Tribromofluoromethane is a chemical compound of bromine from the group of halogenated hydrocarbons .
Extraction and presentation
Tribromofluoromethane can be obtained by reacting tetrabromomethane with bromine trifluoride , antimony trifluoride (also together with bromine ) or silver (I) fluoride .
properties
Tribromofluoromethane is a clear, colorless liquid that is insoluble in water. In the solid state, the compound has an orthorhombic crystal structure with the space group Pnma (space group no. 62) .
use
Tribromofluoromethane is used in the synthesis of organic compounds such as dibromofluoromethyllithium , which when reacted with an aldehyde or ketone gives fluorinated alcohols. It was also used for extinguishing fires.
