Embodiment 1

[0024] A preferred embodiment of the present invention, the embodiment is by mixing nickel sulfate or nickel sulfate crystal hydrate with hydroxymethionine aqueous solution and strong base, and reacting at a reaction temperature of 50°C to 100°C and a reaction pH of 5 to 7 Under the condition of , react for 1.0h~2.5h to get the reaction product.

[0025] Through the basic principles and laws of chemical reactions, we can preliminarily determine that the reaction product may be a new hydroxymethionine chelate—nickel hydroxymethionine; by analyzing the content of nickel and hydroxymethionine in the reaction product after the above reaction , and conventional infrared analysis and structural analysis of X-ray diffraction, further confirmed that the reaction product is nickel hydroxymethionine of the present invention.

[0026] Wherein, the molar ratio of nickel sulfate or the crystal hydrate of nickel sulfate to hydroxymethionine is (0.8~1.1): 2, the molar ratio of nickel sulfate...

Embodiment 2

[0034] In Example 2, nickel hydroxymethionine of the present invention is prepared through the following reaction steps: Measure 100mL of water and pour it into a 250mL reaction cup, put 17.0g of hydroxymethionine into the reaction cup at room temperature, heat and stir, and then put 13.4g of six Nickel sulfate in water to make it fully dissolved, then add 4.0g sodium hydroxide to make the pH value of the reaction solution in the reaction cup to about 6.0, react at 85°C and normal pressure for 1h, and then filter the reaction product after cooling to room temperature. Then it was dried at 105°C for 6 hours, and finally crushed to obtain the finished product.

[0035] By carrying out the analysis of nickel, hydroxymethionine 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 hydroxymethionine of the present invention, and its molecular formula...

Embodiment 3

[0038] The present embodiment 3 prepares nickel hydroxymethionine of the present invention through the following reaction steps: take 800kg of water and pour it into the reactor, turn on the stirring device, put 204kg of hydroxymethionine into the reactor at normal temperature, heat and stir, and then put 164.8kg into it Fully dissolve nickel sulfate hexahydrate, then use 48.9kg sodium hydroxide to adjust the pH value of the reaction solution in the reactor to about 6.2, react at 88°C and normal pressure for 1.5h, and cool the reaction product to room temperature for pumping filtered, then dried at 108°C for 5.5 hours, and finally crushed to obtain the finished product.

[0039] By carrying out the analysis of nickel, hydroxymethionine 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 hydroxymethionine of the present invention, and its molec...

Abstract

The invention discloses a hydroxyl chelate methionine of which the name is hydroxyl nickel methionine and the molecular formula is (C5H9O3S)2Ni. The hydroxyl nickel methionine is obtained by mixing nickel sulfate or the crystalline hydrate of nickel sulfate with hydroxyl methionine solution and alkali for reaction, can be used as animal feed addictive for application, has simple application method and convenient operation, and gets obvious feeding effect after feeding swine, poultry and ruminants.

Description

technical field [0001] The invention belongs to the field of feed additives, in particular to a hydroxymethionine chelate and its preparation method and application. Background technique [0002] Methionine is an important essential amino acid for protein synthesis. It mainly exists in animal protein and less in plant protein. Methionine cannot be directly synthesized in the body or the synthesis speed cannot meet the needs of animals, so it can only be supplemented by exogenous sources to meet the needs of animals for methionine. Methionine is the first limiting amino acid in corn-soybean meal-based diets for poultry, the first limiting amino acid for milk and milk protein synthesis in high-yielding dairy cows with corn as the main basal diet, and the second limiting amino acid for pigs. When the methionine in the feed is lacking, the livestock and poultry will show poor growth and development, weight loss, damage to liver and kidney functions, muscle atrophy, rough and du...
