Abstract
The utility model discloses a three test tube method gas-solid reaction experiment device. The device aims to overcome problems that the conventional reaction device is poor in versatility, long in line, poor in airtightness, complex in operation and poor in tail gas processing. The device comprises a U-shaped glass tube, a first zone test tube, and a second zone test tube. The tube bodies at the two sides of the U-shaped glass tube are respectively a first zone and a second zone. The center of the U-shaped glass tube is a third zone. The first zone test tube and the second zone test tube are respectively disposed in the first zone and the second zone. The openings of the first zone and the second zone of the U-shaped glass tube are sealed by rubber plugs that are respectively equipped with a dropper and a safety balloon. The lower end of the dropper is in the first zone test tube. The device is high in versatility, simple in structure, environment-friendly, simple in operation, safe and reliable, and low in cost.
Description
Technical field
The utility model is a kind of gas-solid reaction device, is a kind of multi-usage three test tube method reaction units.
Background technology
The common gas-solid reaction device in current middle school is all generally gas generation from solid-phase reactant respectively in different reactors, and above device all exists some problems in use: 1. instrument assembling is more complicated is not easy to do illustrative test; 2. instrument versatility is not strong, and purposes is single; 3. leakproofness is poor, harmful to health.
Utility model content
The object of the utility model design is to provide a kind of three test tube method gas-solid reaction experimental provisions, and to solve, existing reaction unit versatility is poor, route is long, leakproofness is poor, the problem of complicated operation, vent gas treatment.
Technical solutions of the utility model are as follows: a kind of three test tube method gas-solid reaction experimental provisions, it comprises U-shaped glass tube, district's test tube, two district's test tubes, the body of U-shaped glass tube both sides is respectively the firstth district and Second Region, Wei 3rd district of U-shaped glass tube central authorities, one district's test tube, two district's test tubes are housed respectively in the firstth district and Second Region, the firstth district of U-shaped glass tube and the mouth of pipe of Second Region are all sealed with rubber stopper, are inserted with respectively dropper and safe balloon in rubber stopper, and the lower end of dropper is arranged in district's test tube.
The utility model is the integrated experimental device that a kind of easy gas generation and solid-phase reactant react, simple in structure, and environmental protection is easy and simple to handle, highly versatile, and good leak tightness, safe and reliable, cost is low.Can complete the gas-solid reaction experiment (experiment of chlorine and copper wire, iron wire, sodium metal, red phosphorus, copperoxide reduction with carbon monoxide, the experiment that iron wire burns in oxygen), can complete again gas generation and Property Verification experiment simultaneously, be suitable for chemical demonstrator experiment and student experimenting.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Reference numeral implication is as follows: safe balloon (1), two district's test tubes (2), dropper (3), rubber stopper (4), U-shaped glass tube (5), district's test tube (6), solid-phase reactant (7), the firstth district (A), Second Region (B), San district (C).
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
A kind of three test tube method gas-solid reaction experimental provisions, comprise U-shaped glass tube 5, district's test tube 6, two district's test tubes 2, the body of U-shaped glass tube 5 both sides is respectively the first district A and Second Region B, the central Wei tri-district C of U-shaped glass tube 5, one district's test tube 6 He Er district test tubes 2 are housed respectively in the first district A and Second Region B, the first district A of U-shaped glass tube 5 and the mouth of pipe of Second Region B are all sealed with rubber stopper 4, interior dropper 3 and the safe balloon 1 of being inserted with respectively of rubber stopper 4, and the lower end of dropper 3 is arranged in district's test tube 6.
The firstth district is gas generation district, and Second Region is tail gas uptake zone, and San district is solid-phase reactant rest area.For gas property confirmatory experiment, two district's test tubes 2 adopt the micro test tube that is added with correlated response reagent.Specific operation process is as follows:
1. solid-phase reactant 7 is put into U-shaped glass tube 3rd district, put into be equipped with tail gas absorption liquid Er district test tube 2(do not need tail gas absorb reaction can not install additional tail gas absorb test tube, safe balloon can play buffer action), with the rubber stopper sealing that safe balloon is installed.
2. reactant Yi district test tube 6 will be housed and pack U-shaped glass tube into, (after to be heated for the reaction of needs heating, putting into U-shaped glass tube).
3. first dropper 3 is inserted in rubber stopper 4, after absorption reaction liquid, be installed to together with rubber stopper on U-shaped glass tube.Treat that it is available dropper 3 dropwise reaction reagent that device installs.
4. some reaction needed heating solid-phase reactants, can select spirit lamp heating 3rd district, solid-phase reactant place.
5. for gas confirmatory experiment, useable glass pipe self-control micro test tube adds after the required reagent of gas confirmatory experiment in micro test tube, pack the Second Region of U-shaped glass tube into, for gas confirmatory experiment, 3 li of interpolation associated gas of district's test tube 6 and dropper are prepared reagent, describe in detail in table 1.This experiment reagent consumption is few, and phenomenon is obvious, adds tail gas absorption liquid after completion of the reaction with syringe.
