Copper(II) chloride

Absorption

Mean copper absorption of 57 percent (range 40 to 70 per cent) following oral administration of 0.4 - 4.5 mg copper (as copper acetate) to four volunteers. An early human study suggested a maximum blood copper concentration was reached some two hours after oral copper chloride administration (1.5 - 12 mg copper)

Toxicity

LD50 not available Copper toxicity can produce prostration, behavior change, diarrhea, progressive marasmus, hypotonia, photophobia and peripheral edema. Such symptoms have been reported with a serum copper level of 286 mcg/dl. Copper toxicity can also result in hemolysis and liver toxicity, including hepatic necrosis which may be fatal. D-penicillamine has been reported effective as an antidote.

Chemical properties

Cupric chloride, CuCI2, also known as copper chloride, is a yellowish- brown solid that is soluble in water and alcohol. The dihydrate of cupric chloride, CUCI2·H20, is a green crystalline solid that is soluble in water. Cupric chloride is used in the textile industry as a mordant in the dyeing and printing of fabrics. Itis also used in refining gold,silver,and copper.

Chemical properties

Cupric Chloride, brown-yellow powder, quite soluble in cold H2O or alcohol, very soluble in hot H2O. Catalyst for several organic syntheses, including production of vinyl chloride monomer.

The Uses of Copper(II) chloride

Isomerization and cracking catalyst, mordant in dyeing and printing fabrics, in electroplating baths for plating Cu on Al, in photography as a fixer, as a pigment for glass and ceramic.Copper(II) chloride is used as a co-catalyst with palladium(II) chloride used in the Wacker process to prepare ethanol from ethane. It acts as an effective catalyst for the tetrahydropyranylation of alcohols. It is involved in the production of vinyl chloride and dichloroethane as well as in the chlorination of aromatic hydrocarbons. It acts as deodorizing and desulfurizing agent in the petroleum industry, a mordant in textiles industry and in electrotyping baths for plating copper.

The Uses of Copper(II) chloride

Supplement (trace mineral).

The Uses of Copper(II) chloride

Noble-Metal Nanostructures with Controlled Morphologies

Indications

For use as a supplement to intravenous solutions given for total parenteral nutrition (TPN).

Background

Cupric chloride, for injection, is a sterile, nonpyrogenic solution intended for use as an additive to solutions for Total Parenteral Nutrition (TPN).

What are the applications of Application

Copper(II) chloride is a compound used with palladium in catalytic synthesis of 3-haloindoles

Definition

ChEBI: An inorganic chloride of copper in which the metal is in the +2 oxidation state.

General Description

Cupric chloride and ammonia contains various concentrations of cupric chloride in ammonium hydroxide. This forms a copper ammonia complex. Cupric chloride is corrosive to skin, eyes, mucous membranes and metal. Cupric chloride is used to etch copper from printed circuit boards.

Reactivity Profile

CUPRIC CHLORIDE has weak oxidizing or reducing powers. Redox reactions can however still occur. The majority of compounds in this class are slightly soluble or insoluble in water. If soluble in water, then the solutions are usually neither strongly acidic nor strongly basic. These compounds are not water-reactive.

Health Hazard

TOXIC; inhalation, ingestion or skin contact with material may cause severe injury or death. Contact with molten substance may cause severe burns to skin and eyes. Avoid any skin contact. Effects of contact or inhalation may be delayed. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution.

Fire Hazard

Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. Some are oxidizers and may ignite combustibles (wood, paper, oil, clothing, etc.). Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated.

Pharmacokinetics

Copper is an essential nutrient which serves as a co factor for serum ceruloplasmin, an oxidase necessary for proper formation of the iron carrier protein, transferrin. Copper also helps maintain normal rates of red and white blood cell formation. Providing copper during Total Parenteral Nutrition helps prevent development of the following deficiency symptoms: Leukopenia, neutropenia, anemia, depressed ceruloplasmin levels, impaired transferrin formation, secondary iron deficiency and osteoporosis.

Safety Profile

Poison by intravenous and intraperitoneal routes. Experimental reproductive effects. Mutation data reported. See also COPPER COMPOUNDS and CHLORIDES. Can react violently with K and Na. When heated to decomposition it emits toxic fumes of Cl-.

Potential Exposure

Copper chloride is used in petroleum,textiles, metallurgy, photography, agricultural products,feed additives, and wood preservation. It is also used inlight-sensitive paper manufacturing, glass pigments, ceramics, and in making cyclonitrile.

First aid

If this chemical gets into the eyes, remove anycontact lenses at once and irrigate immediately for at least15 min, occasionally lifting upper and lower lids. Seekmedical attention immediately. If this chemical contactsthe skin, remove contaminated clothing and wash immediately with soap and water. Seek medical attention immediately. If this chemical has been inhaled, remove fromexposure, begin rescue breathing (using universal precautions, including resuscitation mask) if breathing hasstopped and CPR if heart action has stopped. Transferpromptly to a medical facility. When this chemicalhas been swallowed, get medical attention. If victim isconscious, administer water or milk. Do not inducevomiting.

Purification Methods

Crystallise the chloride from hot dilute aqueous HCl (0.6mL/g) by cooling in a CaCl2-ice bath. It is dehydrated by heating on a steambath under vacuum. It is deliquescent in moist air but efflorescent in dry air. The dihydrate is emerald green but blue when free from solvent. Concentrated solutions are yellow-green in colour but are blue when free from solvent. Concentrated solutions are yellow-green and become yellow on adding conc HCl. A very dilute solution is pure blue due to Cu(H2O)42+ [Donan & Bassett J Chem Soc 81 939 1902.]. CuCl2 is very deliquescent and is soluble in MeOH or EtOH to give green crystals of Cu(ROH)2Cl2. [Glemser & Sauer in Handbook of Preparative Inorganic Chemistry (Ed. Brauer) Academic Press Vol II p 1008 1965.]

Incompatibilities

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.
