Antimony (III ) fluoride is a fluoride of antimony. It is at room temperature as colorless to slightly greyish crystals with a pungent odor before.

Production and representation

Antimony trifluoride can be prepared by reaction of anhydrous hydrogen fluoride with antimony trioxide. This results in antimony (III ) fluoride and water.

Properties

Physical Properties

Antimony (III ) fluoride autodissoziert to anti Mondi fluoride and Antimontetrafluridionen.

This directs molten antimony and electricity. Antimodifluoridionen be stabilized by the antimony (III ) fluoride molecules.

Chemical Properties

Antimony (III ) fluoride is a strong Lewis acid, but a relatively weak Lewis base. With Donorfluoriden it is fluoro.

Use

Antimony (III ) fluoride is considered moderately active fluorinating agent, preferably, used for low-melting fluorides. These can then be distilled off from the excess of antimony (III ) fluoride. It is also used as a mordant for dyeing, and is used in the manufacture of ceramics.

Safety

Antimony (III ) fluoride is toxic to humans. Inhalation of antimony (III ) fluoride may cause chemical pneumonia and pulmonary edema. Direct contact may cause severe damage to the skin, the tissue of the mucous membranes and the respiratory tract and eyes.
