Problems solved by technology

These traditional chemical synthesis methods are often carried out in solution or in the gas phase, and are increasingly being rejected due to the limitations of high energy consumption, long time, serious environmental pollution, complex process, and high production cost.
However, the solid-phase synthesis method that meets the requirements of energy-saving and efficient green production has not been disclosed in patent documents and related technical journals.

Embodiment 1

[0035] Example 1 Glycine and zinc acetate and glycine and copper acetate ball milling prepare zinc glycinate and copper glycinate. The reaction principle is:

[0036] 2NH 2 CH 2 COOH+Cu(Ac) 2 ·H 2 O→[Cu(NH 2 CH 2 COO) 2·H 2 O]+2HAc↑

[0037] 2NH 2 CH 2 COOH+Zn(Ac) 2 ·H 2 O→[Zn(NH 2 CH 2 COO) 2 ·H 2 O]+2HAc↑

[0038] The preparation steps are as follows: wash the ball milling tank and ball milling beads, and dry them in an oven; weigh glycine and copper acetate to make the molar ratio 2:1, weigh glycine and zinc acetate to make the molar ratio 2:1; add two Carry out ball milling in a ball mill tank with a rotating speed of 55r / min; after ball milling, glycine and copper acetate turn into a blue solid, with a small amount of water generated, and have a pungent smell of acetic acid; after ball milling, glycine and zinc acetate become a white solid with a small amount of Moisture is formed, and there is a pungent acetic acid smell; the ball milling time is 1.5h an...

Embodiment 2

[0043] Example 2 Glycine and zinc sulfate and glycine and basic copper carbonate prepare zinc glycinate and copper glycinate. The reaction principle is:

[0044] 2NH 2 CH 2 COOH+CuCO 3 ·Cu(OH) 2 ·H 2 O→[Cu(NH 2 CH 2 COO) 2 ·H 2 O]+3H 2 O+CO 2 ↑

[0045] 2NH 2 CH 2 COOH+ZnSO 4 5H2O→[Zn(NH 2 CH 2 COO) 2 ·H 2 O]+H 2 SO 4

[0046] Described glycine and basic copper carbonate and glycine and zinc sulfate prepare the steps of glycinate copper and glycinate zinc as follows: wash ball mill jar, ball milling beads, dry with oven; weigh glycine and basic copper carbonate, make its molar ratio be 4 : 1, weigh glycine and zinc sulfate, make its mol ratio be 2: 1; Add in two ball mill jars respectively and carry out ball milling with rotating speed as 55r / min; Glycine and basic copper carbonate ball mill become blue solid, have A small amount of water is formed; glycine and zinc sulfate become white solid after ball milling, and a small amount of water is formed, but t...

Abstract

The present invention is a method of preparing the copper, zinc glycine complex with the ball-milling solid phase. The steps of the preparation are as follows: the glycine and copper, zinc metal compound are mixed in the ball-milling machine at the room temperature; the ball-milling machine is started; the rotation speed is 50 to 60 rounds per minute; the ball-milling time is 1.2 to 2 hours; the products are washed with the ethanol of 75 percent and are finally dried; the products are first dried at the room temperature and then fully dried at the temperature of 80 DEG C. The present invention has the simple process, the short reaction time, the high production and the low energy consumption; the method can not only effectively avoid the hard agglomeration of the products, but also have no use of the solvent the small environmental pollution. Besides, the content of copper and zinc is relatively high; the results are safe and reliable. The invention realizes the production of the feed additive with the copper and zinc glycine complex of the low cost and is the real green chemical reaction.

Description

technical field [0001] The invention relates to the field of synthesis and production of amino acid metal complexes, in particular to a method for preparing copper and zinc glycine complexes in solid phase by ball milling. Background technique [0002] Copper and zinc are essential trace elements for the human body, poultry and livestock and other animals. They exist in humans and animals in the form of proteins and metalloenzymes, which can accelerate growth and development, improve taste, regulate the body, immunity, prevent infection and promote wound healing, etc. Function. Therefore, copper and zinc should be added to the feed for normal growth of animals. For a long time, trace elements such as zinc and copper have been added to compound feed in the form of sulfate. The existence of sulfate not only easily causes corrosion to feed processing equipment and affects the stability of vitamins, but more seriously, a large amount of sulfate is After animal ingestion, it wi...
