Abstract
An apparatus for experimenting and demonstrating the properties of carbon monoxide relates to an improvement of the structure of the experiment and demonstration apparatus, which can help understand the preparation method of carbon monoxide and can be safely used. The apparatus comprises a generator, a filter, a reduction reaction unit and a recovery unit which are sequentially connected together through gas tubes. The structure of the apparatus has the following characteristics: the generator is a florence flask provided with a separating funnel and a rubber cork; both the filter and the recovery unit are wide-mouth bottles provided with rubber corks; and the reduction reaction unit is a glass tube, both ends of which are provided with rubber corks.
Description
Technical field:
The utility model relates to the improvement of experimental demonstration device structure.
Background technology:
In middle school chemistry study, through experiment aided education commonly used.Can strengthen the student to the understanding of carbon monoxide character and can enhance memory to the lecture experiment of carbon monoxide character.At present provide carbon monoxide to carry out lecture experiment with the carbon monoxide gas storage device, in case gas storage device leaks, perhaps connection procedure is made a fault, and a large amount of carbon monoxide leak operating personnel are poisoned; Because misoperation can also be blasted, and very big potential safety hazard is arranged.Use the carbon monoxide gas storage device, the student can not obtain visual understanding to the preparation method of carbon monoxide.
The utility model content:
The utility model is exactly at the problems referred to above, provides a kind of preparation method method that helps to understand carbon monoxide, the demonstrating experiment device of carbon monoxide character safe in utilization.
For achieving the above object, the utility model adopts following technical scheme, the utility model comprises generating means, filtration unit, reduction reaction device and the retracting device that links to each other successively by wireway, and its structural feature is that generating means is the flat bottom flask that is provided with separating funnel and rubber stopper; Filtration unit and retracting device all are the wide-necked bottles that are provided with rubber stopper; The reduction reaction device is the glass tube that two ends are provided with rubber stopper.
The beneficial effects of the utility model:
It is the flat bottom flask that is provided with separating funnel and rubber stopper that the utility model adopts generating means; Filtration unit and retracting device all are the wide-necked bottles that are provided with rubber stopper; The reduction reaction device is the glass tube that two ends are provided with rubber stopper; Can allow the student understand the preparation method of carbon monoxide by experiment; Understand the reductibility and the reaction product of carbon monoxide simultaneously.Whole device uses the rubber stopper sealing, and the carbon monoxide preparation amount is few, and is safe in utilization.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Embodiment:
The utility model comprises generating means 1, filtration unit 2, reduction reaction device 3 and the retracting device 4 that links to each other successively by wireway 9, and generating means 1 is the flat bottom flask 7 that is provided with separating funnel 5 and rubber stopper 6; Filtration unit 2 and retracting device 4 all are the wide-necked bottles 10 that are provided with rubber stopper 6; Reduction reaction device 3 is glass tubes 8 that two ends are provided with rubber stopper 6.
When doing lecture experiment, first with the concentrated sulphuric acid of packing in the flat bottom flask 7, the formic acid of packing in the separating funnel 5, the clarification lime water of packing into an amount of in the wide-necked bottle 10, the cupric oxide of packing in the glass tube 8 also is fixed on the iron stand 11, and the spirit lamp of lighting in glass tube 8 underneath 12; Then, the valve 13 of opening separating funnel 5 allows formic acid flow into flat bottom flask 7, and carbon monoxide and carbon dioxide that reaction produces enter filtration unit 2 through wireway 9, filter out carbon dioxide, and it is muddy that the clarification lime water in the wide-necked bottle 10 becomes; Carbon monoxide enters the glass tube 8 of reduction reaction device 3 by wireway 9, and the cupric oxide of black is reddened, and the carbon dioxide of generation enters the wide-necked bottle 10 of retracting device 4 by wireway 9, makes clarification lime water become muddy.
