Project at a Glance Contents on the CD ROM
  • Boron trifluoride is the chemical compound with the formula BF3. This pungent colourless toxic gas forms white fumes in moist air. It is a useful Lewis acid and a versatile building block for other boron compounds.
  • Boron has three valence electrons. Fluorine has seven valence electrons. There are a total of 3e- x 1 boron + 7e- x 3 fluorines = 24 valence electrons to be placed in the Lewis structure for boron trifluoride.
  • BF3 is manufactured by the reaction of boron oxides with hydrogen fluoride.
  • Boron trifluoride is corrosive. Suitable metals for equipment handling boron trifluoride include stainless steel, monel, and hastelloy. In presence of moisture it corrodes steel, including stainless steel. It reacts with polyamides.
    Polytetrafluoroethylene, polychlorotrifluoroethylene, polyvinylidene fluoride, and polypropylene show satisfactory  resistance. The grease used in the equipment should be fluorocarbon based, as boron trifluoride reacts with the  hydrocarbon-based ones.
  • Boron trifluoride reacts with water to give boric acid and fluoroboric acid. The reaction commences with the formation of the aquo adduct, H2O-BF3, which then loses HF that gives fluoboric acid with boron trifluoride.
  • Boron trifluoride is most importantly used as a reagent in organic chemistry, typically as a Lewis acid.
  • Boron trifluoride initiates polymerisation reactions of unsaturated compounds such as polyethers as a catalyst in some isomerization, alkylation, esterification, condensation, Mukaiyama aldol addition, and other reactions.
  • Boron trifluoride applied as dopant in ion implantation.
  • Boron trifluoride used in sensitive neutron detectors in ionization chambers and devices to monitor radiation levels in the Earth's atmosphere.
  • Boron trifluoride used in fumigation.
  • Boron trifluoride used as a flux for soldering magnesium.
  • Boron trifluoride used to prepare diborane.
  • Boron Trifluoride is a non-flammable compressed gas, packaged and shipped in
    cylinders under high pressure. It is often advantageous to use BF3 in a complexed form so that BF3 can be released under preferred conditions.BF3 complexes are typically liquids or solids and therefore may be more easily managed than the high pressure gas.
