossy effect will be obtained, and
It also emits a fragrance.

Furthermore, since it has an insect repellent effect, it is possible to prevent the pillars from being eaten by insects. Note that this cleaning agent may be directly sprayed or applied.

(b) Fragrance Refined neutral oil to 1% alconyl petroleum ether, kerosene, etc.
A pressurized container was filled with the solution dissolved at a concentration of 1% to 10%, and a fluorocarbon gas or the like was added thereto and the container was sealed to produce a spray fragrance.

By spraying an appropriate amount of this atomized air freshener indoors, it is possible not only to obtain a fresh taste similar to when the room was newly built, but also to obtain an insect repellent effect by spraying it in a closet or the like.

Moreover, this method for producing a spray fragrance can be utilized when producing the above-mentioned cleaning agent.

(C) Adhesive: 100 g of a woodworking pound is mixed with neutral oil Log, and wood is bonded using a commonly used wood bonding method.

The adhesion effect is as good as when using only pounds, and it releases a fragrance for a long period of time, so it is useful when used in the manufacture of furniture, etc.

(d) Others The neutral oil refining agent of the present invention has uses other than those mentioned above.

For example, it can be used for various purposes, such as a spray fragrance substitute for forest bathing.

(Effects of the Invention) Since this invention is configured as described above, it can easily achieve the above-mentioned purpose, and as explained in the section on effectiveness and use, it has many efficiencies. and can be used for beneficial purposes.
