Problems solved by technology

In general, these methods have the following disadvantages: (1) hydriodic acid is a strong acid, and the cost of transportation and storage is high, and more importantly, there is a potential safety hazard, and the price of hydriodic acid is high, which is unfavorable for large-scale production (2) Synthetic ethylenediamine dihydroiodide by hydroiodic acid, because of containing excessive iodine is adsorbed on the surface of synthetic product, and this product appears yellow, and purity is relatively poor
However, it is not a full pressure reaction in the synthesis conditions, which will have a certain impact on the yield, purity and color of the product

Embodiment 1

[0034] A 1L small high-pressure reactor is selected as the main reactor, which consists of a kettle cover, a kettle body, a strong magnetic coupling stirrer, a high temperature and high pressure needle valve, a pressure instrument, a lower stirring part, an internal cooling coil, a temperature measuring part, a liquid pipe, etc. System Components.

[0035] This reaction is to generate hydrogen iodide on the surface of the catalyst through hydrogen and iodine under the action of the catalyst, and the hydrogen iodide is neutralized with ethylenediamine acid base to obtain ethylenediamine dihydroiodide.

[0036] Steps:

[0037] (1) Install the reaction instrument, add 50g of iodine elemental substance, 9.67g of ethylenediamine (theoretical calculation value), and 0.25g of platinum black catalyst into a 1L small-scale high-pressure reactor; Therefore, the quality of ethylenediamine actually dropped into the reactor is greater than 9.67g.

[0038] (2) Control the temperature of t...

Embodiment 1

[0052] Table 1 shows the test results of ethylenediamine dihydroiodine on the milk production performance of lactating dairy cows in Example 1. The result of table 1 shows, from the milk yield of lactating cow during 1-15 days, add 2.0mg / kg ethylenediamine dihydroiodine than control group high 17.20%, and add 2.0mg / kg potassium iodide group Milk production increased by 4.70%; From the perspective of milk production of lactating cows during the 16-30 days, adding 2.0mg / kg ethylenediamine dihydroiodide increased by 9.70% compared with the control group, while adding 2.0mg / kg The milk yield of the potassium iodide group has increased by 6.40%; combined with the milk production performance of 1-15 days and 16-30 days, it is shown that the ethylenediamine dihydrogen iodide prepared by this embodiment can effectively improve the milk production of lactating cows than potassium iodide quantity.

Embodiment 2

[0060] A 1L small high-pressure reactor is selected as the main reactor, which consists of a kettle cover, a kettle body, a strong magnetic coupling stirrer, a high temperature and high pressure needle valve, a pressure instrument, a lower stirring part, an internal cooling coil, a temperature measuring part, a liquid pipe, etc. System Components.

[0061] This reaction is that hydrogen and iodine generate hydrogen iodide on the surface of the catalyst under the action of the catalyst, and the hydrogen iodide is neutralized with ethylenediamine acid and alkali to obtain ethylenediamine dihydroiodide.

[0062] Steps:

[0063] (1) Install the reaction instrument, add 50g of iodine elemental substance, 9.67g of ethylenediamine (theoretical calculation value) and 0.4g of platinum black catalyst into a 1L small-scale high-pressure reactor; Therefore, the quality of ethylenediamine actually dropped into the reactor is greater than 9.67g.

Abstract

The invention discloses a preparation method of ethanediamine dihydroiodide, which includes steps of (1), preparation of raw materials; (2), synthesis of ethanediamine dihydroiodide: adding iodine elementary substance, ethidene diamine and platinum black catalyst in a pressure reaction kettle; controlling temperature from 50 to 60 DEG C; replacing air in the reaction kettle by nitrogen, and then charging hydrogen under the continuous stirring; preserving temperature under 1.5-2.5 MPa and stirring; releasing pressure and adding alcohol, filtering platinum black catalyst to obtain filter fluid;placing the obtained filter fluid in a crystalizing tank, slowly stirring and adding ice salt water; crystalizing for 15-24 hours at 0-5 DEG C; finishing the reaction; (3), filtering and separating the fluid in the crystalizing tank and then performing vacuum drying to obtain ethanediamine dihydroiodide powder. The preparation method can improve product yield, purity and color, and reduce environmental pollution; the prepared ethanediamine dihydroiodide is added in the lactation cow feed as the additive, thus the lactation ability of a cow is improved.

Description

technical field [0001] The invention relates to the field of feed additive production, in particular to a preparation method of ethylenediamine dihydroiodide and its application in feed additives. Background technique [0002] The trace element iodine plays an important physiological role in the life activities of animals. Generally speaking, the average iodine content in animals is 50-200 μg / kg, but this value varies widely, and the main determinant is the iodine content in the animal's diet. Iodine realizes its physiological function in the animal body, mainly by affecting the synthesis of thyroxine to realize its physiological function, including regulating and maintaining the heat balance in the body, affecting the growth and development of animals, affecting animal reproductive performance and affecting the condition of animal fur, etc. . The absorption of iodine is mainly concentrated in the small intestine and stomach of monogastric animals, and the main absorption ...
