Abstract
The invention relates to a high-purity cuprous oxide preparation method. According to the method, used raw materials is copper powder; the copper powder is soaked by a hydrochloric acid solution, and is then washed by distilled water; the washed copper powder is conveyed into a rotary oxidation kiln; oxidation is performed at a low temperature until all copper powder becomes black; the temperature of the oxidation kiln is fast raised to 950 DEG C; under the continuous rotation of the oxidation kiln, high-temperature oxidation is maintained for 90 minutes; all black powder becomes bright red; cuprous oxide powder is taken out; the temperature is lowered to normal temperature under the nitrogen gas protection. The cuprous oxide is soaked by a saturated sodium chloride solution at normal temperature, and is then washed by 90 percent ethyl alcohol. The washed cuprous oxide is subjected to suction filtration under the nitrogen gas protection.
Description
Technical field
The present invention relates to fine chemical material production technical field is and in particular to a kind of cuprous preparation side of high-purity mangesium oxide
Method.
Background technology
Cuprous oxide is a kind of important Inorganic Chemicals, urges in coating, glass, pottery, plastics, agricultural and industry
There is extensive purposes in the fields such as agent.At present, the preparation method of cuprous oxide mainly has dry method, wet method and electrolysis.Electrolysis
Method power consumption is high, yields poorly, the product quality of cuprous oxide is also than relatively low.
Content of the invention
The technical problem to be solved is for the deficiencies in the prior art, provides a kind of new cuprous oxide to prepare
Technology.
The technical problem to be solved is to be realized by following technical scheme.By copper powder hydrochloric acid solution
Soak, with distilling water washing, send in rotation oxidation kiln, be oxidizing at low temperature when all becoming black, kiln will be aoxidized rapidly
Temperature brings up to 950 DEG C, and oxidation kiln maintains high-temperature oxydation 90 minutes under continuous rotation, and black powder is all changed into cerise,
Take out cuprous oxide powder, be down to normal temperature under nitrogen protection.The sodium chloride solution of cuprous oxide saturation is soaked at normal temperatures
Bubble, is washed with 90% ethanol.Will washing after cuprous oxide suction filtration under nitrogen protection.
Compared with prior art, the cuprous oxide purity of present invention preparation is high, and size is little, can apply to solar energy and turns
Change, the aspect such as electronics, magnetic storage device, bio-sensing and catalysis.
Specific embodiment
Pickling.Copper powder is soaked 30 minutes with 20% hydrochloric acid solution, and is stirred continuously, filter.Filter residue copper powder is distilled
Water washing 4 times.
Low-temperature oxidation.Copper powder is sent in rotation oxidation kiln, fully oxidized 60 minutes at 700 DEG C.
High-temperature oxydation.When copper powder all becomes black powder, rapidly oxidation kiln temperature degree is brought up to 950 DEG C, aoxidize kiln
Maintain high-temperature oxydation 90 minutes under continuous rotation, black powder is all changed into cerise, take out cuprous oxide powder, in nitrogen
Protection drops to normal temperature.
Salt soaks.The sodium chloride solution of cuprous oxide saturation is soaked 12 hours at normal temperatures, filters, with 90% ethanol
Washing 4 times.
Be dried, will after washing cuprous oxide suction filtration, to 0.03 MPa, takes out, airtight preservation is under nitrogen protection
Can.
