Summary of the invention: at the deficiency of using copper sulphate as feed addictive, technical problem to be solved by this invention is; Provide a little less than a kind of water-soluble low, redox power; Do not destroy nutritional labeling in the feed, can improve the crystal type basic copper chloride feed addictive that feed conversion is worth, and provide that a kind of technology is simple, cost is low, the preparation method of free of contamination crystal type basic copper chloride feed addictive.
Feed addictive of the present invention is the crystal type basic copper chloride, and its molecular formula is Cu
2(OH)
3Cl, chemical name are chlorination three hydroxyls two bronze medals.This compound is a kind of blackish green crystallization or crystalline powder, and is water insoluble, is dissolved in acid and ammoniacal liquor.
Its preparation method is as follows: (1) changes quantitative copper sulphate (or sulfate copper mine) in the reactor over to and adds the hydrochloric acid that salt that 0.5-2.5 doubly measures and 0.3-1.5 doubly measure, and temperature is controlled at 65-85 ℃, and the reaction time was at 4-8 hour;
(2) in the reactor slowly bubbling air make its oxidation, 5-10 hour, when concentration of hydrochloric acid reaches minimum, can stop blowing air during PH=5-6;
(3) leave standstill reactant liquor, treat its thorough post precipitation, emit reactant liquor and filter;
(4) thing that leaches that draws after will filtering places reactor, feeds the ammoniacal liquor of 2 times of amounts (or 1 times of amount) then, stirring reaction;
(5) react completely after, leave standstill reactant liquor, filter behind the crystalline deposit fully, and water (or alcohol) washing precipitate;
(6) sediment that draws after will filtering carries out drying, promptly gets the crystal type basic copper chloride;
(7) ammoniacal liquor that filters out (or alcohol) can carry out recycling by retracting device.
Because nutrient tool unstability, particularly vitamin and antibiotic are extremely sensitive to oxidation in the forage mixture.In fact, the destruction of vitamin etc. is that redox reaction by trace mineral causes in the forage mixture.Copper sulphate is the sky-blue crystalline powder, soluble in water, be insoluble to absolute ethyl alcohol, because it is water-soluble high especially, and there is moisture in the feed inevitably, so copper sulphate has higher redox ability in feed, and discharge copper ion, the oxidation of catalysis vitamin, antibiotic or other nutrient.The crystal type basic copper chloride is blackish green crystallization or crystalline powder, and is water insoluble, is dissolved in acid and ammoniacal liquor; Because of it is water-soluble low, a little less than the redox power, nutrition in the feed is produced destruction hardly, so just can improve the value of feed, extend the expiration date.
Production method of the present invention obtains the preferred process route through test of many times, screening, has advantages such as technology is simple, cost is low, pollution-free.Particularly be the method for raw material with copper sulphate, the time is short, the yield height, and purity is good, and finishing operation need not wash by alcohol, has reduced cost and the minimizing pollution to environment.
The specific embodiment:
One: 100 kilogram of copper sulphate of embodiment (content 〉=98%) adds in 500 kg of water, fully stirring back 200 kilograms of salt of adding stirs, add 100 kilograms of hydrochloric acid (content 〉=98%) again, temperature is controlled at about 65 ℃ fully reacted 4 hours, bubbling air makes its oxidation about 5 hours in reactor again, when reaching minimum, concentration of hydrochloric acid can stop blowing air during PH=5-6, leave standstill reactant liquor, treat its thorough post precipitation, emitting reactant liquor filters, leach thing and insert stirring reaction 2 hours (about 65 ℃) in 200 kilograms of ammoniacal liquor again, leave standstill reactant liquor, filter behind the crystalline deposit fully, and wash sediment with water, the sediment that draws after filtering is carried out drying, promptly get about 50 kilograms of crystal type basic copper chloride.
Two: 100 kilograms of sulfate copper mines of embodiment (copper content 〉=5%) add in 500 kg of water after being ground into 100 orders, fully stirring back 80 kilograms of salt of adding stirs, add 50 kilograms of hydrochloric acid (content 〉=98%) again, temperature is controlled at about 85 ℃ fully reacted 8 hours, bubbling air makes its oxidation about 10 hours in reactor again, when reaching minimum, concentration of hydrochloric acid can stop blowing air during PH=5-6, leave standstill reactant liquor, treat its thorough post precipitation, emitting reactant liquor filters, leach thing and insert stirring reaction 4 hours (about 65 ℃) in 100 kilograms of ammoniacal liquor again, leave standstill reactant liquor, filter behind the crystalline deposit fully, and use the alcohol washing precipitate, the sediment that draws after filtering is carried out drying, promptly get about 10 kilograms of crystal type basic copper chloride.

Table 3 pair daily ration thick protein digestibility, the influence of copper apparent digestibility and serum copper content
Project test group control group
The thick protein digestibility, % 79.56 ± 1.69 77.38 ± 0.86
The copper apparent digestibility, % 6.31 ± 0.76 4.47 ± 0.69
Serum copper, mg/L 1.65 ± 0.13 1.33 ± 0.19
Biological value 141 100
Concerning the thick protein digestibility, both do not see appreciable impact (P＞0.05, table 3) to it.The apparent digestibility of test group copper is significantly higher than control group, and difference is (P＜0.01) extremely significantly.This may be because the copper that exists with the basic copper chloride form changes or improved the absorption approach of copper, thereby has improved the apparent digestibility of copper.The serum copper content of test group is significantly higher than the serum copper content of control group (p＜0.01).The above results shows, the apparent digestibility of basic copper chloride and serum copper content add in feed and can improve biological value 41% all than copper sulphate height.

The excrement soluble copper, % 12.41 ± 0.10 14.60 ± 0.82
Can find out that from last table 4 under copper content condition with higher, test group reduces by 15% than control group excrement soluble copper content, moisture is also low in the excrement; Excrement copper content control group is significantly higher than test group.This is the result under high copper level still, if the low difference of copper level will be more obvious.This result shows that basic copper chloride can significantly reduce the discharging of copper, if copper ring environment pollution problem is mentioned a new height, then promoting the use of of basic copper chloride has very great significance.

From economic analysis (table 5) as can be seen, the basic copper chloride group also has superiority in economic benefit than copper sulphate group, but difference is little, in feed the copper sulphate change can't be increased cost for basic copper chloride.
Basic copper chloride is a kind of new copper source that makes an addition in the feed, compare the concentration of the copper of basic copper chloride higher (58.5%), the solubility in the water low (less than 1%) with copper sulphate, more be difficult for the moisture absorption (under 90% humidity, placing 24 hours a moisture absorption 0.46%).And the chemism of basic copper chloride is very low, and therefore the antagonism of energy minimizing and Fe, Zn has reduced the destruction to vitamin and other organic nutrient substances.Basic copper chloride is to the influence of growth performance, and comparing with copper sulphate does not have evident difference.And the digestibility of copper is higher, and excrement copper reduces, and particularly the content of excrement soluble copper is starkly lower than copper sulphate, and these characteristics all help reducing the pollution of copper to environment.In addition, basic copper chloride makes an addition to has the good homogeneous degree in the feed, lower than copper sulphate to the corrosivity of the feed-processing equipment and the apparatus of feeding.Integrating and see, substitute copper sulphate with basic copper chloride, all is feasible from still being economically on effect.Basic copper chloride has both environmental protection and relative inexpensive advantage as a kind of economical and practical product, adopts method of the present invention to make basic copper chloride and can further reduce its production cost.
