Abstract

The invention relates to a production method and device of a novel green and environment-friendly methionine hydroxyl analogue complex metal salt, and the method comprises the following steps of: (1)adding a methionine hydroxy analogue and water into a reaction device, heating and stirring to obtain a 2-Hydroxyl-4-Methylthiobutyric acid aqueous solution; (2) adding a trace element metal salt intothe aqueous solution obtained in the step (1), and heating to completely dissolve to obtain a methionine hydroxy analog complex metal salt solution; and (3) adding a carrier to the aqueous solution obtained in the step (2), stirring uniformly, and drying to a constant weight to obtain a powdery methionine hydroxy analog complex metal salt product. The production method has the characteristics ofno three wastes, no dust pollution, no need of an alkali to adjust pH, no need of initiator, simple operation, easy maintenance of equipment, high yield, high product stability, low production cost, suitability for preparation of various trace element products and the like.

Description

technical field [0001] The invention belongs to the field of preparation of organic complexes, in particular to a novel green and environment-friendly production method and device for complexed metal salts of methionine hydroxyl analogues. [0002] technical background [0003] Trace elements zinc, ferrous iron, copper, manganese, cobalt, nickel and chromium (Ⅲ) are closely related to the life activities of animals, and are indispensable nutrients with less demand, so trace element products are a very important Nutritional additives, the traditional trace element additives commonly used in feed and premix are mainly inorganic salts such as sulfates, chlorides, oxides, etc. They have many defects, such as: in animal nutrition due to the chemical The reaction is complicated, and it is easily affected by phosphate, phytic acid and other ingredients in the feed, forming insoluble precipitates, which reduces the biological potency and affects the absorption and utilization; variou...
