Description
Technical Field
The invention relates to a preparation method of an organic metal salt additive, belonging to the field of feed additives and medicament additives.
Background
The metal elements are essential elements in animal body, such as calcium, zinc, iron, etc., and have effects of strengthening bone, regulating appetite, improving digestive system secretion function, and enhancing animal body immunity. Compared with inorganic metal element additives, the organic metal element additives have the characteristics of high efficiency, low toxicity, low pollution, easy absorption and the like. The short-chain organic metal salt is used as an organic metal element additive with extremely high metal element content, and is beneficial to the absorption of calcium, zinc and ferrous ions by animals and human bodies. Meanwhile, short-chain organic acid radical ions can participate in tricarboxylic acid cycle to form ATP to provide energy for metabolism of organisms, and can also be used as a carbon skeleton to form amino acid to further synthesize protein. Therefore, researchers have increasingly strengthened research on the organometallic salt additives.
Zinc fumarate has been The first concern of researchers because of its high zinc content (Gupta M P, Sahu R D, MaulikP R. The crystalline structure of zinc (II) fumarate hydrate [ J]Zeitschriff ü r Kristallographie, 1983, 163(1-2): 151-154.) since then, researchers developed a grinding method to prepare zinc fumarate (Yang bin. microwave radiation solid phase method to synthesize zinc fumarate [ J bin ]]Application chemical, 2005 (9); tomislav Fri š č i ć, L a szl Louvbi, mechanical conversion of a metal oxide polymerization and pore frame using liquid-assisted formation (LAG) J]CrystEngComm, 2009, 11.). However, this method is gradually abandoned because it is difficult to realize industrial production. Instead, there is the sodium carbonate process (Xie Hong Zhen et al. Synthesis and crystallization of Zn (H)2O)4(C4H2O4)]·H2O[J]Journal of coding Chemistry,2003, 56(15): 1291-1297; zhoujian-zinc fumarate complex, its preparation and application, China 201710723397.0P]The method for catalytically synthesizing the zinc fumarate [ J ] by using maleic anhydride and maleic anhydride in one kettle (Jianyi, maleic anhydride in one kettle)]Shanghai chemical industry (10): 14-16.) and zinc hypoxide process (Method for synthesizing zinc fumarate as feed additive from zinc hypoxide, China 201010223550.1P]A new process for preparing zinc fumarate or calcium fumarate (Shesxin, etc.; Chinese 201110339486.8P].) and zinc acetate process (Bats J W et al, One-dimensional zinc (II) fumarate complexation polymers [ J W et al]Journal of coding Chemistry 2015, 68(1): 118-129.), and the like. With the development of zinc fumarate preparation process, the growth research of zinc succinate (Zhang GJUN, et al, non-linear optical crystal zinc succinate [ J)]The artificial crystal bulletin, 2008(06), 189-193), zinc lysine (Ronchi, etc., a preparation method and application of zinc lysine feed additive with medium chelating strength, China, 201610237068.0 [ P ]]) Preparation method of lysine chelated calcium with scallop shell as calcium source, China, 201710002171.1 [ P ]]) Chinese iron malate (Liyungzheng, a method for producing ferrous malate: 201810774797.9 [ P ]]) The preparation process of the organic metal salt is also developed successively. However, most of the existing processes for preparing the organic metal salt have the defects of low yield, easy corrosion equipment, complex process and the like, and the direction is pointed for the research of the subsequent organic metal salt additive production process.
