DOT-Kennzeichnung	Corrosive Poison
Brandgefahren	Reacts violently with water, to form poisonous hydrogen fluoride fumes. If confined and wet can cause explosion. May cause fire in contact with combustible material. Hazardous polymerization may not occur. (EPA, 1998)· Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes.Not combustible but enhances combustion of other substances. Gives off irritating or toxic fumes (or gases) in a fire.
Brandpotenzial	Not combustible, but if involved in a fire decomposes to produce fumes of antimony and hydrogen fluoride. Contact with combustible materials may increase the fire hazard.
Gesundheitsgefahren	The compound is irritating to eyes, skin, and lungs. Contact with eyes or skin causes severe burns. The compound is extremely toxic with a probable oral lethal dose of 5-50 mg/kg or between 7 drops and one teaspoonful for a 150 pound person (antimony salts). (EPA, 1998)· TOXIC and/or CORROSIVEinhalation, ingestion or contact (skin, eyes) with vapors, dusts or substance may cause severe injury, burns or death.

Anwendungen & Verwendung

Verwenden

HF/SbF5 is an excellent medium for the preparation of alkylidene oxonium salts.1

Herstellung & Synthese

synthetische

Antimony pentafluoride is prepared by the reaction of antimony pentachloride with anhydrous hydrogen fluoride:SbCl5 +5 HF → SbF5 +5 HClIt may also be prepared from antimony trifluoride and fluorine, or by treating antimony pentaoxide with aqueous hydrofluoric acid and evaporing water.
