Abstract
The device of manganese dioxide catalytic decomposition hydrogen peroxide oxygen producing, comprise trestle table, spherical hopper is fixed on the upper iron ring of trestle table, spherical hopper upper end conduit stretches in back-off gas bottle in the sink, two conduits that spherical hopper end opening connects, under a conduit stretches into and is fixed on trestle table, iron ring is contained in the end opening of hydrogen peroxide cartridge, and another root extend in the container be filled with water with the conduit of tongs, the opened upper end of described Sheng hydrogen peroxide cartridge.Waste liquid bleeds off by the tongs can opening long neck funnel lower end in the utility model experiment at any time, ensureing that the concentration of hydrogen peroxide can not be too rare, saving time for comparatively fast producing one bottle of oxygen; It is a bit of that the conduit stretched in long neck funnel be connected with beverage bottle stretches out liquid level, and when preventing from opening tongs radioactive waste liquid, part waste liquid flows in the conduit connecting beverage bottle; Using also can very fast oxygen producing compared with the superoxol of small concentration, saving medicine.
Description
Technical field
The utility model relates to a kind of device of manganese dioxide catalytic decomposition hydrogen peroxide oxygen producing.
Background technology
At present, a lot of to the experiment Innovatation of peroxide decomposition oxygen producing in junior middle school chemistry textbook, mainly for the generation that can not immediately control in experimentation to react and stopping, only having added H
2o
2after decomposing completely, reaction could stop; After also having research to terminate for reaction, as the MnO of catalyzer
2be not easy to instant recycling, solid and liquid drug are wasted serious problem and are improved, by MnO
2make solid particle by a certain percentage with cement, also adopt the simple and easy equipment of the life-stylizes such as beverage bottle, but this improvement is more applicable for the hydrogen peroxide oxygen producing that concentration is larger, if when hydrogen peroxide concentration is about 5%, effect is unsatisfactory.Because in course of reaction, the concentration of superoxol is more and more less, cause and cannot collect full one bottle of oxygen for its Property Verification.
Summary of the invention
The purpose of this utility model is to provide a kind of device and using method of manganese dioxide catalytic decomposition hydrogen peroxide oxygen producing, when making hydrogen peroxide concentration be about 5%, also comparatively fast can collect full bottle oxygen.
For achieving the above object, the utility model is by the following technical solutions:
The device of manganese dioxide catalytic decomposition hydrogen peroxide oxygen producing, comprise trestle table, spherical hopper is fixed on the upper iron ring of trestle table, the conduit of spherical hopper connection suitable for reading stretches in back-off gas bottle in the sink, two conduits that spherical hopper end opening connects, under a conduit stretches into and is fixed on trestle table, iron ring is contained in the end opening of hydrogen peroxide cartridge, and another root extend in the container be filled with water with the conduit of tongs, the opened upper end of described Sheng hydrogen peroxide cartridge.
The end opening of described spherical hopper and the end opening place of Sheng hydrogen peroxide cartridge are provided with rubber plug.
Butterfly fastening bolt is provided with between described iron ring and the pole of trestle table.
The container of described Sheng hydrogen peroxide is beverage bottle.
The utility model can reach following advantage: waste liquid bleeds off by the tongs can opening long neck funnel lower end in experiment at any time, ensureing that the concentration of hydrogen peroxide can not be too rare, saving time for comparatively fast producing one bottle of oxygen; Use waste and old beverage bottle as experiment equipment in experiment, embody the life-stylize of experiment; It is a bit of that the conduit stretched in long neck funnel be connected with beverage bottle stretches out liquid level, and when preventing from opening tongs radioactive waste liquid, part waste liquid flows in the conduit connecting beverage bottle; Using also can very fast oxygen producing compared with the superoxol of small concentration, saving medicine.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, the device of manganese dioxide catalytic decomposition hydrogen peroxide oxygen producing, comprise trestle table 13, spherical hopper is fixed on the upper iron ring of trestle table, the conduit that spherical hopper 9 upper end connects stretches in the gas bottle 10 tipped upside down in tank 11, two conduits that spherical hopper end opening connects, under a conduit 5 stretches into and is fixed on trestle table, iron ring 4 is contained in the end opening of hydrogen peroxide cartridge 3, another root extend in the container 6 be filled with water with the conduit 8 of tongs 7, the opened upper end of described Sheng hydrogen peroxide cartridge.The end opening of described spherical hopper and the end opening place of Sheng hydrogen peroxide cartridge are provided with rubber plug 12.Butterfly fastening bolt 2 is provided with between the pole 1 of described iron ring and trestle table.The container 3 of described Sheng hydrogen peroxide is waste and old beverage bottle.
Using method step of the present utility model is as follows: step one, the bubble-tight inspection of device, water is added in the container 3 of opened upper end, the tube at one end connecting spherical hopper top is stretched in the tank 11 be filled with water, promote the height containing hydrogen peroxide cartridge 3, if conduit mouth produces bubble, then device is air tight;
Step 2, loads medicine, first in spherical hopper 9, puts into block manganese dioxide, then adds aqueous hydrogen peroxide solution, retainer instrument in the container 3 of Sheng hydrogen peroxide;
Step 3, starts reaction, collects oxygen.Promote the height containing hydrogen peroxide cartridge 3, superoxol is contacted with block manganese dioxide, reaction occurs; When conduit mouth occur continuously, uniform bubble time start to collect; If bubble reduces, waste liquid is put in the container be filled with water by the tongs 7 opening spherical hopper 9 lower end, promote the height of beverage bottle again, aqueous hydrogen peroxide solution is contacted with block manganese dioxide again, this process just can collect full one bottle of oxygen very soon repeatedly, after collecting full gas, make Separation of Solid and Liquid, stop reaction.
Step 4, is oxygen with the gas that the batten checking of band Mars is collected, and can be used for other Property Verification of oxygen.
