ECHEMI Editorial Reference

Boron trifluoride, boron trichloride, boron tribromide and boron triiodide are four kinds of common boron halides, the last three kinds of halogenated boron can be made in the presence of carbonaceous reducing agent by the high-temperature oxidation reduction of halogens and diboron trioxide, the reaction equation is as follows: B2O3 + 3C + 3Cl2 = 2BCl3 + 3CO, boron trifluoride is obtained by interaction of hydrogen fluoride (fluorspar with concentrated sulfuric acid) and diboron trioxide.

Air and Water Reactions:

Fumes in air, evolving hydrobromic acid. Reacts vigorously with water or explosively [Mellor 5:124 1946-47]. Borob Tribromide reacts vigorously with water to generate gaseous HBr. Based on a scenario where the chemical is spilled into an excess of water (at least 5 fold excess of water), half of the maximum theoretical yield of Hydrogen Bromide gas will be created in 0.18 minutes.
