[0033] A preparation method of a composite product of mineral trace elements and taurine, comprising the following steps:
[0034] Step 1: Dissolving taurine in an aqueous solution to obtain a taurine solution is placed in a reaction container; the mass concentration of taurine in the taurine solution is 5wt.%˜50wt.%.
[0035] Step 2: Add metal salts corresponding to metal mineral elements to the taurine solution obtained in step 1 and mix thoroughly; fully react at 50-200°C; mix by stirring method, the stirring method is mechanical stirring, magnetic stirring , artificial stirring, ultrasonic stirring, vibration stirring; the reaction time is 3 ~ 10h. It is heated to the required temperature by one of heating rod heating, infrared heating, and high-frequency electromagnetic heating.
[0036] Step 3: Taurate coordination polymer can be obtained by removing volatile substances from the reaction product of step 2; the volatile substances are removed through a vacuum distillatio...

[0043] A preparation method of a composite product of mineral trace elements and taurine, comprising the following steps:
[0044] Step 1: dissolving 3 mol of taurine in an aqueous solution to prepare a taurine solution with a taurine concentration of 50 wt.%, and placing it in a reaction vessel.
[0045] Step 2: Add 1mol MgCl to the taurine solution obtained in step 1 2 , heated to 70°C in the reaction vessel for 10h to generate a magnesium taurate solution; then add 1mol K to the solution 2 CO 3The weak alkaline solution reacted for 1h, due to the alkaline environment, part of the magnesium taurate formed a magnesium taurine complex.
[0046] Then continuously add 1mol nickel acetate solution and catalytically active 1MnCl through peristaltic pump 2 And after mechanical stirring, use high-frequency electromagnetic heating to 150°C, and keep warm for 10h.
[0047] Step 3: The taurate coordination polymer can be obtained from the volatile matter of the reaction product in ...
