Beschreibung
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.
Chemische Eigenschaften
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.
Verwenden
Ferric Chloride is a nutrient and dietary supplement that serves as a
source of iron.
Allgemeine Beschreibung
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.
Air & Water Reaktionen
Very hygroscopic. Slightly water soluble, where a 0.1M solution has a pH of 2.0.
Reaktivität anzeigen
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)].
Hazard
Toxic by ingestion, strong irritant to skin
and tissue.
Health Hazard
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.
Brandgefahr
Special Hazards of Combustion Products: Irritating hydrogen chloride fumes may form in fire.
Industrielle Verwendung
Ferric chloride (FeCl
3) 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.
Sicherheitsprofil
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.
mögliche Exposition
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.

material
läuterung methode
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.]
Inkompatibilitäten
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.
Waste disposal
Neutralize with lime or soda
ash and bury in an approved landfill.
