Embodiment 1

[0022] In this embodiment, nickel sulfate or nickel sulfate crystal hydrate and threonine aqueous solution are mixed and reacted at a reaction temperature of 40° C. to 100° C. for 1.5 hours to 3.5 hours to obtain a reaction product.

[0023] By the basic principles and laws of chemical reactions, we can preliminarily determine that the reaction product may be a new threonine chelate—nickel threonine; The analysis of the content, as well as the structure analysis of conventional infrared analysis and X-ray diffraction, further confirm that the reaction product is the nickel threonine of the present invention.

[0024] Wherein, the molar ratio of nickel sulfate or the crystalline hydrate of nickel sulfate to threonine is (0.8~1.1): 1, and when the mass concentration of threonine aqueous solution is 15%~25%, the reaction is complete, the raw materials are fully utilized, and the preparation The threonine nickel has high purity, less impurities and better effect.

Embodiment 2

[0030]In Example 2, nickel threonine of the present invention was prepared through the following reaction steps: Measure 100mL of water and pour it into a 250mL reaction cup, turn on the stirring device, put 23.8g of threonine into the reaction cup at room temperature, and heat to 50°C Afterwards (all the materials are dissolved), 52.6g of nickel sulfate hexahydrate is added thereto, reacted at a constant temperature of 60°C for 2.5 hours, and the reaction product is evaporated to dryness at a temperature of 90°C and then put into a tray for crystallization, and then sent to a drying room for drying. The drying temperature is controlled at 100°C, and finally the finished product is obtained by pulverizing. By carrying out the analysis of nickel and threonine content to the finished product after the above reaction, and the structural analysis of conventional infrared analysis and X-ray diffraction, it is confirmed that the reaction product is the nickel threonine of the present...

Embodiment 3

[0033] This Example 3 prepares nickel threonine of the present invention through the following reaction steps: take 1250 kg of water and pour it into the reactor, turn on the stirring device, put 297.5 kg of threonine into the reactor at normal temperature, and then heat it to 55 ° C. Put 650.5kg 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 for crystallization, send it to a drying room for drying, the drying temperature is controlled at 105°C, and finally pulverize The nickel threonine finished product is prepared. By carrying out the analysis of nickel and threonine content to the finished product after the above reaction, and the structural analysis of conventional infrared analysis and X-ray diffraction, it is confirmed that the reaction product is the nickel threonine of the present invention, and the molecular formula of the finished product is:

Abstract

The invention discloses a threonine chelate named as nickel threonine, having the molecular structural formula of [(C4H9NO3)2Ni]SO4NiSO4.XH2O, wherein the value of X ranges from 0 to 12. The nickel threonine is obtained by mixing nickel sulfate or crystalline hydrate of the nickel sulfate with a threonine aqueous solution for reacting. The nickel threonine can be used as a feed additive for animals. The nickel threonine has simple application method and convenient operation and achieves very obvious feeding effect when used for feeding pigs, fowls and ruminants.

Description

technical field [0001] The invention belongs to the field of feed additives, in particular to a threonine chelate and its preparation method and application. Background technique [0002] Threonine is an important nutritional enhancer, which can strengthen the nutrition of grains, cakes, dairy products, etc. Threonine, like tryptophan, also has the functions of restoring human fatigue and promoting growth and development. In medicine, because the structure of threonine contains hydroxyl groups, it has a water-holding effect on human skin. After combining with oligosaccharide chains, it can play an important role in protecting cell membranes; threonine can also promote phospholipid synthesis and fatty acid oxidation in the body , and its preparation has medicinal effects such as promoting human growth and anti-fatty liver, and is often used as a component of compound amino acid infusion. At the same time, threonine is also the basic raw material for the manufacture of highl...
