Abstract
The present invention relates to an oxydol oxygen producing catalyst. Waterproof adhesive, such as hard polyvinyl chloride plastic (PVC-U), is uniformly stuck at the surfaces of clean dry sands or other insoluble solid granules with the diameter of 2 to 3mm; then powdery manganese dioxide is conglutinated on the waterproof adhesive to be made into three-in-one insoluble solid granular catalyst with catalyzing activity at the surface. The oxydol oxygen producing catalyst can ensure that the oxydol oxygen production in a lab can be controlled and achieved by a device similar as a kipp gas generator; the oxydol oxygen producing catalyst can be separated and recycled from oxydol reaction liquid and can be used in a respirator with the oxydol as oxygen supply catalyst.
Description
Affiliated technical field
The powder catalyst that the present invention relates to be used for producing oxygen from hydrogen peroxide is converted into the insoluble solid catalyst particle that the surface has catalytic activity, the laboratory can be controlled with the device of similar kipp gas generator with producing oxygen from hydrogen peroxide finish.
Background technology
The existing junior middle school chemistry teaching material of China is produced oxygen to hydrogen peroxide and has been listed the content of courses under the catalytic action of manganese dioxide, and draws the rudimental knowledge of catalyst with this.Because what use is Powdered manganese dioxide, it is not easily separated that manganese dioxide and hydrogen peroxide fully contact, and its catalytic action is out of control, and the speed that produces oxygen is too fast, can not control with the device of similar kipp gas generator; Powdered manganese dioxide inconvenience is reclaimed, and causes waste; Also the manganese dioxide that therefore inconvenience taking-up had then and there been used in classroom instruction carries out the reusable visual experiment demonstration of catalyst, thereby " one become two constant " characteristics of explaining illustration catalyst " can change the chemical reaction rate of other materials; and this is before and after the chemical reaction, its quality and chemical property do not change " well.
Summary of the invention
The present invention provides a kind of insoluble solid catalyst particle for producing oxygen from hydrogen peroxide.The laboratory can be finished with the device of similar kipp gas generator with producing oxygen from hydrogen peroxide; And be convenient in time reclaim carry out the reusable experimental demonstration of catalyst, be convenient to notion and characteristics that the student understands and masters catalyst.
The technical solution adopted for the present invention to solve the technical problems is: at the gluing marine glue of the grains of sand or other insoluble solid granules surface of dried and clean; adhering powder shape manganese dioxide on marine glue is made " three-in-one " insoluble solid catalyst particle that the surface has catalytic activity again.When being used for producing oxygen from hydrogen peroxide and making catalyst, easily separate with the hydrogen peroxide reactant liquor; Manganese dioxide is not come off by marine glue is firmly gluing; Can use the device of similar kipp gas generator to control finishes.
The invention has the beneficial effects as follows: when 1. being used for the laboratory producing oxygen from hydrogen peroxide and making catalyst, easily separate with the hydrogen peroxide reactant liquor, reaction rate is gentle, thus the device of available similar kipp gas generator finish, reach the system oxygen effect of ready access upon use.2. can reclaim the repeated use of demonstration catalyst then and there, both favourable teaching also cuts the waste.3. also can be used for the oxygen supply of used for respirators hydrogen peroxide and make catalyst.
The specific embodiment
Cut-off directly is the grains of sand (or other insoluble solid granules) of 2～3mm, with drying after the clear water flushing, pours marine glue (as the quick adhesive of rigid PVC (PVC-U)) then into and stirs, and makes the even gluing marine glue of solid particles surface; The limit is poured Powdered manganese dioxide limit into and is constantly stirred then, with form between particle, the particle non-caked mutually till; Dry the back and immerse the clear water stirring, remove the unnecessary Powdered manganese dioxide of particle surface, dry standby once more after the flushing.
Claims (3)
1, a kind of catalyst for producing oxygen from hydrogen peroxide; it is characterized in that: at the even gluing hard marine glue of the grains of sand of dried and clean or other insoluble solid granules surface [as rigid PVC (PVC-U) adhesive etc. fast], adhering powder shape manganese dioxide on its marine glue then.
2, according to the described catalyst for producing oxygen from hydrogen peroxide of claim 1, it is characterized in that: the innermost layer is the insoluble solid granule, can be that river sand also can be other insoluble solid granules.
3, according to the described catalyst for producing oxygen from hydrogen peroxide of claim 1, it is characterized in that: marine glue is hard marine glue [as the quick adhesive etc. of rigid PVC (PVC-U)].
