• Chemische Eigenschaften

  Chromic chloride is a highly corrosive, Blue or greenish to black crystalline solid.

• Verwenden

  Supplement(trace mineral).
  Chromium(III) chloride and chromium(III) sulfate have been used as dietary supplements (approved for themanufacture of foods for particular nutritional uses and in food supplements in the European Union), whereas the organic chromium(III) complexes chromium picolinate and nicotinate are not approved in the European Union but find widespread uses (e.g. in the USA) inmultivitamin, multimineral products (Riihimaki & Luotamo, 2006).They are also marketed for weight loss purposes and athletic supplements.

• Verwenden

  Chromium chloride and chromium sulfate have been used as dietary supplements. Chromium(III) chloride and chromium(III) sulfate can be used in the manufacture of food for particular nutritional uses and in food supplements. It is found in miscellaneous applications, such as catalysts, hardeners, mordents, crosslinking and binding agents. It is used to make very pure chromium and other chromium compounds, as a mordant in dyeing cotton, and in chromizing metals. It is too used for trivalent electroplating .

• Air & Water Reaktionen

  The rate of solution for water is extremely slow, pH of 0.2 M. aqueous solution is 2.4.

• Reaktivität anzeigen

  When heated to decomposition, CHROMIUM (III) CHLORIDE emits toxic fumes of chlorine containing compounds. Violent reaction with lithium, nitrogen. Incompatible with strong oxidizers. [EPA, 1998].

• Hazard

  A poison.

• Health Hazard

  CHROMIUM (III) CHLORIDE displays high dermal toxicity, and moderate oral toxicity.

• Flammability and Explosibility

  Non flammable

• Sicherheitsprofil

  Poison by skin contact, inhalation, and intraperitoneal routes. Experimental teratogenic and reproductive effects. Human mutation data reported. Questionable carcinogen. Reacts violently with lithium under nitrogen atmosphere. When heated to decomposition it emits toxic fumes of Cl-.

• mögliche Exposition

  Chromic chloride is used for production of solutions of basic chlorides and as a catalyst for polymerization of olefins and other organic reactions; in chromizing; in the manufacture of chromium metal and compounds; as a textile mordant; in tanning; in corrosion inhibitors; and as a waterproofing agent. A nutritional supplement.

• 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. Seek medical attention immediately. If this chemical contacts theskin, remove contaminated clothing and wash immediatelywith soap and water. Seek medical attention immediately. Ifthis chemical has been inhaled, remove from exposure,begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR ifheart action has stopped. Transfer promptly to a medicalfacility. When this chemical has been swallowed, get medical attention. Give large quantities of water and inducevomiting. Do not make an unconscious person vomit.

• Lager

  : Color Code—White: Corrosive or Contact Hazard;Store separately in a corrosion-resistant location. ColorCode—Green: General storage may be used. Prior to working with this chemical you should be trained on its properhandling and storage. Store in tightly closed containers in acool, well-ventilated area away from oxidizing agents andwater

• läuterung methode

  Sublime the chloride in a stream of dry HCl. Alternatively, the impure chromic chloride (100g) is added to 1L of 10% aqueous K2Cr2O7 and several millilitres of conc HCl, and the mixture is brought to a gentle boil with constant stirring for 10minutes. (This removed a reducing impurity.) The solid is separated and washed by boiling with successive 1L lots of distilled water until the wash water no longer gives a test for chloride ion, then dry it at 110o [Poulsen & Garner J Am Chem Soc 81 2615 1959, Hein & Herzog in Handbook of Preparative Inorganic Chemistry (Ed. Brauer) Academic Press Vol II p 1338 1965].

• Inkompatibilitäten

  Reacts with water and strong oxidizers. Contact with strong acids or acid fumes may produce highly toxic chloride fumes. May attack certain steels, causing pitting attack and stress corrosion

• Waste disposal

  Precipitate as chromium hydroxide. Dewater the sludge and dispose of the compacted sludge in single-purpose dumps
