Cuprous chloride Chemical Properties,Uses,Production

Chemical Properties

white or pale grey powder

Chemical Properties

Copper chloride is a brownish-yellow powder.


As catalyst for organic reactions; catalyst, decolorizer and desulfuring agent in petroleum industry; in denitration of cellulose; as condensing agent for soaps, fats and oils; in gas analysis to absorb carbon monoxide.


Shows unique character as an initiator of radical reactions such as the hydrostannation of α,β-unsaturated ketones.1


It is used for absorption of carbon monoxide in gas analysis.


Copper chloride is also known as cupric chloride, this substance was made by treating copper carbonate with hydrochloric acid. The greenish blue crystals are soluble in water, alcohol, and ether. This halide was added to printing-out and silver bromide emulsions for increased contrast.


ChEBI: An inorganic chloride of copper in which the metal is in the +1 oxidation state.

First aid

Move victim to fresh air. Call 911 or emergency medical service. Give artificial respiration if victim is not breathing. Do not use mouth-to-mouth method if victim ingested or inhaled the substance; give artificial respiration with the aid of a pocket mask equipped with a one-way valve or other proper respiratory medical device. Administer oxygen if breathing is difficult. Remove and isolate contaminated clothing and shoes. In case of contact with substance, immediately flush skin or eyes with running water for at least 20 minutes. For minor skin contact, avoid spreading material on unaffected skin. Keep victim warm and quiet. Effects of exposure (inhalation, ingestion, or skin contact) to substance may be delayed. Ensure that medical personnel are aware of the material(s) involved and take precautions to protect themselves. Medical observation is recommended for 24 to 48 hours after breathing overexposure, as pulmonary edema may be delayed. As first aid for pulmonary edema, a doctor or authorized paramedic may consider administering a drug or other inhalation therapy.


UN2802 Copper chloride, Hazard class: 8; Labels: 8-Corrosive material.

Purification Methods

Wash the solid with ethanol and diethyl ether, then dry it and store it in a vacuum desiccator [.sterl.f Acta Chem Scand 4 375 1950]. Alternatively, to an aqueous solution of CuCl2.2H2O is added, with stirring, an aqueous solution of anhydrous sodium sulfite. The colourless product is dried at 80o for 30minutes and stored under N2. Cu2Cl2 can be purified by zone-refining [Hall et al. J Chem Soc, Faraday Trans 1 79 343 1983]. [Glemser & Sauer in Handbook of Preparative Inorganic Chemistry (Ed. Brauer) Academic Press Vol II p 1005 1965.]


Contact with strong acids forms monovalent copper salts and toxic hydrogen chloride gas. Forms shock-sensitive and explosive compounds with potassium, sodium, sodium hypobromite, nitromethane, acetylene. Keep away from moisture and alkali metals. Attacks metals in the presence of moisture. Reacts with moist air to form cupric chloride dihydrate. May attack some metals, paints, and coatings. May be able to ignite combustible materials.
