- the present invention relates to an oxygen clathrate hydrate and an oxygen solution containing the same.
- the present applicant has proposed a technique for mixing, dissolving, and subdividing liquid phase, gas phase, and solid phase materials with respect to a fluid such as water.
- a fluid such as water.
- oxygen water with the feature that the state of dissolved oxygen amount of 25 ppm or more persists for 35 days or more even in an open atmosphere is produced. can do.
- the oxygen-rich water which is commercially available conventionally, be oxygen water comparable produced by the existing of dissolved oxygen measured by the measurement method gas-liquid mixing device of Patent Document 1, the value of the SpO 2 by drinking It has also been confirmed that no increase is observed.
- the present inventors succeeded in producing a completely new oxygen solution by a new production method improved from the conventional method. And while intensively researching the properties of this new oxygen solution using the newly established method for measuring dissolved oxygen, this new oxygen solution is released into the atmosphere even when heated. The present inventors have found that a large amount of dissolved oxygen dissolved without being contained.
- the present invention provides the following dissolved oxygen and oxygen solution.
- the amount of dissolved oxygen is The following steps: (1) adding a deoxygenating amino compound to an oxygen solution and heating at a temperature of 80 ° C.
- a step of measuring the concentration of the deoxygenating amino compound contained in the oxygen solution a step of measuring the concentration of the deoxygenating amino compound contained in the oxygen solution
- the dissolved oxygen amount (ppm) measured by the dissolved oxygen amount measuring method including the oxygen dissolved solution measured by any one of the diaphragm method, the fluorescence method and the Winkler method.
- the oxygen-dissolved solution according to ⁇ 1> which is obtained by a difference (P1 ⁇ P2) between a dissolved oxygen amount (ppm) and a numerical value P2.
- ⁇ 5> The following steps: (1) adding a deoxygenating amino compound to an oxygen solution and heating at a temperature of 80 ° C. or higher; (2) After the step (1), a step of measuring the concentration of the deoxygenating amino compound contained in the oxygen solution; (3) A step of calculating the amount of dissolved oxygen contained in the oxygen solution before passing through the step (1) from the concentration of the deoxygenated amino compound measured in the step (2); Of the dissolved oxygen amount (ppm) measured by the dissolved oxygen amount measuring method including the oxygen dissolved solution measured by any one of the diaphragm method, the fluorescence method and the Winkler method.
- An oxygen-dissolved solution characterized in that the amount of dissolved oxygen obtained by the difference (P1-P2) of the dissolved oxygen content (ppm) from the numerical value P2 is 50 ppm or more.
- the gas-liquid mixing pump of the present invention is a gas-liquid mixing pump for producing the oxygen solution, and includes a hollow housing having a substantially disk-shaped outer shape and a rotor housed in the center of the housing.
- the housing includes a plurality of partition walls extending from the outer edge portion toward the vicinity of the center, the rotor includes a plurality of rotor blades protruding in a rib shape, and water containing gas is supplied into the housing and the rotor is provided.
- water containing gas is supplied toward the outer edge of the housing by the pressure of the rotor blades, and the gas is dissolved in water by supervibration.
- the oxygen-dissolved solution of the present invention contains a large amount of dissolved oxygen (oxygen clathrate hydrate) that cannot be measured by the conventional measurement method and is maintained in a dissolved state without being released into the atmosphere even when heated. ing.
- FIG. 1 It is the schematic which illustrated one Embodiment of the oxygen solution manufacturing system. It is the figure which illustrated one Embodiment of the gas-liquid mixing pump contained in the oxygen solution manufacturing system illustrated in FIG. It is an internal perspective view which illustrated one embodiment of the gas-liquid separation device contained in an oxygen solution production system. It is a figure which shows the result of having measured the oxygen amount of the oxygen solution before a heating and after a heating. It is a photograph which shows the growth condition of the sweet basil of the 3rd day after cultivation and the 9th day. It is a photograph which shows the growth condition of sweet basil on the 15th day and 24th day after cultivation. It is a photograph which shows the growth condition of the sweet basil on the 24th day after cultivation. It is a photograph which shows the growth condition of the sweet basil on the 34th day after cultivation.
- the inventors of the present invention have improved the conventional production apparatus to include an oxygen clathrate hydrate containing dissolved oxygen that remains dissolved in a solution even when heated to 100 ° C.
- ice containing oxygen can be obtained by freezing the oxygen solution, and this ice also contains oxygen in a stable state.
- the dissolved oxygen contained in the oxygen solution of the present invention is considered to be dissolved in the state of oxygen clathrate hydrate formed by oxygen molecules and water molecules.
- oxygen clathrate hydrate is a compound in a form in which oxygen molecules are surrounded by a lattice of water molecules.
- the oxygen clathrate hydrate contained in the oxygen-dissolved solution of the present invention can be measured by measuring the dissolved oxygen in conventional methods for measuring the amount of dissolved oxygen such as the diaphragm electrode method, the Winkler method, and the fluorescence method. However, the amount of dissolved oxygen is measured by the dissolved oxygen content measuring method newly established by the present inventors.
- the oxygen clathrate hydrate of the present invention is considered to be completely different from the conventional oxygen water in the molecular bonding state and energy state.
- dissolved oxygen that remains dissolved in the solution even when heated to 100 ° C. contained in the oxygen-dissolved solution of the present invention is determined by the following dissolved oxygen content measuring method devised by the present inventors. Can be measured.
- This method for measuring the amount of dissolved oxygen is a method for measuring the amount of dissolved oxygen contained in a liquid sample, and includes the following steps: (1) A step of adding a deoxygenated amino compound to a liquid sample to prepare a predetermined concentration; (2) After the step (1), a step of heating a liquid sample containing a deoxygenated amino compound at a temperature of 80 ° C. or higher; (3) After the step (2), a step of measuring the concentration of the deoxygenated amino compound contained in the liquid sample; (4) The concentration of the deoxygenated amino compound measured in the step (3) is compared with the concentration of the deoxygenated amino compound in the step (1).

- carbohydrazide is conventionally used as an oxygen scavenger for plants, boilers and the like as described in Patent Document 2 and the like. In plants and boilers, if a small amount of oxygen is contained in the supplied water, etc., it may cause corrosion of metal equipment, etc., so oxygen is chemically removed by deoxygenating amino compounds such as carbohydrazide.

- step (3) after the step (2), the concentration of the deoxygenated amino compound contained in the liquid sample is measured.
- the method for measuring the concentration of the deoxygenating amino compound is not particularly limited, and a known method such as an iodine titration method (oxidation-reduction titration method) can be appropriately employed.

This indicates that 50 ppm or more of oxygen clathrate hydrate is dissolved.
- oxygen clathrate hydrate formed by oxygen molecules and water molecules will be described more specifically, taking as an example a form using carbohydrazide as the deoxygenating amino compound.
- dissolved oxygen that remains dissolved in the solution even when heated to 100 ° C.” contained in the oxygen-dissolved water of the present invention can be measured by the following procedure.
- A About the oxygen solution to measure, dissolved oxygen amount P2 (ppm) is measured by the dissolved oxygen amount measuring methods, such as the conventional diaphragm method.
- B Carbohydrazide is added to the oxygen solution at room temperature so that the concentration becomes 0.01 to 2%.
