Boron tribromide Usage And Synthesis
Chemical Properties clear to amber liquid with a pungent odour
Usage Boron Tribromide is used as a reagent in the synthesis of 8-hydroxyquinolato compounds used as electron transport materials in EL devices. It is also used in the demethylation of aryl methyl ethers by boron tribromide.
General Description A colorless, fuming liquid with a pungent odor. Boiling point 194°F. Freezing point -51°F. Very toxic by inhalation. Corrosive to metals and tissue.
Reactivity Profile Boron tribromide strongly attacks wood and rubber with generation of flammable hydrogen gas. Reacts exothermically and violently with water. Mixing tungsten trioxide and Boron tribromide caused an explosion when the reaction was not cooled in an ice bath.
Health Hazard Inhalation causes severe irritation of mucous membranes. Ingestion causes burns of mouth and stomach. Contact with eyes or skin causes severe burns.
Fire Hazard Special Hazards of Combustion Products: Toxic fumes of the chemical or hydrogen bromide may form in fires.
