Embodiment 1

[0019] Add 11.6g of fumaric acid, 85mL of deionized water and 15mL of ammonia water with a mass fraction of 25% to 28% in a 100mL beaker to make the pH value around 5, mix well, filter to remove trace incompatible substances, and set aside.

[0020] Add 28.76g of zinc sulfate heptahydrate into a 250mL flask, then transfer the prepared ammonium fumarate solution into a 250mL flask, stir for 50min, and filter with suction. Stir and wash with 100mL deionized water for 10min, filter with suction, and dry at 60°C for 6h to obtain zinc fumarate product. The test results are shown in Table 1.

Embodiment 2

[0022] Add 118g of succinic acid, 852mL of deionized water and 148mL of ammonia water with a mass fraction of 25% to 28% in a 1000mL beaker, so that the pH value is around 5, mix well, filter to remove trace impurities, and set aside.

[0023] Add 166g of calcium chloride dihydrate into a 2000mL beaker, then transfer the prepared ammonium succinate solution to a 2000mL flask, stir for 1 hour, and filter with suction. Stir and wash with 500mL deionized water for 15min, filter with suction, and dry at 70°C for 6h to obtain the calcium succinate product. The test results are shown in Table 1.

Embodiment 3

[0025] Add 13.4g of malic acid, 85mL of deionized water and 15mL of ammonia water with a mass fraction of 25% to 28% in a 100mL beaker to make the pH value around 5, mix well, filter to remove trace incompatible substances, and set aside.

[0026] Add 14.7g of calcium chloride dihydrate into a 250mL flask, then transfer the prepared ammonium malate solution into a 250mL flask, stir for 40min, and filter with suction. Stir and wash with 100mL deionized water for 10min, filter with suction, and dry at 70°C for 6h to obtain calcium malate product. The test results are shown in Table 1.

Abstract

The invention discloses a preparation method of an organometallic salt additive, comprising the following steps: (1) using short-chain organic acid as an acid source and ammonia water as an alkali source, and mixing the short-chain organic acid and the ammonia water in an aqueous solution to prepare organic ammonium salt; and (2) mixing an iron source or a calcium source or a zinc source with thesolution obtained in the step (1), stirring, filtering, washing and drying to obtain the high-purity organometallic salt additive. The organometallic salt disclosed by the invention has a better crystal structure and higher purity, the used raw materials are wide in source and low in price, the problems of complex process, high production cost, low yield and the like in the prior art are better solved, and the organometallic salt additive has a good industrial application prospect.

Description

technical field [0001] The invention relates to a preparation method of an organic metal salt additive, belonging to the field of feed additives and pharmaceutical additives. Background technique [0002] Metal elements are essential elements in animals, such as calcium, zinc, iron, etc., which have the functions of strengthening bones, regulating appetite, improving the secretion function of the digestive system, and enhancing the immune function of animals. Compared with inorganic metal element additives, organometallic element additives have the characteristics of high efficiency, low toxicity, low pollution, and easy absorption. The short-chain organometallic salt, as an organometallic element additive with extremely high metal element content, is beneficial to the absorption of calcium, zinc, and ferrous ions by animals and humans. At the same time, short-chain organic acid ions can participate in the tricarboxylic acid cycle to form ATP to provide energy for the metab...
