化学的特性
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.
使用
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.
定義
ChEBI: An inorganic chloride of copper in which the metal is in the +2 oxidation state.
安全性
銅塩化物は適切に取り扱う必要がある化学物質です吸入や摂取は健康に害を及ぼす可能性があり皮膚や目に対する刺激も報告されていますしたがってこの物質を使用する際には適切な保護具を着用し良好な換気が確保された環境で作業を行うことが重要です
一般的な説明
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.
反応プロフィール
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.
健康ハザード
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.
火災危険
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.
化学性质
銅塩化物は水に対する溶解度が高いことが特徴でありこの性質が多くの化学反応での利用を可能にしていますまた銅塩化物は酸化剤としても働き有機合成反応や塩素の生成に利用されますさらにこの物質は熱を加えると脱水しやすく色の変化を伴って無水物へと変化します

輸送方法
UN2802 Copper chloride, Hazard class: 8; Labels: 8-Corrosive material.
純化方法
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.]
不和合性
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.
