Abstract
The invention discloses a preparation method of basic cupric carbonate, which comprises the following steps: step 1, stirring the solid basic cupric carbonate or cupric hydroxide and water into a paste shape in a reactor; step 2, adding solid sodium bicarbonate in the reactor to carry out solid state reaction and controlling the temperature to be between 20 DEG C and 140 DEG C; and step 3, after the completion of measurement and conversion, firstly preparing the wet basic cupric carbonate and then preparing the finished wet basic cupric carbonate after the wet basic cupric carbonate are subjected to solid-liquid separation, and washed and dried. The invention has the advantages of high purity, low cost and less amount of waste water produced.
Description
Technical field
The present invention relates to the Chemical Manufacture career field, relate in particular to a kind of preparation method of basic cupric carbonate.
Background technology
Ventilation breather is a kind of important catalyst, industrial chemicals and wood preservation raw material, and the synthetic method of ventilation breather mainly is to synthesize generation ventilation breather with yellow soda ash or sodium hydrogen carbonate solution with copper sulfate, cupric chloride or cupric nitrate under dissolved state at present.This technology is because be synthetic under solution state, so the liquor capacity amount is big, because synthesize and to be heated to comparatively high temps, so energy expenditure is big, the wastewater flow rate that produces is big, it is higher to produce the concentration of byproduct sodium chloride in the aqueous solution in synthetic, so be difficult for the sodium-chlor in the product is cleaned separation, and the usage quantity of rinse water is also very big, and the fineness of product is uncontrollable, and the purity of product can't reach market demand, so this technology cost height, the big pollution of wastewater flow rate is heavy, yields poorly, and energy consumption is big, quality product is wayward.
At present, the main application of basic carbonate copper products is chemical reagent, plating and mantoquita Chemical market, the ventilation breather of most of market demand, metal ion is low just can, but wood preservation is world today's new industry, it not only requires the purity height, also requires fineness regulating YIN and YANG ionic purity.In the past because production technology does not reach the purity of market demand, so can't satisfy market demand.
Summary of the invention
Technical problem to be solved by this invention is the defective that overcomes prior art, and a kind of purity height, low, the few preparation method of basic cupric carbonate of generation wastewater flow rate of cost are provided.
For solving the problems of the technologies described above, the invention provides a kind of preparation method of basic cupric carbonate, comprise following process steps:
Step 1: the solid-state and water of alkali type nantokite or copper hydroxide is stirred into pulpous state in reactor;
Step 2: add solid sodium bicarbonate and carry out solid state reaction in reactor, temperature is controlled between 20 ℃-140 ℃;
Step 3: make wet product ventilation breather, after solid-liquid separation, washing and drying, make the ventilation breather finished product.
Wherein, described alkali type nantokite comprises basic copper nitrate or Basic Chrome Sulphate or basic copper chloride.
Because adopt technique scheme, the present invention has following beneficial effect:
Adopting the synthetic ventilation breather of single stage method mainly is that basic copper nitrate or Basic Chrome Sulphate or basic copper chloride or copper hydroxide are generated ventilation breather with the direct solid reaction of sodium bicarbonate in water, through centrifugation, be finished product after washing back air stream drying or the drying room drying.Have purity height, low, the few advantage of generation wastewater flow rate of cost.
Description of drawings
Fig. 1 is a process flow sheet of the present invention.
Embodiment
As shown in Figure 1, preparation method of basic cupric carbonate of the present invention comprises following process steps:
Solid-state and the water of alkali type nantokite (comprising basic copper nitrate or Basic Chrome Sulphate or basic copper chloride or copper hydroxide) or copper hydroxide is stirred into pulpous state in reactor; Add solid sodium bicarbonate and carry out solid state reaction in reactor, temperature is controlled between 20 ℃-140 ℃;
Wherein, chemical equation is:
Measure to transform finish after, the basic carbonate copper slurry is put down, after press filtration or suction filtration Xian Di are up to standard, make the ventilation breather finished product more after drying.
Particularly the raw material basic copper chloride is very abundant in the above-mentioned reaction, because China is the big producing country of electronic circuit board in the world, the sector has generated a large amount of copper-containing wastewaters aborning, at present domestic mainly is with its synthetic basic copper chloride or hydroxide copper sludge, generate copper sulfate with sulfuric acid reaction again, basic copper chloride and hydroxide copper sludge are used for electrolytic copper, copper sulfate is used for agricultural chemicals, all belong to rudimentary raw product, and supply exceed demand, and the profuse basic copper chloride of raw material is produced ventilation breather, not only turn waste into wealth but also can satisfy external requirement of client.
It should be noted that at last: above embodiment only in order to the explanation the present invention and and unrestricted technical scheme described in the invention; Therefore, although this specification sheets has been described in detail the present invention with reference to each above-mentioned embodiment,, those of ordinary skill in the art should be appreciated that still and can make amendment or be equal to replacement the present invention; And all do not break away from the technical scheme and the improvement thereof of the spirit and scope of the present invention, and it all should be encompassed in the claim scope of the present invention.
Claims (2)
1, a kind of preparation method of basic cupric carbonate is characterized in that: comprise following process steps:
Step 1: the solid-state and water of alkali type nantokite or copper hydroxide is stirred into pulpous state in reactor;
