The copper glycine chelating technology comprises the following steps of blending glycine and copper sulfate according to a ratio of 2.1-2.5: 1, adding 20-30wt% of water into the mixture, carrying out stirring, carrying out appropriate drying until copper glycine chelate water content is in a range of 10-20%, carrying out full grinding, and carrying out a chelating reaction process at a reaction temperature of 20-40 DEG C for 80min.
Description
Technical field
The present invention relates to a kind of glycocoll-copper chelating technology, belong to novel fodder additive technical field.
Background technology
Copper has very high nutritive value, organism metabolism many in all play a significant role, one of trace element of animal life activity, improving food conversion ratio, improve reproductive performance, strengthen animal disease resistant ability, improve livestock product quality etc. in play an important role.Glycocoll-copper is a kind of organic copper sources of high-quality, its steady chemical structure, palatability are good, bioavailability is high, environmental pollution is also low than Inorganic Copper simultaneously, and therefore, glycocoll-copper relies on its superiority progressively will to play the effect larger than Inorganic Copper in feedstuff industry.
The chelating technique of current glycocoll-copper mainly contains aqueous systems synthesis method, enzymolysis process, acid hydrolyzation, acid-base method and acid-enzyme hydrolysis method, exist long reaction time, cost high, use that a large amount of acid solution or alkali lye, by product are many, the shortcoming such as waste liquor contamination, complex process; Microwave solid source synthesis inner complex, has that speed of response is fast, less energy consumption, technique simple, waste liquid and an advantage such as environmental pollution is little.But there is easy coking by-products and not easily realize the problem of heavy industrialization in microwave radiation; Indoor temperature solid phase method is emerging synthetic method, have that reaction preference is high, side reaction is few, do not use solvent, advantage that environmental pollution is little, but there is the problems such as chelating is not thorough, unstable, at present, the glycocoll-copper chelation percent more than 90% of organic solvent precipitation method.
Summary of the invention
The present invention overcomes the deficiencies in the prior art, technical problem to be solved be to provide a kind of reaction preference high, without side reaction, do not use soda acid and organic solvent, free from environmental pollution, the glycocoll-copper chelating technology that chelate stability is good, solvability is good.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of glycocoll-copper chelating technology, comprises the steps, is mixed by glycine with the coordination ratio of copper sulfate by 2.1-2.5:1, the water adding mixture total mass 20%-30% stirs, abundant grinding, carries out chelatropic reaction, suitably dry, the moisture content being dried to glycocoll-copper inner complex is 10%-20%, the temperature of reaction of chelatropic reaction is 20 DEG C-40 DEG C, and reaction times 80min, obtains finished product.
As preferred a kind of glycocoll-copper chelating technology, comprise the steps, mixed with the coordination ratio of copper sulfate by 2.3:1 by glycine, the water adding mixture total mass 25% stirs, suitably dry, the moisture content being dried to glycocoll-copper inner complex is 15%, abundant grinding, carries out chelatropic reaction, and the temperature of reaction of chelatropic reaction is 30 DEG C, reaction times 80min, obtains finished product.
Compared with prior art the invention has the beneficial effects as follows: in the present invention, glycine and copper sulfate coordination ratio are a little more than the 2:1 in traditional technology, suitably excessive glycine, contribute to generating glycocoll-copper direction at molecular balance to chelating to move, increase the utilization ratio of copper sulfate, and keeping glycocoll-copper stability, chelation percent of the present invention can reach more than 95%; Add appropriate moisture content to stir, solve traditional indoor temperature solid phase method Raw mixing problem of non-uniform; Without the interpolation of anacidity, alkali and organic reagent in process engineering, adding without poisonous and harmful substances, whole technological process achieves cleaner production, the glycocoll-copper chelating technology that chelate stability is good, solvability is good.
