염화 제II구리 C화학적 특성, 용도, 생산

화학적 성질

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.

화학적 성질

Copper chloride is a brownish-yellow powder.


Supplement (trace mineral).


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

일반 설명

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.

반응 프로필

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.


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.


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.

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-.

운송 방법

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

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.]

비 호환성

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.
