Embodiment Construction

[0023] The following examples are further explanations and illustrations of the present invention, and do not constitute any limitation to the present invention.

[0024] One, the preparation of iron-containing crystalline basic copper chloride:

[0025] Get 400 kg of industrial grade solid ammonium chloride and add it to 8M 3 In the FRP reaction tank, inject 1500 liters of tap water, stir while passing steam to dissolve ammonium chloride and preheat to 75°C, add a small amount of water to 2M 3 . In addition, the refined acidic copper chloride etching waste liquid with a copper ion content of 100 g / L, an iron ion content of 1300 mg / L, and a pH value of 2 and 6% ammonia water were each 3.0M 3 , respectively preheated to 75°C in their respective raw material storage tanks. Start the stirring paddle of the reaction tank, and simultaneously turn on the raw material pumps of copper waste liquid and ammonia water and adjust the flow rate of the flow meter so that the two are adde...

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...
