Beschreibung
Copper chloride is a brownish-yellow powder.Molecular weight =134.44. Boiling point =993℃ (decomposes below this point); Freezing/Melting point =498℃.Hazard Identification (based on NFPA-704 M RatingSystem): Health 2, Flammability 0, Reactivity 0. Soluble inwater.
Chemische Eigenschaften
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.
Chemische Eigenschaften
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.
Verwenden
Supplement (trace mineral).
Verwenden
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.
Verwenden
Noble-Metal Nanostructures with Controlled Morphologies
Definition
ChEBI: An inorganic chloride of copper in which the metal is in the +2 oxidation state.
Allgemeine Beschreibung
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.
Reaktivität anzeigen
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.
Brandgefahr
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.
Sicherheitsprofil
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-.
mögliche Exposition
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.
Erste Hilfe
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.
Lager
Color Code—White: Corrosive or Contact Hazard;Store separately in a corrosion-resistant location. Prior toworking with this chemical you should be trained on itsproper handling and storage. Store in tightly closed containers in a cool, well-ventilated area away from incompatiblematerials listed above, moisture, and heat.

läuterung methode
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.]
Inkompatibilitäten
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.
