Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for producing an aqueous germanium solution, and more specifically to a method for producing an aqueous germanium solution which is harmless to the living body.

[0002]

2. Description of the Related Art An aqueous germanium solution has a very small cluster and therefore has good permeability to a living body, and the components contained therein are better absorbed by the living body. Further, germanium contained in the solution is said to increase the resistance of the living body to harmful bacteria by activating cells in the living body. However, conventionally, a simple and economical method for producing a germanium aqueous solution harmless to a living body has not been proposed, and therefore, as a means for administering germanium to a living body, high purity germanium is orally administered to humans and animals. Things have only been tried a bit. That is, water-insoluble germanium is dissolved and absorbed in gastric juice rich in acid. Although germanium dioxide is soluble in water under certain conditions, it cannot be administered to a living body because it contains harmful substances such as chlorine.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to provide a simple method for producing an aqueous germanium solution which is made harmless to living organisms by using germanium dioxide.

[0004]

In order to achieve the above-mentioned object, the manufacturing method according to the present invention comprises adding germanium dioxide, high-purity water or alkaline ionized water and an organic acid, and mixing them by heating. It is characterized in that a weakly acidic or weakly alkaline aqueous solution is obtained by neutralizing with an acid neutralizing agent. In the step of neutralizing with the acid neutralizer, a mixture of germanium dioxide and high-purity water or alkaline ionized water and an organic acid, high-purity water or alkaline ionized water and an acid neutralizer are added little by little. It is preferable to repeat the step of stirring while heating. When adding high-purity water or alkaline ionized water and organic acid to germanium dioxide and heating and mixing, high-purity water or alkaline ionized water is added to germanium dioxide and mixed by heating, and then the organic acid is added to this mixture. In addition, it is preferable to stir while heating.

The amount of high-purity water or alkaline ionized water and the amount of organic acid added to germanium dioxide are not particularly limited. If the amount of water or alkaline ionized water is large,
The concentration of germanium in the produced aqueous solution is low, and in the opposite case, the concentration is only high, and if the amount of organic acid to be added is large, the required amount of the acid neutralizer is large, and if it is small, the acid neutralizer There is only a few. As a standard for economical production, high-purity water or alkaline ionized water 20 to 30 is added to 1 part by weight of germanium dioxide.
It is preferable to use about 5 to 10 parts by weight of the organic acid, and the amount of the acid neutralizing agent required in this case is about 6 to 18 parts by weight, depending on the kind.

The organic acid to be used is not particularly limited, and acetic acid, citric acid, succinic acid, malic acid, lactic acid, tartaric acid and other commercially available ones can be used alone or in combination of two or more kinds. As the neutralizing agent, sodium bicarbonate, calcium carbonate, metallic soda such as soda tungstate, and other commercially available ones can be used alone or in combination of two or more kinds.

[0007]

According to the method for producing an aqueous solution of germanium according to the present invention, an aqueous solution of germanium dioxide is obtained by heating and mixing highly pure water or alkaline ionized water and organic acid into germanium dioxide. By neutralizing with a solvating agent, most of chlorine and other harmful substances in the aqueous solution are released into the atmosphere during the neutralization process, and a germanium aqueous solution harmless to living organisms is produced.

[0008]

The preferred embodiments of the manufacturing method according to the present invention will be described in detail below. In a glass container having a capacity of about 1000 ml or other suitable container, 1 g of germanium dioxide is added with 2-3 g of alkaline electrolytic ionized water, and gradually heated to facilitate the dissolution of germanium dioxide. When the temperature of this mixture is heated to about 40 ° C. or higher, 5 to 6 g of citric acid is added thereto, and the mixture is stirred with heating.

When the mixture of germanium dioxide, alkaline electrolyzed ionic water and citric acid reaches a temperature of about 60 ° C. or higher and becomes a cloudy aqueous solution, the heating is stopped, and the aqueous solution is mixed with alkaline electrolyzed ionic water in an amount of 1 to 3 g. Add baking soda and stir. At this time, the temperature of the mixture is 80
It is preferable to stir while heating so that the temperature does not exceed ℃.

As mentioned above, when baking soda is added and stirred, foaming occurs, and the foaming gradually decreases. With less foam,
Again, about 1 g of baking soda is added with 2-3 g of alkaline electrolyzed water, and the mixture is stirred. Then, in a similar manner, the addition of alkaline electrolyzed ion water and baking soda and heating and stirring are repeated about 10 times as a whole, and finally when no foaming occurs,
A weakly acidic or weakly alkaline aqueous solution of germanium ion having a high transparency of about 20 to 30 ml is produced, with little residual amount of impurities such as chlorine or so small as to be harmless to the living body.

The germanium aqueous solution produced as described above is weakly acidic, and in order to make it into a weakly alkaline germanium aqueous solution, baking soda is added to the germanium aqueous solution together with a small amount of alkaline electrolyzed water and heated. While stirring, this is repeated until the pH of the aqueous solution reaches about 8.

The weakly acidic or weakly alkaline germanium aqueous solution produced as described above has much higher transparency than tap water, is harmless when administered to a living body, and has extremely high absorbability or penetrability into the living body. ..

In the above-mentioned embodiment, in the step of neutralizing with the acid neutralizing agent, the acid neutralizing agent and the alkaline electrolytic ionic water were added little by little and the mixture was heated and stirred repeatedly. If the disinfectant is an effervescent one and it is to accelerate neutralization, and if an acid neutralizer that does not foam in the liquid is used or if it is not necessary to complete the neutralization in a short time. Alternatively, the entire amount of acid neutralizer may be added and allowed to stand.

When high-purity water such as distilled water is used instead of the alkaline ionized water, the amount of the acid neutralizing agent used is slightly increased.

The method for producing a germanium aqueous solution according to the present invention is not limited to the above-mentioned embodiment, and other steps may be added or minor portions may be changed within the scope of the claims. It also includes the case of performing replacement.

[0016]

According to the production method of the present invention, it is possible to easily and economically produce a germanium aqueous solution which is harmless when administered to a living body and is useful for the living body.
