Problems solved by technology

The existing nickel source feed additives are mainly inorganic nickel salts, which have a large amount of addition and low absorption and utilization rate, which cannot be effectively absorbed and utilized by animals, and the emission is large during the production process, which is likely to cause serious pollution to the environment
[0004] In the existing literature, there is no report on the combination of glycine and nickel as an animal feed additive

Embodiment 1

[0022] In this example, nickel sulfate or nickel sulfate crystal hydrate and glycine aqueous solution are mixed and reacted at a reaction temperature of 40°C to 100°C and a reaction pH value of 5 to 7, and the reaction is obtained for 1.5h to 4.5h. product.

[0023] Through the basic principles and laws of chemical reactions, we can preliminarily determine that the reaction product may be a new glycine chelate—nickel glycine; The structural analysis of infrared analysis and X-ray diffraction further confirms that reaction product is nickel glycinate of the present invention.

[0024] Wherein, the mol ratio of the crystalline hydrate of nickel sulfate or nickel sulfate and glycine is (0.8~1.1): 1, when the mass concentration of glycine aqueous solution is 6.5%~15%, reaction is complete, raw material utilization is sufficient, the nickel glycine purity of preparation High, less impurities, better effect.

[0025] The reaction product nickel glycinate obtained above was evapora...

Embodiment 2

[0030] This Example 2 prepares the nickel glycine of the present invention through the following reaction steps: Measure 100mL of water and pour it into a 250mL reaction cup, turn on the stirring device, put 7.5g of glycine into the reaction cup at room temperature, heat to 50°C to dissolve the glycine, Add 26.3g of nickel sulfate hexahydrate into it, react at a constant temperature of 90°C for 3 hours, evaporate the reaction product to dryness at 95°C, put it into a tray to crystallize, send it to a drying room for drying, the drying temperature is controlled at 105°C, and finally crushed to obtain finished product. By carrying out the analysis of nickel, glycine content to the finished product after above-mentioned reaction, and the structural analysis of conventional infrared analysis and X-ray diffraction, confirm that reaction product is nickel glycine of the present invention, and the molecular formula of this finished product is:

[0031] [CH 2 (NH 3 )COONiOOCCH 2 (N...

Embodiment 3

[0033] The present embodiment 3 prepares the nickel glycine of the present invention through the following reaction steps: take 1750kg of water and pour it into the reactor, turn on the stirring device, put 262.5kg of glycine into the reactor at normal temperature, and then add 918kg into it after heating to 53°C Nickel sulfate hexahydrate was reacted at a constant temperature of 75°C for 2.5 hours, and the reaction product was evaporated to dryness at 93°C, crystallized in a tray, sent to a drying room for drying, and the drying temperature was controlled at 108°C, and finally crushed to obtain a finished product. By carrying out the analysis of nickel, glycine content to the finished product after above-mentioned reaction, and the structural analysis of conventional infrared analysis and X-ray diffraction, confirm that reaction product is nickel glycine of the present invention, and the molecular formula of this finished product is:

[0034] [CH 2 (NH 3 )COONiOOCCH 2 (NH ...

Abstract

The invention discloses a glycinate chelate of nickel glycinate. The molecule structural formula of the nickel glycinate is shown as [CH2(NH3)COONiOOCCH2(NH3)]SO4.XH2O, and a value of X is between 0 and 10. The nickel glycinate is obtained after nickel sulfate or a crystalline hydrate of the nickel sulfate is mixed with a glycine aqueous solution to react. The nickel glycinate can be used as an animal feed additive. The application method is simple, is convenient for operation and obtains quite obvious feeding effect after breeding pigs, poultry and ruminants.

Description

technical field [0001] The invention belongs to the field of feed additives, in particular to a glycine chelate and its preparation method and application. Background technique [0002] Glycine, also known as aminoacetic acid and aminoacetic acid, is the amino acid with the simplest chemical structure, and it is also a non-essential amino acid in animals. It is an inhibitory neurotransmitter in the central nervous system, and is often considered to have no obvious function in other tissues. , Only provide nitrogen source for the synthesis of other amino acids. However, recent studies have found that it also has anti-inflammatory, immune regulation and cell protection effects. Animal experiments show that it plays an effective therapeutic role in various diseases such as ischemia-reperfusion injury, shock, alcoholic hepatitis, liver cirrhosis, arthritis, acute necrotizing pancreatitis, tumor and drug poisoning. [0003] The trace element nickel is involved in the metabolism...
