Embodiment
Consult shown in Figure 1, producing and bleaching property experimental provision of a kind of chlorine of the present utility model, comprise support 1, be provided with chlorine generating means 2 at support 1, in the present embodiment, described chlorine generating means 2 is made up of spirit lamp 2a, asbestos gauge 2b, flask 2c and separating funnel 2d, described spirit lamp 2a is placed on the support 1, described asbestos gauge 2b and flask 2c are fixed on the support 1 of spirit lamp 2a top from the bottom to top in regular turn, and described separating funnel 2d is arranged on the flask 2c by rubber stopper with double hole.The chlorine of described flask 2c exports in regular turn, and pipeline is connected with filtration unit 3, gas bottle 4, bleaching apparatus for demonstrating 5 and device for absorbing tail gas 6, the first demonstration bottle 5a and second that described bleaching apparatus for demonstrating 5 is connected by mutual pipeline demonstrates bottle 5b and is arranged on the dry coloured cloth 5c in the first demonstration bottle 5a and is arranged on the second moistening coloured cloth 5d that demonstrates in the bottle 5b and forms, the described first demonstration bottle 5a is connected with gas bottle 4 pipelines, draft tube on the described gas bottle extends to bottom in this bottle, because the density of chlorine is bigger than air.The described second demonstration bottle 5b is connected with device for absorbing tail gas 6 pipelines, and the draft tube on the described second demonstration bottle 5b extends to bottom in this bottle.
Further, filtration unit 3 is made up of the first narrow-mouthed bottle 3a of interior dress saturated aqueous common salt and the second narrow-mouthed bottle 3b of the interior dress concentrated sulphuric acid, and the effect of saturated aqueous common salt is to remove in the reaction unit with Cl
2The HCl gas that comes out together.Reason with saturated aqueous common salt is because of Cl in the saturated aqueous common salt
-The state that reached capacity can not absorb Cl
2The time can remove the HCl gas of blowing out; The effect of the concentrated sulphuric acid is to utilize its water absorptivity, to the Cl that generates
2Gas carries out drying; Be equipped with rubber stopper with double hole at the first narrow-mouthed bottle 3a, the second narrow-mouthed bottle 3b, the first demonstration bottle 5a and the second demonstration bottle 5b peristome; Described flask 2c, the first narrow-mouthed bottle 3a, the second narrow-mouthed bottle 3b, the first demonstration bottle 5a pass rubber stopper with double hole by conduit in regular turn with the second demonstration bottle 5b and are connected; The described draft tube that is positioned on the first narrow-mouthed bottle 3a and the second narrow-mouthed bottle 3b all extends to corresponding bottle bottom.Simultaneously, described device for absorbing tail gas 6 is made of the 3rd narrow-mouthed bottle of interior dress sodium hydroxide solution, and described the 3rd narrow-mouthed bottle peristome is provided with rubber stopper with double hole, and described the 3rd narrow-mouthed bottle passes rubber stopper with double hole with the second demonstration bottle 5b by conduit and is connected.Use sodium hydroxide solution, collect remaining Cl in the reaction
2This part sodium hydroxide solution concentration is big relatively.In order to prevent suck-back, the device of back also can be used the funnel of a back-off again with a large beaker.Reaction equation:
During work, at first in flask 2c, add MnO
2Solution adds dense HCl solution by separating funnel 2d then, and Cl is produced in reaction under the condition of heating
2Equation is as follows: MnO
2+ 4HCl (dense)===MnCl
2+ Cl
2↑+2H
2O, the chlorine of generation remove unnecessary HCl gas by saturated aqueous common salt in regular turn, by the concentrated sulphuric acid chlorine are carried out drying again, guarantee the carrying out of testing later; Chlorine enters in the first demonstration bottle 5a and the second demonstration bottle 5b in regular turn, and the dry coloured cloth 5c among the first demonstration bottle 5a is reactionless, and fading then appears in the moistening coloured cloth 5d among the second demonstration bottle 5b, and explanation is Cl
2With the reacted material of water cloth is faded.Absorb unnecessary chlorine by sodium hydroxide solution at last, guarantee that experiment is free from environmental pollution.
