Abstract

The invention relates to an industrial production and preparation process of glycine chelated manganese. The industrial production and preparation process comprises the following steps: enabling manganese sulfate monohydrate and a sodium hydroxide solution to generate a manganese hydroxide white solid under certain conditions, filtering, drying, then adding sulfuric acid, dropping a glycine solution for reaction, concentrating for 2-4h when the vacuum degree of filtrate is above 0.07MPa after the end of reaction, adding 60-70 parts by weight of acetone into the solution and precipitating the solid; and performing centrifugal filtration, using a double-cone vacuum drying machine, and drying at the temperature of 80 DEG C for 2h-3h when the vacuum degree is above 0.06MPa to obtain a glycine chelated manganese product. The industrial production and preparation process provided by the invention has the advantages of simple synthesis route, safety and reliability of the process, short reaction period, high yield, good product quality and no production of pollutants.

Description

technical field [0001] The invention relates to a preparation process suitable for the industrial production of glycine chelated manganese. Background technique [0002] Trace elements are one of the essential nutrients for animals to maintain life and produce, directly participate in almost all physiological and biochemical functions of the body, and play an extremely important role in life activities. Trace element additives have gone through three stages of development: inorganic salt additives, simple organic matter and trace element amino acid chelates. Trace element amino acid chelate, as the third generation trace element, is regarded as an ideal trace element because of its good chemical stability, high biological effect, easy digestion, anti-interference, non-toxic and non-irritating properties. Elemental supplements. [0003] Manganese is one of the indispensable trace elements for animal growth, reproduction and a series of life activities, and plays an importan...
