Embodiment 1

[0039] A manganese cystine (molecular formula is C 6 h 10 N 2 o 4 S 2 Mn H 2 O) preparation method, comprises the following steps:

[0040] Turn on stirring, at 2m 3 Add 400L of 95% ethanol to the water, then add 218.5Kg of sodium carbonate with a purity of 98%, add 490.4Kg of cystine with a purity of 98% after stirring and dissolving, stir at room temperature until no more bubbles emerge, then heat up to 70°C, add 348.4 Kg of manganese sulfate monohydrate with a purity of 98% was reacted for 1 hour. After the reaction was completed, the reaction system was cooled to room temperature, crystallized, filtered, and flash-dried to obtain 606.7 Kg of manganese cystine.

[0041] The measured content of cystine in manganese cystine products is 75.5%, Mn 2+ It is 17.4%, the dehydration rate at 180°C is 5.7%, and the dehydration rate at 104°C is 1.2%, that is, the purity is 98.6%, and the yield is 96.1% in terms of cystine, which is the ratio of cystine and manganese. The molar...

Embodiment 2

[0043] A manganese cystine (molecular formula is C 6 h 10 N 2 o 4 S 2 Mn H 2 O) preparation method, comprises the following steps:

[0044] Turn on stirring, at 2.5m 3 Add 310L of propanol to the water, then add 349.7Kg of sodium bicarbonate with a purity of 98%, then add 8.4L of propenyl alcohol, stir and dissolve, add 490.4Kg of cystine with a purity of 98%, and stir at room temperature until no more bubbles appear. After leaving, heat up to 60°C, add 341.5Kg of manganese sulfate monohydrate with a purity of 98%, and react for 1.8 hours. After the reaction is completed, cool the reaction system to room temperature, crystallize, press filter, and flash dry to obtain manganese cystine 640.8 Kg.

[0045] The measured content of cystine in manganese cystine products is 72.8%, Mn 2+ It is 16.8%, the water loss rate at 180°C is 5.5%, and the water loss rate at 104°C is 4.8%, that is, the purity is 95.1%, and the yield is 98.9% in terms of manganese, that is, the molar rati...

Abstract

The invention discloses a preparation method of cystine manganese. The preparation method comprises the following steps: starting stirring, adding carbonate into an organic solvent-water solution, stirring for dissolving, adding cystine, stirring until no bubbles come out, heating, adding a manganese source, performing a reaction, and cooling, crystallizing, filtering, washing and drying the obtained reaction system after the reaction is finished in order to obtain the cystine manganese. The invention also provides an application of the cystine manganese as an animal feed additive in animals.The reaction is divided into two steps, the carbonate is added into a cystine solution and reacts to generate a cystine salt, then the cystine salt reacts with an inorganic manganese salt to obtain the product, and a reaction under a strong base and a high temperature can be avoided by adopting the two steps of reaction, so cystine is not prone to undergoing side reactions, and the product purityis high.

Description

technical field [0001] The invention belongs to the field of feed additives, in particular to a preparation method and application of an amino acid complex. Background technique [0002] Manganese is a component of arginase, prolinease, RNA polymerase, manganese-containing superoxide dismutase (Mn-SOD), pyruvate carboxylase, etc. It is also a component of many enzymes in the body such as phosphorylase, aldolase Activator of enzymes, transferases, hydrolases. Manganese deficiency in animals can lead to reduced feed intake, slowed growth, reduced feed utilization, bone abnormalities, ataxia and abnormal reproductive function. [0003] Cystine assists in skin formation and is important for detoxification. Cystine protects cells from copper poisoning by reducing the body's ability to absorb copper. When it is metabolized, it releases sulfuric acid, which reacts chemically with other substances to increase the detoxification function of the entire metabolic system. In addition...
