Copper(II) chloride dihydrate Chemical Properties,Usage,Production

Description Copper (II) chloride dihydrate is used in the preparation of copper oxychloride and as a catalyst in many organic chlorination reactions such as vinyl chloride and 1,2-dichloroethane. Copper chloride dihydrate may be also used as catalyst to cleave tetrahydropyranyl (THP) ethers and t-butyldimethylsilyl (TBDMS) ethers and to chemoselectively hydrolyze semicarbazones to carbonyl compounds. Solution of copper (II) chloride is used for plating on aluminum and for tinting germanium and tin.
Uses Copper(II) chloride is used as a mordant in dyeing and printing of fabrics; as an ingredient of isomerization and cracking catalysts; and as a desulfurizing and deodorizing agent in petroleum industry.
Other important applications are in copper plating of aluminum; preparation of copper standard solutions; test for molybdenum; in tinting-baths for iron and tin; in pigments for ceramics and glasses; as a fixer and desensitizer reagent in photography; in mercury extraction from ores; in laundry-marking and invisible inks; and in manufacture of several copper salts.
Preparation Copper(II) chloride may be synthesized by heating elemental copper with chlorine:
Cu + Cl2 CuCl2
Alternatively, it may be prepared by treating copper carbonate with hydrochloric acid followed by crystallization:
CuCO3 + 2HCl → CuCl2 + CO2 + H2O
In the above preparation, the hydrate of the salt crystallizes, precipitates, and may be dehydrated by heating under vacuum.

Chemical Properties Moist blue crystals.
Uses Copper(II) chloride (CuCl2) or cupric chloride, is a brownish-yellow hygroscopic powder, or it may be formed as green deliquescent crystals. It is used in the dyeing and printing of textiles, as a disinfectant, as red pigment in the glass and ceramic industries, and for green-colored pyrotechnics, wood preservative, fungicide, deodorizer, water purification, feed additive, and electroplating baths.
Uses Supplement (trace mineral).
Uses Copper(II) chloride dihydrate has been used as a positive control in dispersion of zebrafish embryo. It has also been used for the preparation of trace metals mixture.
Definition ChEBI: Copper(II) chloride dihydrate is a hydrate that is the dihydrate form of copper(II) chloride. It occurs naturally as the mineral eriochalcite. It has a role as an EC 5.3.3.5 (cholestenol Delta-isomerase) inhibitor. It is a hydrate and a halide mineral. It contains a copper(II) chloride.
