Problems solved by technology

[0004] There are few methods for synthesizing copper glycinate in the prior art, and the existing synthesis methods for copper glycinate have relatively high conditions, high requirements for initiators, and industrial synthesis steps are quite cumbersome and difficult to operate
In addition, when the traditional hot water bath method is used to synthesize copper glycinate, a complex-[Cu(OH) 4 ] 2 -, which to some extent leads to the waste of copper ions

Abstract

The invention provides a novel simpler method for synthesizing copper glycine, comprising the following steps of: 1, respectively porphyrizing equimolar CuSO4.5H2O and K2CO3, mixing and grinding; 2, rapidly pouring the above mixture into 50mL of warm water, rapidly stirring, and letting the two substances fully react; 3, filtering or precipitating to obtain basic cupric carbonate; 4, mixing the basic cupric carbonate powder and a glycine solution according to the mole ratio of 1: 4.5 in a water bath of 65-70 DEG C; and 5, stirring and chelating for about 30 minutes. The method provided by the invention requires simple steps and has high chelating rate. When the substances are added into the hot water bath, the reaction is immediately performed. It only takes 30min to chelate to the maximum value. In addition, the yield is high.

Description

technical field [0001] The invention relates to a preparation method of copper glycinate, in particular to a basic copper carbonate chelation method for preparing copper glycinate. Background technique [0002] Amino acids and copper ions are essential nutrients for humans and animals. Among them, copper is an indispensable trace element in the human body, directly or indirectly participates in almost all physiological and biochemical functions of the body, and plays an extremely important role in life activities. Amino acids are the basic structural units of proteins, such as glycine, aspartic acid and lysine are all natural amino acids necessary for life. [0003] Amino acid trace element chelate is a new generation of nutritional preparation currently developed, which can not only fully meet the needs of living organisms for trace elements, but also achieve the double effect of supplementing amino acids. As a combination of amino acid and copper, copper glycinate can pl...
