What Is Copper Chloride Dihydrate?

Copper chloride dihydrate (CuCl₂·2H₂O) is a blue-green crystalline salt produced by dissolving copper metal or copper oxide in hydrochloric acid. It is one of the most versatile copper salts in industrial chemistry, functioning as a catalyst, an oxidant, a wood preservative, and a source of copper ions in electroplating and chemical processing applications.

Galvanoplastie et traitement de surface

In the electronics industry, copper chloride is used in printed circuit board (PCB) etching baths to remove unwanted copper from circuit patterns. It also serves as a source of copper ions in various electroplating processes and in cupric chloride regeneration systems used to recycle spent etchant, reducing waste and chemical consumption in PCB manufacturing.

Catalysis & Chemical Synthesis

Copper chloride dihydrate is an important catalyst in the Wacker process for the oxidation of ethylene to acetaldehyde. It catalyses chlorination reactions and serves as a Lewis acid catalyst in various organic transformations. In chemical synthesis it is used to prepare organocopper reagents and as a co-catalyst in oxidative coupling reactions of terminal alkynes.

Wood Treatment & Agricultural Uses

Copper chloride is used as a wood preservative in formulations designed to protect timber against fungal decay and insect attack. In agriculture it contributes to copper-based fungicide preparations. It is also used in the dyeing of textiles as a mordant and in the production of other copper chemicals including copper oxide and copper sulfate.
