Physical and chemical properties

Copper chloride trihydroxide is a green or dark green crystalline powder that is insoluble in water but soluble in dilute acids and ammonia water. Reacting with alkali to form a blue flocculent precipitate, which is copper hydroxide and decomposes in boiling water to form black copper oxide.

Very stable in the air. The water absorption is very low, and it is not easy to clump. The surface of basic copper chloride solid particles is neutral, and it is not easy to react with other substances.

Purpose

Used as pesticide intermediates, pharmaceutical intermediates, wood preservatives, feed additives, etc.

Basic copper chloride is a trace mineral used as a copper source in feed, with a copper content of up to 58%. This alkaline salt is insoluble in water but easily and quickly dissolves in the intestines of animals. Compared with other copper sources, basic copper chloride has a high utilization rate and can be quickly dissolved in the digestive tract. Stable and low hygroscopicity, does not accelerate the oxidation of vitamins and antibiotics. The biological efficacy and safety of basic copper chloride are higher than those of copper sulfate. The usage of copper is reduced by 25% to 30% compared to copper sulfate, which can completely replace copper sulfate. Not only does it reduce feed costs, but it can also greatly reduce the pollution of copper excretion to the environment. Basic copper chloride is a good source of animal copper.
