Boron tribromide, BBr3, is a colorless, fuming liquid compound containing boron and bromine. English name Boron tribromide Vapor pressure 5.33kPa(14°C) Melting point, boiling point -45°C,91.7°C The Instructions of Boron Tribromide Boron tribromide, BBr3, is a colorless, fuming liquid compound containing boron and bromine. It is usually made by heating boron trioxide with carbon in the presence of bromine: this generates free boron which reacts vigorously with the bromine. It is very volatile and fumes in air because it reacts vigorously with water to form boric acid and hydrogen bromide. Uses,Boron tribromide is used as catalyst, intermediate and brominating agent in organic synthesis and is the raw material of making high-purity boron powder and other organoboron compound. It is also used as the dopant source of the semiconductor silicon and is used to make the high-purity boron and the organoboron compound.
