Problems solved by technology

However, the stability of ozone is poor. The half-life of ozone in distilled water or tap water is about 20 minutes (20°C), and it quickly decomposes into oxygen in aqueous solution containing impurities.
Therefore, in actual use, ozone often needs to be prepared immediately, which is greatly limited by equipment and sites, which greatly limits the application of ozone

preparation example Construction

[0039] The preparation method of the described a kind of ozonated water emulsion is characterized in that, the described ozonated organic matter is emulsified in water, the continuous phase after emulsification is water, the dispersed phase is oil, and the average particle diameter of dispersed phase oil droplets is less than 100 μm. In actual use, the particle size of emulsified oil droplets can be adjusted according to needs, but care should be taken to avoid the coalescence of oil droplets and the phenomenon of oil-water phase.

[0040] During the preparation of the ozonated water emulsion, improvers such as fragrances, dyes, and liquid paraffin can be added to the system as needed to improve the application performance and effect of the ozonated water emulsion. However, the amount of added components is generally less than 50% of the amount of ozonated organic matter added, and unacceptable effects on ozonated organic matter and ozonated water emulsion should be avoided. ...

Embodiment 1

[0043] Use a low-pressure pure water electric oxidation ozone generator to generate high-concentration ozone gas (the ozone content is about 15%), collect the ozone gas and pass it into the 316L stainless steel containing a mixture of olive oil and palmitoleic acid (the volume ratio of the two is 1:1) In the bubbling reactor, the reaction is carried out under the condition of stirring and 20°C, and the ozonation degree of the organic matter is tested by sampling. When the ozonation degree is ≥ 20%, the ozone bubbling is stopped. According to the volume ratio of ozonated organic matter and water 1:100, the ozonated organic matter was mixed with pure water, and emulsified using a high-speed shearing machine. After emulsification, the particle size of the ozonated organic matter suspended in the continuous water phase was about 50 μm. Dilute the ozonated water emulsion 10 times, under the condition of airtight, glass container and 20 ℃, compared with the ozone pure aqueous solutio...

Embodiment 2

[0045] Use a pure water electro-oxidation ozonator to generate high-concentration ozone gas (the ozone content is about 20%), collect the ozone gas and pass it into a glass-lined pipe reactor filled with a mixture of C8 olefins and fish oil (the volume ratio of the two is 1:5) Inside, the reaction is carried out under the conditions of pipeline circulation mixing and stirring at 30°C, and the ozonation degree of organic matter is tested by sampling. When the ozonation degree reaches 30%, the ozone is stopped. According to the ratio of ozonated organic matter to pure water volume ratio of 1:50, use membrane emulsification equipment to emulsify ozonated organic matter in aqueous solution, add 100ppm sodium dodecylsulfonate to the emulsified liquid, and suspend in the continuous water phase after emulsification The particle size of ozonated organic matter is about 20 μm. Dilute the ozonated water emulsion 100 times, under the conditions of airtight, glass container and 20 ℃, comp...

Description

technical field [0001] The invention relates to a preparation method of an ozonated water emulsion, in particular to a method of firstly preparing an ozonated organic matter, and then emulsifying in water to obtain an ozonated water emulsion. Background technique [0002] Ozone (O 3 ), also known as superoxide, is oxygen (O 2 ) allotrope, at room temperature, it is a light blue gas with a special odor, and the product of decomposition is oxygen. Ozone is a strong oxidant, its oxidation-reduction potential in water is 2.07 eV, second only to fluorine (2.5 eV), and its oxidation capacity is higher than that of chlorine (1.36 eV) and chlorine dioxide (1.5 eV). Unlike hypochlorous acid disinfectants, the bactericidal ability of ozone is not affected by pH changes and ammonia, and its bactericidal ability is 600-3000 times greater than that of chlorine. Its sterilization and disinfection effects occur almost instantaneously. When the ozone concentration reaches 0.3-2 mg / L, bac...
