Products Description of Boron Tribromide CAS#10294-33-4
Boron tribromide is an inorganic compound that exists as a colorless liquid at room temperature. When exposed to moisture in the air, it reacts to produce smoke, boric acid, and hydrogen bromide.
Boron tribromide can be synthesized by heating boron trioxide, carbon, and bromine. During this process, boron is first generated through the reaction and then reacts directly with bromine to form boron tribromide.
