Problems solved by technology

There are also reports to adopt glycine and ferrous sulfate heptahydrate in liquid medium, neutralize with calcium carbonate to carry out chelation reaction, obtain ferrous glycinate by processes such as impurity filtration, filtrate concentration, crystallization, and easily make ferrous under the neutralization condition of this method Oxidation of iron leads to high content of ferric iron, many process steps, and requires concentrated liquid, long reaction time and high energy consumption (Teng Jiaoqin et al., Synthesis and Analysis Method of Feed Grade Ferrous Glycinate)

Embodiment Construction

[0019] 1. Case 1 The molar ratio of glycine and ferrous sulfate heptahydrate is 1:1. Mix 3.8 grams of glycine and 15 grams of ferrous sulfate heptahydrate evenly, and let it stand overnight. Grind thoroughly with a mortar, stand for 2 hours, and dry at 60° C. to obtain 12.0 g of product. After testing, it contains 0.69% free glycine and 17.40% ferrous iron. The ferric iron content is 0.38%, the water content is 4.5%, and the total nitrogen content is 26.5%.

[0020] 2. Case 2. The molar ratio of glycine and ferrous sulfate heptahydrate is 1:1.05. Mix 3.8 grams of glycine and 15.75 grams of ferrous sulfate heptahydrate evenly and let it stand overnight. Further, it was fully ground with a mortar, left for 2 hours, and dried at 60° C. to obtain 12.5 g of the product. After testing, the content of free glycine is 0.78%, and the content of ferrous iron is 17.69%. The ferric iron content is 0.40%, the water content is 3.82%, and the total nitrogen content is 28.50%.

Abstract

The invention relates to a formula for preparing ferrous bisglycinate and a method thereof, which belongs to the technical field of preparing amino acid trace element chelates. The invention aims to realize industrial production with a simper process, and the industrial production has mild reaction condition, is green and environmental-friendly, has high yield and is suitable for being applied in feed additives. According to the invention, ferrous bisglycinate is compounded through solid-solid reaction. The formula for preparing the ferrous glycine sulfate comprises glycine and iron sulfate heptahydrate with the molar ratio of 1:1. The preparation method is simple and feasible, has no pollution in the process, is low in energy consumption and is worth of popularization.

Description

technical field [0001] The invention discloses a formula and method for preparing ferrous glycinate, belonging to the technical scope of preparing amino acid trace element chelates. Background technique [0002] Amino acid trace element chelate is a new type of feed additive formed by chemically chelating amino acid or short peptide substances and trace elements. In the late 1960s, this type of product was successfully developed abroad and applied in the breeding industry. In the mid-1980s, our country carried out the development and application research of this project, and made great progress. The research and application of amino acid trace element chelate has also been included in the national "Eighth Five-Year Plan" key research plan, which marks that my country's trace element nutrition research has entered the development path of amino acid chelate. [0003] The core advantage of metal element chelates is actually high biological value, which is specifically reflect...
