Abstract
The utility model relates to a catalysis demonstrator, which comprises a principal part. Wherein, the principal part is a 200mm is multiplied by 30mm hard-processing test tube (1) with a 25 degree to 35 degree bend in the place 40mm to 60mm far from the principal part bottom and a 10mm to 15mm convex part in the place 90mm to 110mm far from the tube opening. The utility model demonstrates catalysis of catalyst. During operation, the catalyst and other reactants are heated to observe reaction and temperature variation from (6). And then, the heated catalyst is poured into other reactants to observe reaction from (6) and understand catalysis of catalyst.
Description
Affiliated technical field
The utility model relates to a kind of catalytic action demonstration device.
Technical background
Textbook when speaking of the notion of catalytic action, lecture experiment designed three independently experiment combination finish, experimental period is long, causes teaching efficiency undesirable.
Summary of the invention
The purpose of this utility model is to provide a kind of catalytic action demonstration device, and this device can be merged into an experiment with three independent experiments and finish, and has greatly shortened experimental period, has improved efficiency of teaching, have save time, efficiently, characteristics intuitively.
For achieving the above object, the technical solution of the utility model is following design:
Described a kind of catalytic action demonstration device is characterized in that: described its main body of catalytic action demonstration device be a fragmented bottom 40mm～60mm local crooked 25 ℃～35 ℃ of angles, a diameter is arranged from the place of mouth of pipe 90mm～110mm is that the specification of 10mm～15mm projection is the hard processing Boiling tube (1) of 200mm * 30mm.
Described a kind of catalytic action demonstration device is characterized in that: the mouth of pipe of described catalytic action demonstration device is plugged with rubber stopper with double hole (4).
Described a kind of catalytic action demonstration device is characterized in that: be inserted with mercury thermometer (5) on the rubber stopper with double hole of described catalytic action demonstration device; Other is inserted with the verifier (6) that a check product is used.
Catalytic action demonstration device described in the utility model is used to drill the catalytic action in material.Place (3) to locate catalyzer during use, place (2) to locate other reactant, then (4), (5), (6) are assembled respectively, fix the catalytic action demonstration device, the material of earlier (3) being located the back to be located by (2) respectively under unmixed situation heats, can observation emit gas or emit required minimum temperature of gas or phenomenon, and write down.While hot (3) are located catalyzer impouring (2) and locate in the reactant, observing response is emitted the severe degree of gas again.Twice experiment compares, thus the catalytic action of understanding catalyzer.
The effect of catalytic action demonstration device described in the utility model depends primarily on following factor:
1, the one, whole device is air tight.Gas can only pass through verifier (6) and arrive in the air, could check gaseous product well like this, avoids experimental phenomena not obvious and error occurs.
2, the 2nd, thermometer inserts the degree of depth in the demonstration device can not be long and will be fixed up.Thermometer is inserted deeply excessively, may make measured temperature surpass the range of thermometer and damages thermometer; Be fixed up is to help doing the contrast experiment.
3, the 3rd, when experiment verifier (6) opening all the time and places the check thing up in advance.Because of verifier is uncovered,, puts the check thing earlier well and be convenient to the real-time test product so need opening up.
4, the 4th, install the reactant that (2) are located during experiment earlier, the catalyzer that back dress (3) is located.Can avoid catalyzer to mix at the very start like this with other reactant.

Describe the utility model in detail below in conjunction with the drawings and the specific embodiments:
A kind of catalytic action demonstration device that this embodiment is introduced, its structure is (1), (2), (3), (4), (5), (6) as shown in the figure.Described its main body of catalytic action demonstration device is local crooked 25 ℃～35 ℃ angles of a fragmented bottom 40mm～60mm, and it is that the specification of 10mm～15mm projection is the hard processing Boiling tube (1) of 200mm * 30mm that a diameter is arranged from the place of mouth of pipe 90mm～110mm.The mouth of pipe of described catalytic action demonstration device is plugged with rubber stopper with double hole (4).Plug mercury thermometer (5) and verifier (6) on the rubber stopper with double hole of described catalytic action demonstration device (4).This instrument user mode as shown in Figure 1.The catalytic action demonstration device is fixed on the iron stand (7) in heating process, lights spirit lamp (8) heatable catalyst earlier, from (6) observe phenomena; And then light alcohol and order (9) and heat other reactant, from (6) observe phenomena.Thereby some character of understanding catalyzer.Extinguish alcohol then and order (8) and (9), with in other reactant of catalyzer impouring,, further be familiar with the catalytic action of catalyzer while hot from (6) observe phenomena.
Claims (2)
1, a kind of catalytic action demonstration device is characterized in that: described its main body of catalytic action demonstration device be a fragmented bottom 40mm～60mm local crooked 25 °～35 ° of angles, a diameter is arranged from the place of mouth of pipe 90mm～110mm is that the specification of 10mm～15mm projection is the hard processing Boiling tube (1) of 200mm * 30mm.
2, a kind of catalytic action demonstration device according to claim 1, it is characterized in that: the mouth of pipe of described catalytic action demonstration device is plugged with rubber stopper with double hole (4), and a hole is inserted with mercury thermometer (5), and another hole is inserted with verifier (6).
