Abstract
The utility model discloses a kind of experimental provision for producing ammonia, it is characterised in that：Including iron stand, iron ring, iron clamp, alcolhol burner, evaporating dish, glass funnel, glass tube, rubber tube, rubber stopper, test tube and absorbent cotton, the evaporating dish is fixed on iron stand by iron ring, alcolhol burner is placed under evaporating dish to be used to heat, the glass funnel back-off is in evaporating dish, the glass tube is connected by rubber tube with glass funnel one end, the glass tube is fixed on iron stand by iron clamp and rubber stopper, and the test tube back-off fills absorbent cotton on glass tube, and in test tube mouth.The experimental provision has materials easy, and installation is simple, and easily operated, positive effect a little, and can solve the problems, such as test tube badly broken during product in laboratory ammonia, reduces experiment spending, is advantageous to the initiative spirit and economy consciousness of training student.
Description
Technical field
It the utility model is related to chemistry teaching demonstration teaching aid technical field, and in particular to a kind of experimental provision for producing ammonia
Background technology
Chemical experiment is the important method that student understands, studied the natural law, is the basis of whole chemistry teaching, is culture
Students ' practical ability operates and the main path of thinking ability, is also to aid in student and understands chemical basic conception and general principle
Effective means, even more quality-oriented education and innovative education forward position and basic educational reform basis and guarantee.
It is well known that the experiment of product in laboratory ammonia is an important Demonstrating and student experimenting.However,
In teaching practice, when produce the experiment of ammonia according to the experimental provision and experimental method provided on textbook, although can
So that ammonia is made, but due to being equipped with the mixture of slaked lime powder and ammonium chloride in teat glass, calcium hydroxide is easy when heating test tube
Reacted with glass in test tube, cause test tube to burst.According to statistics, the test tube breakage rate of the experiment is up to more than 95%, especially
When being student experimenting, test tube loss is even more serious, and so as to increase experiment spending, unnecessary economic damage is caused to school
Lose.
The content of the invention
The purpose of this utility model is to be directed to deficiency of the prior art, there is provided a kind of experimental provision for producing ammonia.Should
A kind of experimental provision for producing ammonia has materials easy, and installation is simple, easily operated, the advantages of positive effect.
The purpose of this utility model is realized by following technological means：A kind of experimental provision for producing ammonia, it is special
Sign is：Including iron stand, iron ring, iron clamp, alcolhol burner, evaporating dish, glass funnel, glass tube, rubber tube, rubber stopper, test tube
Place alcolhol burner and absorbent cotton, the evaporating dish are fixed on iron stand by iron ring, under evaporating dish to be used to heat, the glass
Funnel back-off is connected in evaporating dish, the glass tube by rubber tube with glass funnel one end, and the glass tube passes through iron clamp
It is fixed on rubber stopper on iron stand, the test tube back-off fills absorbent cotton on glass tube, and in test tube mouth.
Preferably, a certain amount of ammonium chloride and slaked lime powder are placed in the evaporating dish.
Compared with prior art, the utility model has advantages below：Equipment materials used are easy in the device, installation letter
It is single, easily operated, positive effect, can also solve the problems, such as test tube badly broken during product in laboratory ammonia, reduce experiment
Spending, be advantageous to the initiative spirit and economy consciousness of training student.
Brief description of the drawings
Fig. 1 produces the structural representation of the experimental provision of ammonia.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete

Structural representation of the present utility model as shown in Figure 1, a kind of experimental provision for producing ammonia, its feature exist
In：Including iron stand 1, iron ring 2, iron clamp 3, alcolhol burner 4, evaporating dish 5, glass funnel 6, glass tube 7, rubber tube 8, rubber stopper 9,
Test tube 10 and absorbent cotton 11, the evaporating dish 5 are fixed on iron stand 1 by iron ring 2, and 5 times placement alcolhol burners 4 of evaporating dish are used for
Heating, the back-off of glass funnel 6 are connected in evaporating dish 5, the glass tube 7 by rubber tube 8 with the one end of glass funnel 6,
The glass tube 7 is fixed on iron stand 1 by iron clamp 3 and rubber stopper 9, and the back-off of test tube 10 is being tried on glass tube 7
The mouth of pipe fills absorbent cotton 11.
A certain amount of ammonium chloride and slaked lime powder are placed in evaporating dish 5, cake contacts in evaporating dish 5 with glass funnel 6
Gap is covered, is compacted by position with thin slaked lime powder, is escaped to prevent ammonia.Light alcolhol burner, the ammonium chloride in heating evaporation ware
With the mixture of calcium hydroxide.For a moment, you can full ammonia is collected in dry test tube 10.
In a word, the utility model provides a kind of experimental provision for producing ammonia.It is described above, it is only of the present utility model
A part of embodiment, the scope of protection of the utility model are not limited thereto, any technology for being familiar with the art
Personnel are in the technical scope that the utility model discloses, and the change or replacement that can readily occur in should all be covered in the utility model
Protection domain within.
