Formula
F5-Sb
Major Category
Toxic Gases & Vapors
Antimony pentafluoride formula graphical representation
Synonyms
Antimony (V) fluoride; Antimony fluoride; Pentafluoroantimony; [ChemIDplus]
Category
Other Toxic Gases & Vapors
Description
Viscous liquid with a sharp odor; [HSDB]
Sources/Uses
Used as a catalyst and fluorinating agent; [HSDB]
Comments
Hydrofluoric acid formed when F5-Sb reacts with water; Corrosive to eyes, skin, and respiratory tract; Can cause acute pulmonary edema after heavy inhalation exposure; In chronic inhalation studies of animals, pneumonitis as well as liver and cardiac damage are observed. Repeated exposures to fluoride compounds can result in fluorosis. [HSDB] Recent experiments show that "there is essentially very little HF formation; the substance was quite unreactive in water."
