Abstract

The invention discloses a preparation method of copper chloride hydroxide. The method comprises the following steps: adding copper hydroxide slurry in copper chloride solution according to a ratio of 2.5-3.5:1, reacting under the condition that the temperature is 80-160 DEG C, the pH value is 4-9 and the pressure is 0-600kPa, obtaining the reaction product after the reaction; and rinsing, centrifuging and drying the reaction product to obtain copper chloride hydroxide. The method of the invention has simple and safe operation, less waste discharge, lower production cost, more complete resource utilization and less environmental pollution.

Description

technical field [0001] The invention relates to a preparation method of a copper compound, in particular to a preparation method of a copper halide. Background technique [0002] Copper plays an important role in maintaining the normal metabolism and immunity of the body. Feeding experiments show that adding high copper in the feed can improve the daily gain, feed intake and feed efficiency of animals, and has the effect of promoting growth. At present, copper sulfate is mainly used as a source of copper in feed, and its biggest advantage is its low price. However, a large amount of copper sulfate will cause other serious problems. On the one hand, it has an antagonistic effect on trace elements such as Fe and Zn, and on the other hand On the one hand, due to the high solubility of copper sulfate, it aggravates the pollution to the environment after being discharged in large quantities. More seriously, Cu in the feed 2+ It is easily reduced, and this reduction reaction wil...
