Bromopentafluoride is an interhalogen compound consisting of the elements bromine and fluorine .
Extraction and presentation
Bromine pentafluoride can be obtained by reacting bromine with fluorine.
properties
Bromopentafluoride is a colorless, pungent smelling liquid that smokes heavily in the air, decomposes in water and attacks almost all materials. With organic compounds, the reaction is sometimes very violent and under certain circumstances explosive. The substance itself is non-flammable, but reacts so strongly with flammable substances that no ignition source is required for a fire, and existing fires are strongly encouraged. Dry glass is slowly attacked at normal temperature, quartz glass is practically not attacked at all.
use
Bromopentafluoride is used for fluorination in inorganic chemistry.
safety instructions
Bromine pentafluoride is poisonous, oxidizes and causes chemical burns. It should be stored in a cool and dry place.
