Preparation and use of crystal basic copper chloride containing iron

Abstract

The invention discloses a preparation method of ferrous crystalline caustic soda type copper chloride, and the function thereof, wherein, the preparation method comprises the steps of: a. taking and preheating an ammonium chloride solution, a ferrous copper chloride solution and hartshorn or copper chloride ammonia liquor respectively; b. putting the preheated ammonium chloride solution, the ferrous copper chloride solution and the hartshorn or the copper chloride ammonia liquor in a reaction container to carry out synthetic reaction to generate the ferrous crystalline caustic soda type copper chloride; and c. stopping charging when the ferrous crystalline caustic soda type copper chloride grows certain grain diameter, discharging part of the material from the bottom, discharging the precipitate in the material, washing, filtering and centrifugalizing the material to obtain the ferrous crystalline caustic soda type copper chloride. The ferrous crystalline caustic soda type copper chloride prepared by the method can be used as the copper-iron micronutrient element additive of animal feed and is characterized by moisture resistance, no agglomeration, good fluidity, stable chemical property, easy mixing with feed, low price, low additive cost, soluble subacidity, easy absorption and utilization, and the like.

Description

【Technical field】 [0001] The invention relates to a preparation method of a compound, in particular to a preparation method and application of an iron-containing crystalline basic copper chloride that can be used as an additive of copper and iron micronutrient elements for animal feed. 【Background technique】 [0002] Copper element can participate in the hematopoietic function of the body, and plays an important role in the synthesis of heme and the maturation of red blood cells. In animals, copper is mainly used as an essential component of various enzymes to participate in the bone formation process of animals, the pigmentation and keratinization of hair and fur. Copper element also has a very close relationship with animal reproduction. It is a micronutrient element that must be added to animal feed. As an animal nutritional supplement and growth promoter, it has been widely used in animal husbandry at home and abroad. Basic copper chloride is a copper compound, which is...

Problems solved by technology

[0005] Chinese patent 95192983.6 discloses a "micronutrient additive". In the method for synthesizing atacamite type basic copper chloride (atacamite) provided by it, it is difficult to control the thickness of crystal particles generated due to the instability of the reaction system, and the reaction The time is as long as 8 hours, resulting in low production efficiency

No. 200610060144.1 Chinese patent discloses a "preparation method and application of botallackite". Although the reaction system is relatively stable and the production efficiency is high, the botallackite generated is a crystal with a large particle size, and the particles are distributed in the 30 to 300 microns, and too large particles are not conducive to the absorption and utilization of passive objects as feed additives, and the control of reaction parameters in the production process of botallackite type basic cupric chloride is strictly required, otherwise the product is easy to agglomerate during transportation and storage , difficult to mix evenly with other mineral components
