• 説明

  Ferric chloride (iron(IH)chloride, FeCl3, CAS No. 7705-08-0) may be prepared from iron and chlorine or from ferric oxide and hydrogen chloride. The pure material occurs as hydroscopic, hexagonal, dark crystals. Ferric chloride hexahydrate (iron(III)chloride hexahydrate, FeCl3*6H2O, CAS No. 10025-77-1) is readily formed when ferric chloride is exposed to moisture.

• 化学的特性

  Ferric chloride,FeCl3, is a brown crystalline solid and is soluble in water,alcohol,and glycerol. It is also known as anhydrous ferric chloride,ferric trichloride, Flores martis,and iron chloride. Ferric chloride is used as a coagulant for sewage and industrial wastes, as an oxidizing and chlorinating agent,as a disinfectant, in copper etching, and as amordant. In addition, this compound is employed in the ferric chloride test,which is used to assess the relative corrosion resistance of stainless and nickel-base alloys. The ferric chloride test has been shown to be an appropriate measure of the suitability of such alloys for service in paper mill bleach plants and seawater.

• 使用

  Ferric Chloride is a nutrient and dietary supplement that serves as a source of iron.

• 一般的な説明

  Ferric chloride is an orange to brown-black solid. Ferric chloride is slightly soluble in water. Ferric chloride is noncombustible. When wet Ferric chloride is corrosive to aluminum and most metals. Pick up and remove spilled solid before adding water. Ferric chloride is used to treat sewage, industrial waste, to purify water, as an etching agent for engraving circuit boards, and in the manufacture of other chemicals.

• 空気と水の反応

  Very hygroscopic. Slightly water soluble, where a 0.1M solution has a pH of 2.0.

• 反応プロフィール

  Alkali metal hydroxides, acids, anhydrous chlorides of iron, tin, and aluminum, pure oxides of iron and aluminum, and metallic potassium are some of the catalysts that may cause ethylene oxide to rearrange and polymerize, liberating heat, [J. Soc. Chem. Ind. 68:179(1949)]. Explosions occur , although infrequently, from the combination of ethylene oxide and alcohols or mercaptans, [Chem. Eng. News 20:1318(1942)]. Allyl chloride may polymerize violently under conditions involving an acid catalyst, such as sulfuric acid, Ferric chloride, aluminum chloride, Lewis acids, and Ziegler type catalysts (initiators), [Ventrone (1971)].

• 危険性

  Toxic by ingestion, strong irritant to skin and tissue.

• 健康ハザード

  Inhalation of dust may irritate nose and throat. Ingestion causes irritation of mouth and stomach. Dust irritates eyes. Prolonged contact with skin causes irritation and burns.

• 火災危険

  Special Hazards of Combustion Products: Irritating hydrogen chloride fumes may form in fire.

• 化学性质

  黒褐色，融点306℃，300℃以上で昇華性

• 工業用途

  Ferric chloride (FeCl₃) is obtained by an iron chlorination method at a temperature of 600–700 °C. Very limited data are available on the use of ferric chloride in the mineral processing industry. Ferric chloride has a depressing effect on barite and can be used in barite–celestite separation. It was also evaluated as a depressant during niobium– zirconium separation. In general, ferric and ferrous compounds are not selective depressants and in many cases are detrimental for flotation of oxidic and industrial minerals as in the case of anionic flotation, fatty acid, iron complexes or oleate iron complexes.

• 安全性プロファイル

  Poison by ingestion and intravenous routes. Experimental reproductive effects. Corrosive. Probably an eye, skin, and mucous membrane irritant. Mutation data reported. Reacts with water to produce toxic and corrosive fumes. Catalyzes potentially explosive polymerization of ethylene oxide, chlorine + monomers (e.g., styrene). Forms shock sensitive explosive mixtures with some metals (e.g., potassium, sodium). Violent reaction with all$ chloride. When heated to decomposition it emits highly toxic fumes of HCl.

• 職業ばく露

  Iron chloride is used to treat sewage and industrial waste. It is also used as an etchant for photo engraving and rotogravure; in textiles; photography; as a disinfectant; as a feed additive.

• エッチング

  金属表面に腐食液をつけて部分的に溶かし，模様を作りだすことをエッチングという．銅版などのエッチングには，塩化第二鉄 FeCl3 の水溶液が使われる．本実験では，レジスト膜に覆われていない部分のニッケルめっきを溶かすが，その反応式は次のように書ける．
  Ni + 2FeCl3 → NiCl2 + 2FeCl2
  つまり，Fe3+が Fe2+に還元され，その一方で金属 Ni が Ni2+に酸化され，水溶液中に溶け出す．

• 合成方法

  UN1773 Ferric chloride, anhydrous, Hazard class: 8; Labels: 8-Corrosive material. UN2582 Ferric chlo ride, solution, Hazard class: 8; Labels: 8-Corrosive material

• 純化方法

  Sublime it at 200o in an atmosphere of chlorine. It is an “iron-black” coloured powder with green irridescence. Store it in a weighing bottle inside a desiccator as it absorbs moisture from air to form the yellow hexahydrate (see next entry). [Tarr Inorg Synth III 191 1950, Pray Inorg Synth V 153 1957, Epperson Inorg Synth VII 163 1963.]

• 不和合性

  Aqueous solutions are a strong acid. Violent reaction with bases, allyl chloride; sulfuric acid; water. Shock- and friction-sensitive explosive material forms with potassium, sodium and other active metals. Attacks metals when wet.

• 廃棄物の処理

  Neutralize with lime or soda ash and bury in an approved landfill.
