Boron Trifluoride (BF3)

The English name of boron trifluoride is Boron trifluoride. Also known as boron fluoride. CAS number 7637-07-2, molecular weight 67.81. It is an inorganic compound, colorless gas, suffocation, and hydrolyzes immediately when exposed to moisture in the air. When decomposed, highly toxic fluoride smoke is generated. Fluoroborate ions are non-coordinating anions, and liquid boron trifluoride etherate is often used as the source of boron trifluoride in the laboratory. It can be prepared by reacting boron trioxide or borate with hydrogen fluoride. High-energy fuel used to make rockets. It is mainly used as a catalyst for organic reactions, such as esterification, alkylation, polymerization, isomerization, sulfonation, nitration, etc. Antioxidant when casting magnesium and alloys. It is the main raw material for preparing boron halide, elemental boron, borane, sodium borohydride, etc. In many organic reactions and petroleum products, as catalysts for condensation reactions, BF3 and compounds are used as curing agents in epoxy resins. can be used as raw material for preparing optical fiber preforms. It is mainly used for ion implantation and doping in the production of semiconductor devices and integrated circuits. Antioxidant when casting magnesium and alloys.
