Description
Technical field
The present invention relates to a kind of halid preparation method of zinc, relate in particular to a kind of preparation method of basic zinc chloride that can be used as fodder additives.
Background technology
Basic zinc chloride is as a kind of new zinc source feed additive; with respect to conventional zinc sources such as zinc oxide and zinc sulfate; have that the interpolation level is low, consumption is few, advantage such as good palatability, biological value height and feeding effect are good; and more help protecting environment, be a kind of safe, efficient, environmental protection and comprehensive effects novel fodder additive.In the process for producing of present existing basic zinc chloride, useful useless zinc is produced, and useful zinc chloride and zinc oxide reaction are produced, also useful hydrochloric acid and zinc oxide react to be produced, these preparation methods are faced with a common shortcoming, and promptly raw material is relatively costly, and production cost is too high.
Summary of the invention
The technical problem to be solved in the present invention is to overcome the deficiencies in the prior art, the method for preparing microelement additive basic zinc chloride that provide a kind of safety simple to operate, waste discharge is few, production cost is low and the product quality is better.
For solving the problems of the technologies described above, the technical scheme that the present invention proposes is a kind of method for preparing microelement additive basic zinc chloride, it is characterized in that: zinc subcarbonate is rendered in the hydrochloric acid soln, the mol ratio of hydrogen chloride content is 2: 4 in the consumption of zinc subcarbonate and the hydrochloric acid soln, in temperature is that 60～95 ℃, pH value are under 5～8 the condition, reacts to obtain reaction product after 0.5～2 hour; The chemical equation of this reaction is as follows:
2[ZnCO
3Zn
2(OH)
4H
2O]+4HCl+H
2O=Zn
5(OH)
8Cl
2H
2O+ZnCl
2+ 2CO
2↑+4H
2O with the reaction product washing that obtains, centrifugation, drying after, make basic zinc chloride.The basic zinc chloride that makes is pulverized, and after packing, can be obtained the basic zinc chloride finished product as fodder additives, zinc content can reach 57.5～61.5% in the finished product.
As a further improvement on the present invention, remaining reaction solution and zinc oxide after the above-mentioned centrifugation can be carried out subsequent reactions, with after the further centrifugation of subsequent reactions product, the oven dry, prepare basic zinc chloride again, the chemical equation of this subsequent reactions is as follows:
ZnCl
2+4ZnO+5H
2O＝Zn
5(OH)
8Cl
2·H
2O
By this subsequent reactions, realized recycling simultaneously to reaction solution in the technique scheme.
The mass concentration of employed hydrochloric acid soln is 6～18% in the technique scheme.
Compared with prior art, the invention has the advantages that: the acidity by utilizing hydrochloric acid and the weakly alkaline of zinc subcarbonate are directly carried out neutralization reaction under the situation of water that responds, and need not to add other promotion reagent, reacted product carries out can obtaining the basic zinc chloride finished product after centrifugation, the drying.Basic zinc chloride by method preparation of the present invention, not only can improve the purity of basic zinc chloride, and the raw materials for production that the by product liquor zinci chloridi can be used as another basic zinc chloride preparation technology reuse, the carbon dioxide that reaction generates also can be recycled separately, almost non-pollutant discharge.Operational path of the present invention is simple, operation easily, and the price of raw materials for production is lower, and production cost is little, and constant product quality and detrimental impurity content are low, and can satisfy the requirement of environment protection and cleaner production.
In addition, with the basic zinc chloride feeding animals that the present invention makes, animal not only absorbs soon, and the absorption rate height.For example:
The additive that makes with the present invention feeds pigs by the standard consumption in zinc source, can promote growth, improves feedstuff-meat ratio, improves yellowish pinkly, improves its resistance against diseases, and makes the pigskin skin ruddy, the hair color light; Feed piglet and can improve anti-stress ability and the immunizing power of piglet, promote its growth, prevention suckling piglet diarrhea; Feed boar and can prolong the breeding work-ing life of boar;
Feed poultry with the additive that the present invention makes by the standard consumption in zinc source, its speed of growth is improved, feedstuff-meat ratio descends, and strengthens the feather glossiness, improves its stress ability, reduces mortality ratio;
Feed aquatic animal with the additive that the present invention makes by the standard consumption in zinc source, can strengthen its immunizing power, reduce incidence and mortality, promote to produce, reduce disease and take place, improve efficiency of feed utilization thereby reduce water-soluble loss.
Embodiment
Embodiment 1:
Prepare basic zinc chloride by following reactions steps: get the 39.5g mass concentration earlier and be 37% concentrated hydrochloric acid, with 80ml water concentrated hydrochloric acid is diluted, again the zinc subcarbonate of 68.4g is slowly put in the hydrochloric acid after the dilution, regulating the pH value under 75 ℃ temperature of reaction is 6.5, reaction is 1 hour under the condition of normal pressure, through washing, centrifugation, oven dry, pulverizing, prepare the basic zinc chloride finished product at last again.Zinc content is 58.5% in this finished product.With the reaction solution after the above-mentioned centrifugation is reaction 1 hour under 95 ℃ the condition of normal pressure in temperature of reaction with 32.56g zinc oxide again, again through washing, centrifugation, oven dry, pulverizing, also prepares the basic zinc chloride finished product, and zinc content is 59.6% in this finished product.
Embodiment 2:
Prepare basic zinc chloride by following reactions steps: earlier be that 36.5% concentrated hydrochloric acid is put in the reactor that adds the 1000Kg reaction water and fully stirred with the 400Kg mass concentration, again the zinc subcarbonate of 685Kg is slowly put in the reactor with dilution after hydrochloric acid react, regulating the pH value under 80 ℃ temperature of reaction is 7, reaction is 1.5 hours under the condition of normal pressure, through washing, centrifugation, oven dry, pulverizing, prepare basic zinc chloride finished product 551Kg at last again.Zinc content is 59% in this finished product.Reaction solution after the centrifugation is reaction 50 minutes under 95 ℃ the condition of normal pressure in temperature of reaction with 325Kg zinc oxide again, again through washing, centrifugation, oven dry, pulverizing, prepares basic zinc chloride finished product 550Kg, and zinc content is 59.3% in this finished product.
Because the price of zinc subcarbonate (in zinc) is than zinc oxide (in zinc) low about 30% on the market, and the consumption that use zinc subcarbonate or zinc oxide prepare the required hydrochloric acid of basic zinc chloride is the same, therefore in the various embodiments described above, by adopting zinc subcarbonate to replace raw materials such as zinc oxide, useless zinc to prepare basic zinc chloride, make the production cost of enterprise reduce greatly.
