Boron Trifluoride
Boron Trifluoride
Formula: BF3
CAS No: 7637-07-02
Boron Trifluoride (BF3) is a colorless, toxic, and corrosive gas with a pungent odor. It is a strong Lewis acid, making it an important catalyst and reagent in a wide range of industrial processes. In the presence of moisture, BF3 forms hydrofluoric acid, which can corrode certain metals, so careful selection of equipment materials is essential.
Applications include:
-
Catalyst and reagent in organic synthesis for alkylation, polymerization, esterification, and isomerization reactions in chemical and pharmaceutical production.
-
P-type dopant gas in ion implantation for integrated circuit manufacturing, introducing boron atoms into epitaxially grown silicon layers to adjust electrical properties.
-
Radiation detection in neutron detectors, ionization chambers, and atmospheric radiation monitoring.
-
Fumigation agent in certain pest control applications.
-
Protection of molten magnesium and its alloys from oxidation during melting and casting.
-
Precursor for BF3 complexes used as catalysts in polymer and resin manufacturing.
Material compatibility:
Equipment used to handle BF3 is typically constructed from stainless steel, Monel®, or Hastelloy®. In the presence of moisture, BF3 forms hydrofluoric acid, which can corrode carbon steel and stainless steel. It also reacts with polyamides.
