Abstract

The invention discloses a method for preparing B type basic copper chloride catalyzed and weathered by an acid and application thereof. The method comprises the following steps that: a, B type crystallized basic copper chloride is added into a mixing vessel, the mixing vessel is started, and the temperature in the mixing vessel is maintained to be between 30 and 100 DEG C; b, the acid is added in a spraying mode through a liquid adding device of the mixing vessel during the operation of the mixing vessel, and the spraying time is between 5 and 60 minutes; and c, the B type crystallized basic copper chloride and the acid are mixed for 5 to 100 minutes, and then the obtained product is naturally cooled to the normal temperature in the mixing vessel to obtain catalyzed and weathered crystallized basic copper chloride. The B type basic copper chloride catalyzed and weathered by the acid prepared by the method can be used as an animal feed additive. The B type basic copper chloride catalyzed and weathered by the acid has the characteristics of having better stability, not agglomerating when stored for a long time, refining particles, containing partial organic copper, being more favorable for the absorption and utilization of animal bodies, 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 acid-catalyzed weathering B-type basic copper chloride. 【Background technique】 [0002] Copper is a micronutrient that must be added to animal feed. Chinese patent 200610060144.1 discloses a method for preparing B-type (Botallachite) crystalline basic copper chloride. The B-type crystalline basic copper chloride prepared by this method has good fluidity because it is insoluble in water but easily soluble in weak acid solution. , easy to feed compounding, almost no catalytic oxidation of vitamins and lipids in feed, high bioavailability of copper, small amount of growth-promoting addition, which is conducive to food safety and environmental protection, and gradually replaces traditional copper sulfate for feed additives , It has been promoted as an animal micronutrient supplement in domestic and foreign animal husbandry circles.
