| titleOfInvention | Synthesis method of zinc methionine chelate |
| abstract | The invention relates to a method for synthesizing zinc methionine chelate, which comprises the following steps: putting glycerol and water into a reaction vessel, mixing and stirring, sequentially adding methionine, zinc salt and a catalyst in the stirring process, wherein the catalyst is one of sodium tartrate, sodium benzoate, sodium oxalate or sodium salicylate, and reacting for 0.5-6 hours under the conditions of 1-5 standard atmospheric pressures and a temperature of 105-250 ℃; after the reaction in the step A is finished, filtering while the solution is hot to obtain a filter cake, washing the filter cake with a proper amount of water, and drying and crushing the filter cake to obtain a zinc methionine chelate; the method divides the reaction which is difficult to occur originally into two easier steps, firstly, the glycerol and the zinc oxide react to obtain a certain intermediate, and then the intermediate reacts with the methionine to generate the zinc methionine, so that the yield of the reaction is high, and the wastewater containing the salt by-products is not generated. |
