• Beschreibung

  admium bromide is a white to yellowishcrystalline powder. Molecular weight=272.22; BoilingCadmium bromide 505point=863℃; Freezing/Melting point=567℃. HazardIdentification (based on NFPA-704 M Rating System):Health 3, Flammability 0, Reactivity 0. Soluble in water.

• Chemische Eigenschaften

  Cadmium bromide is a white to yellowish crystalline powder.

• Chemische Eigenschaften

  White to yellowish crysatlline powder

• Physikalische Eigenschaften

  White to yellowish powder or flakes; hexagonal crystal system; hygroscopic; density 5.192g/cm³; melts at 568°C; vaporizes at 844°C; soluble in water, alcohol, ether, acetone, and liquid ammonia.

• Verwenden

  Made by heating cadmium to redness in bromine vapor. The yellowish crystalline powder is soluble in water and alcohol and is slightly soluble in ether. The crystals are deliquescent and must be kept in a well-stoppered bottle. Like its iodide counterpart, cadmium bromide was used in collodion in conjunction with an iodide of either ammonium or potassium.

• Verwenden

  This compound is used in photography, engraving, and lithography. The other halogen elements also combine with cadmium in a similar ionic reaction as with bromine.

• Verwenden

  Process engraving, lithography and photography

• Verwenden

  In photography, process engraving, and lithography.

• synthetische

  Cadmium bromide is prepared by heating cadmium with bromine vapor. Also the compound can be prepared by the treatment of dry cadmium acetate with glacial acetic acid and acetyl bromide. Alternatively, it may be obtained by dissolving cadmium or cadmium oxide in hydrobromic acid and evaporating the solution to dryness under helium in an inert atmosphere.

• Allgemeine Beschreibung

  Odorless white solid. Mixes with water.

• Air & Water Reaktionen

  Water soluble.

• Reaktivität anzeigen

  CADMIUM BROMIDE 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.

• Health Hazard

  Inhalation causes coughing, sneezing, symptoms of lung damage. Ingestion produces severe toxic symptoms; both kidney and liver injuries may occur. Contact with eyes causes irritation.

• Brandgefahr

  Special Hazards of Combustion Products: Toxic cadmium oxide fumes may form in fires.

• Sicherheitsprofil

  Confirmed human carcinogen. When heated to decomposition it emits toxic fumes of Cd and Br-.

• mögliche Exposition

  Cadmium bromide is used in photography, engraving, and lithography

• 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. Seekmedical 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,506 Cadmium bromideincluding resuscitation mask) if breathing has stopped andCPR if heart action has stopped. Transfer promptly to amedical facility. When this chemical has been swallowed,get medical attention. Give large quantities of water andinduce vomiting. Do not make an unconscious personvomit. Medical observation is recommended for 24-48 hafter breathing overexposure, as pulmonary edema may bedelayed. As first aid for pulmonary edema, a doctor orauthorized paramedic may consider administering a corticosteroid spray.Note to physician: For severe poisoning do not use BAL[British Anti-Lewisite, dimercaprol, dithiopropanol(C3H8OS2)] as it is contraindicated or ineffective in poisoningfrom cadmium.

• Lager

  Color Code—Blue: Health Hazard: Store in asecure poison location. Prior to working with cadmiumbromide you should be trained on its proper handling andstorage. Cadmium bromide must be stored to avoid contactwith Potassium, since violent reactions occur. A regulated,marked area should be established where this chemical ishandled, used, or stored in compliance with OSHAStandard 1910.1045.

• läuterung methode

  Crystallise it from water (0.6mL/g) between 100o and 0o, and dry it at 110o. It forms the monohydrate below 36o and the tetrahydrate above 36o. [Wagenknecht & Juza in Handbook of Preparative Inorganic Chemistry (Ed. Brauer) Academic Press Vol II p 1096 1965.]
