Problems solved by technology

Although copper sulfate has the advantage of low price, it also has many substantial defects: 1. It has high water solubility and is very easy to absorb water, so it is easy to be damp and agglomerated, and it is easy to harden and corrode processing and production equipment
2. It has a strong oxidation effect and is easy to be reduced, which can destroy the vitamins in the feed and lead to fatty acid spoilage, thus destroying the nutritional content of the feed to a certain extent
3. The absorption and utilization rate of copper sulfate is low, and it has an antagonistic effect on the absorption of other trace elements, such as iron and zinc, which greatly reduces the normal absorption of trace elements in feed, and affects the normal metabolism and biological function of animals. Utilization
4. When used in large quantities, the soluble copper content in animal feces is high, and when discharged in large quantities, it will bring great pollution to the environment, especially water bodies
However, the spectroscopic study of basic copper chloride shows that in the crystal structure of basic copper chloride, the hydrogen bond strength in the basic copper chloride and paratacamite is greater than that of botallackite, so the botallackite The physical and chemical properties of copper ore are not as stable as that of chloride and paratacamite, and the moisture resistance and agglomeration and the storage period of the product are not as good as the two

Abstract

The invention provides a preparation method and applications of a copper oxychloride isomeride. The copper oxychloride isomeride is paratacamite. The preparation method comprises following steps: a chloride aqueous solution is prepared; botallackite and water are delivered into a reactor, and the chloride aqueous solution is added so as to form a reaction system; the reaction system is heated, pH value and reaction time of the reaction system are controlled so as to obtain paratacamite precipitate. Paratacamite prepared via the preparation method is taken as a feed nutritional additive; stability of crystals of the paratacamite is excellent; a problem of copper oxychloride product caking is solved; and great convenience is provided for product storing and application.

Description

technical field [0001] The invention relates to the production and utilization technology of basic cupric chloride, in particular to a preparation method and use of paratacamite, an isomer of basic cupric chloride, and belongs to the technical field of basic cupric chloride preparation . Background technique [0002] In the animal breeding industry, copper is a trace element necessary for animal growth. It plays an important role in maintaining the normal physiological metabolism of the animal body and improving immunity. It can participate in the synthesis of heme and the maturation of red blood cells. Osteogenesis, pigmentation and keratinization of hair and fur. A large number of feeding data prove that the addition of copper can improve the growth rate of animals, the daily food intake and promote the refinement and high quality of the feed. [0003] As the most important and first developed copper additive, copper sulfate has long been the most common source of copper...
