Embodiment 1

[0046] A method for preparing ferrous valine, comprising the following steps: turning on stirring, adding 239.1Kg of valine with a purity of 98% to 2.2t water, turning on the stirring, and then adding 109.2Kg of sodium carbonate with a purity of 98%, After stirring until there are no more bubbles, add 171.7Kg of ferrous sulfate monohydrate with a purity of 96% and raise the temperature to 30°C, react for 2h. After the reaction, press filter and flash dry to obtain 301.8Kg of product.

[0047] In this example, the content of valine in the ferrous valine product is 73.7%, and Fe 2+ 16.0%, Fe 3+ It is 1.7%, the water loss rate at 180°C is 5.7%, the water loss rate at 104°C is 2.4%, that is, the purity is 97.1%, and the yield is 98.7% based on total iron, which is the molar ratio of valine to ferrous iron. About 2:1, the molecular formula is Fe(C 5 H 10 NO 2 ) 2 ·H 2 O. The powder diffraction pattern of ferrous valine obtained in this example is shown in figure 1 .

Embodiment 2

[0049] A method for preparing ferrous valine, comprising the following steps: turning on stirring, adding 239.1Kg of valine with a purity of 98% to 2.3t water, turning on the stirring, and adding 143.9Kg of potassium carbonate with a purity of 98%. After stirring until there are no more bubbles, add 249.4Kg of ferrous sulfate pentahydrate with a purity of 98% and raise the temperature to 40°C, add 0.37Kg of 10 mesh reduced iron powder, and react for 1.5h. After the reaction is complete, cool to Below 40°C, add 190L of ethanol to crystallize, centrifuge and dry in the oven to obtain 299.6Kg of product.

[0050] The content of valine in ferrous valine products is 74.6%, Fe 2+ 17.8%, Fe 3+ The water loss rate at 180°C is 5.8%, and the water loss rate at 104°C is 1.0%. The purity is 98.3%. The yield is 96.2% based on valine, which is the mole of valine and ferrous iron. The ratio is about 2:1, and the molecular formula is Fe(C 5 H 10 NO 2 ) 2 ·H 2 O.

Embodiment 3

[0052] A method for preparing ferrous valine, comprising the following steps: turning on stirring, adding 239.1Kg of valine with a purity of 98% to 2.0t water, turning on the stirring, and adding 173.1Kg of sodium bicarbonate with a purity of 98% After stirring until there are no more bubbles, add 280.9Kg of ferrous sulfate heptahydrate with a purity of 99% and increase the temperature to 45℃, add 0.28Kg of 40 mesh reduced iron powder, and react for 1.8h. After the reaction is completed, the reaction is completed and then cooled Below 40°C, add 420L of isopropanol and crystallize, centrifuge and flash dry to obtain 305.1Kg of product.

[0053] The content of valine in ferrous valine products is 74.1%, Fe 2+ 17.7%, Fe 3+ 0.1%, the water loss rate at 180°C is 5.7%, the water loss rate at 104°C is 2.0%, that is, the purity is 97.7%, and the yield is 97.4% based on valine, which is the mole of valine and ferrous iron The ratio is about 2:1, and the molecular formula is Fe(C 5 H 10 NO...

Abstract

The invention discloses a preparation method of ferrous valine. The method comprises the following steps: (1) adding valine into water, adding sodium carbonate / potassium carbonate, and stirring to react until no air bubbles emerge in order to obtain a valine salt solution; and (2) heating the valine salt solution, adding an inorganic ferrite, performing a reaction, carrying out solid-liquid separation after the reaction is finished, and drying to obtain the ferrous valine. The invention also provides an application of the ferrous valine as an animal feed additive in animals. The reaction is divided into two steps, the sodium carbonate / potassium carbonate is added into the valine solution and reacts to generate the valine salt, and then the valine salt reacts with the inorganic ferrite to obtain the product, so reaction side reactions are few, and the product purity is high.

Description

Technical field [0001] The invention belongs to the field of animal feed additives, and particularly relates to a preparation method and application of an amino acid chelate. Background technique [0002] The trace element iron is one of the essential trace elements for animals. Iron is an important part of hemoglobin. Iron is found in red blood cells that supply oxygen to muscles. It is also a component of many enzymes and immune system compounds. Iron can participate in the transport and storage of oxygen, promote development, increase resistance to diseases, regulate tissue respiration, prevent fatigue, form heme, prevent and treat anemia caused by iron deficiency, and make animal skin red and bright. . Animals consume most of the iron needed from food. It is generally believed in the art or related fields that animals hardly absorb and utilize trivalent iron. Currently known and reported iron elements absorbed and utilized by animals generally exist in the form of divalent...
