Problems solved by technology

Although sodium selenite is generally added in feed, the situation of selenium deficiency is still quite frequent. The biological potency of sodium selenite is low, and the range between the poisoning amount and the required amount is small. Because of its strong toxicity, it is difficult for production and production. Use brings a lot of inconvenience
On the one hand, inorganic selenium is absorbed through the intestinal wall by passive diffusion, then enters the liver, and then converted into biological selenium, the bioavailability is low, and a large amount of unused inorganic selenium is discharged into the environment, causing serious environmental pollution; on the other hand , the dosage of inorganic selenium is difficult to control, and it is easy to cause poisoning, so its usage is limited. Japan even prohibits the addition of sodium selenite

Embodiment 1

[0012] The liquid chlorine is vaporized, dried and reacted with 160g of selenium powder to generate selenium dichloride, and the selenium dichloride reacts with chlorine, dried and pulverized to obtain 405g of selenium tetrachloride.

[0013] Dissolve 1180g of methionine in water, add lye to react, concentrate and dry to obtain 1270g of methionine salt.

[0014] Add 1270g of methionine salt and 405g of selenium tetrachloride into water to react, the reaction pH is controlled at 6-7, the reaction temperature is 5°C, and the reaction time is 2 hours. The reactant is filtered and concentrated, then dried and pulverized to obtain methionine selenium Product 1170g.

Embodiment 2

[0016] Liquid chlorine is vaporized, dried and reacted with 80g of selenium powder to generate selenium dichloride. The unreacted selenium powder can be separated and removed through a microporous membrane, and returned to continue to participate in the reaction. Selenium dichloride reacts with chlorine, dried and pulverized to obtain Selenium tetrachloride 215g.

[0017] Dissolve 590 g of methionine in water, add lye to react, concentrate and dry to obtain 635 g of methionine salt.

[0018] Add 635g of methionine salt and 215g of selenium tetrachloride into isopropanol for reaction, the reaction pH is controlled between 5-7, the reaction temperature is 20°C, and the reaction time is 3 hours. The reactant is filtered and concentrated, and then dried , pulverized to obtain 605g of methionine selenium product.

Abstract

The invention is a preparing process of novel organic selenium-methionine selenium, and its characteristic: the process of the methionine selenium product includes the working procedures of selenium dichloride synthesis, selenium tetrachloride synthesis, methionine salt synthesis, methionine selenium synthesis, drying, crushing, etc, and the novel methionine selenium has high biological utilization ratio, low toxicity, improves the oxidation resistance and immune function of the organism and regulates internal secretion by enhancing the activity of glutathione peroxidase in tissue cells and plays a remarkable role in oxidation resistance, immune efficiency of body fluid, promoting the growth of domestic fowls and animals, improving quality of muscles, etc.

Description

technical field [0001] The invention relates to a preparation process of a novel organic selenomethionine selenium. Background technique [0002] Nutritionists have confirmed that selenium is one of the essential trace elements for the human body. Selenium can promote human growth and development, regulate human body functions, enhance disease resistance, prevent and treat Keshan disease, Kaschin-Beck disease and more than 40 kinds of diseases. It has anti-aging, Anticancer effect. [0003] Selenium is one of the indispensable trace elements in the growth of animals, especially mammals. More than two-thirds of the regions in my country are selenium-deficient regions. The average selenium content in the forage grass produced in these regions is lower than 0.05mg / kg , Serious selenium-deficient areas accounted for 29%. The fodder and grass in these areas are processed into compound feed, and the selenium content is seriously insufficient. Selenium deficiency in animals will ca...
