Embodiment 1

[0033] Example 1 (prior to reaction, 85 ° C, 4H, 2%, Gly-Cu; 2: 3)

[0034] 34.4GCUCL 2 · 2h 2 O Soluble in 150 ml of pure water, add 0.9 g of glycine copper chelate to the above-mentioned copper chloride solution to transfer 500 ml of four flasks 50 ° C to heat insulation; weigh 24.1 GCUO and 150 ml of pure water to be configured into suspension, one and In the 500 ml of the four-mouth flask, stirring to obtain a black suspension mixing system, heating to 85 ° C insulation reaction for 4 h, the reaction ends naturally cooling to the system 30 ~ 40 ° C, filtration washing, washed with light green microstructure, 105 ° C dry to constant weight, Light green micro-blue powder solid M1: Net weight 41.25g, good fluidity, slightly gloss, analyzed the solid copper content: 58.44%. The mother liquor is about 250 ml of microfluorescent stated: remembered MY-01, its pH is 3.11.

Embodiment 2

[0035] Example 2 (Circulation 1)

[0036] Take the first mother liquor MY-01, adjust its pH = 2.5 to 2.7 with a 10% hydrochloric acid solution, resulting in the regeneration mother liquor 1, take 150 ml of regenerated mother liquor 1 to dissolve 17.2GCUCL 2 · 2h 2 O, the blue-green solution is transferred to 500 ml of four flasks and then add 0.9 g of glycine chelating copper 50 ° C to be used; the remaining regenerative mother liquor is supplied into a small amount of pure water to 150 mL and 24.1 GCUO is configured into a suspension, add the aforementioned 500 ml of flask , Stirring to obtain a black suspension mixing system, warming to 85 ° C stirring insulation reaction for 4 h, the reaction ends naturally cooling to the system 30 to 40 ° C, the filtration is washed with light green micro-blue solid, 105 ° C dry to constant weight, light green microstru Powder solid M1: net weight 40.78g, good fluidity, slightly gloss, analyzed the solid copper content: 58.26%. The mother liqu...

Embodiment 3

[0037] Example 3 (before, 70 ° C, 2H, 5%, GLYCU)

[0038] Operation with Example 1, only the reaction temperature was reduced to 70 ° C, and the amount of glycine chelating copper was increased to 2.1 g (5 wt%), and the reaction time was shortened to 2 h. Finally, the delaid powder solid M3: net weight is 43.44 g, the fluidity is good, slightly gloss, analyzed the solid copper content: 57.85%. The mother liquor is about 280 ml of microfluorescent stickers: remembered MY-03, its pH of 2.97.

Abstract

The invention relates to the technical field of feed additives, in particular to dispersing type copper chloride hydroxide and a preparation method thereof, the dispersing type copper chloride hydroxide and an amino acid copper chelate are prepared, the percentage content of the amino acid chelate is 1-10w%, the amino acid chelate is glycine chelated copper and / or methionine chelated copper, and the content of the amino acid chelate is 1-10w%. The preparation method comprises the following steps: preparing a mixed system containing the dispersing aid, copper chloride and copper oxide, reacting the mixed system at 45-105 DEG C for 2-5 hours to obtain a product system, and carrying out solid-liquid separation on the product system to obtain the product dispersing type basic copper chloride and mother liquor. The method overcomes the defects that in the prior art, a crystallization scheme is complex, copper-containing ammonium chloride wastewater needs to be treated, non-nutritional auxiliary dispersion or crystallization auxiliary materials need to be added and the like, so that the technological process is increased, and the effective content of the product basic copper chloride is reduced.

Description

Technical field [0001] The present invention relates to the field of feed additives, and more particularly to a dispersed alkali-type chloride and a preparation method thereof. Background technique [0002] Copper has an important role in maintaining normal metabolism and immunity in the body. Feeding tests show that the addition of high copper can increase the daily weight, feed and feed efficiency of animals in feed, and has the effect of promoting growth. Alkali-type copper, molecular formula Cu 2 (OH) 3 CL is an excellent animal trace element nutrition additive for supplementing the trace element copper required for animal growth health, which has the advantages of high bioavailability, good stability and high copper content relative to traditional sulfate additives. [0003] Base-based chloride is difficult to solute in water, the obtained product prepared by the product is a very fine base-type chloride powder, and the powder-shaped alkali chloride wet material has a certai...
