Abstract
The present invention relates to a kind of novel process of producing ventilation breather, it uses CuSO
45H
2O and sodium bicarbonate are raw material, adopt following operation: mixed dissolution → boiling water reaction → minute filter → crystallization → freeze-day with constant temperature → check and make high purity ventilation breather cheaply is suitable for all kinds of chemical enterprises and produces in batches.
Description
The present invention relates to a kind of novel process of producing ventilation breather.
Ventilation breather is made purposes widely at medicine, chemical industry, national defence and other numerous areas, and special industrial producer that produces ventilation breather of domestic and international now none family still, just in comprehensive chemical reagent factory, with copper sulfate and soda ash is that main raw material is produced on a small quantity, people do not specialize in its manufacture craft, thereby it is very little in batches, far can not satisfy market demand, and product trash content height, the cost height.
The present invention studies the manufacture craft of ventilation breather, sums up the easy production technique of a cover, thereby realizes the purpose of production in enormous quantities, and the product purity height, and cost is low.
As Fig. 1 is technological process of production figure of the present invention.Whole process flow is like this:
Mixed dissolution → boiling water reaction → minute filter → crystallization → freeze-day with constant temperature → check.
Mixed dissolution is to be 2.29 first grade CuSO with proportion
45H
2O and the sodium bicarbonate (NaHCO that meets " Pharmacopoea Chinensis " specification
3) in scale tank (1) in the i.e. (CuSO of 1: 2 ratio
45H
2O): (NaHCO
3After porphyrize is mixed in)=1: 2, send dissolving in the dissolving tank (2); The boiling water reaction is with the mixed solution after the abundant stirring and dissolving, sends into and carries out chemical reaction (main body reaction), CO in the boiling water still (3)
2Gas is discharged from still tower upper discharge hole, and reaction conditions is that 100 ℃～200 ℃ its chemical formulas of normal pressure constant temperature are:
Dividing filter is last operation hot solution and precipitation to be sent in the separating filter (4) separates, and liquid is evaporated moisture content from the discharge of separating filter bottom, crystallization and obtain sodium sulfate, Cu
2(OH)
2CO
3Then it is sent in the crystallization kettle (5) by vacuum fan; Crystallization is with the Cu after minute filter
2(OH)
2CO
3Coarse-grain, the roasting under 100 ℃～300 ℃ constant temperature of the stoving oven in freeze-day with constant temperature chamber (6) is purified then and is obtained Cu
2(OH)
2CO
3Crystal obtains finished product with carrying out the constant temperature recrystallization again after the pure water washing; Check is the Cu with the recrystallization after drying
2(OH)
2CO
3Crystal carries out stochastic sampling and detects, and obtain Cu if produce according to above-mentioned operation
2(OH)
2CO
2＞99.9%, undissolved residue＜0.01%, proportion are 4 the Powdered ventilation breather of sap green monocline.
Operation that the present invention's employing is very easy and equipment are suitable for all kinds of large, medium and small chemical enterprises and adopt for the industrialized mass of ventilation breather provides an approach.
Description of drawings: Fig. 1 is technological process of production figure of the present invention.
(1) is scale tank among the figure, and (2) are dissolving tank, and (3) are reactor, and (4) are separating filter, and (5) are crystallization kettle, and (6) are the freeze-day with constant temperature chamber.
Embodiment and matters needing attention:
Producing one ton of basic carbonate copper raw material consumption according to aforementioned operation is: CuSO
45H
2The O1.5 ton, NaHCO
31.5 ton, 1000 meters in water
31000 kilowatts/time of Electric, 1 ton in coal.In the boiling water still, carry out boiling water when reaction, 200 ℃ of of boiled water temperature should be controlled at below, otherwise as equation:
Represented, ventilation breather will be decomposed into cupric oxide, and carbonic acid gas and water are in addition because Cu
2(OH)
2CO
3d
20℃=4, can check the insoluble foreign matter content of the finished product whether to be less than 0.01% so pack with constant weight.
Claims (4)
1, a kind of Alikali cupric carbonate produced by boiling water [Cu
2(OH)
2CO
3] method, it is characterized in that ventilation breather that described method is produced is is 2.29 CuSO with proportion
45H
2O and the sodium bicarbonate (NaHCO that meets " Pharmacopoea Chinensis " specification
3) make through following operation by 1: 2 proportioning as raw material: mixed dissolution → boiling water reaction → minute filter → crystallization → freeze-day with constant temperature → check.
2, method according to claim 1 is characterized in that Crystallization Procedure is the Cu that obtains after minute filter operation
2(OH)
2CO
3Coarse-grain is finished under the condition of 100 ℃～300 ℃ of constant temperature calcinings.
As method as described in the claim 1,2, it is characterized in that after Crystallization Procedure that 3, its product is again with sending the freeze-day with constant temperature operation dry and obtain the finished product after the pure water washing.
4, method according to claim 1 is characterized in that in the boiling water reaction process boiled water temperature is below 200 ℃, is preferably 100 ℃ and be reflected under the normal pressure and carry out.
