Boron Trifluoride

CAS RN:7637-07-2

Reactivities / Incompatibilities

Boron trifluoride reacts with incandescence when heated with alkali metals or alkaline earth metals, except magnesium.

Ethyl, isopropyl, butyl, benzyl, and triphenylmethyl nitrates in contact with ... boron trifluoride interact violently (after an induction period of up to several hr) with gas evolution.

The reaction of calcium oxide and boron trifluoride forms a fused mass after warming.

Hydrolyzes to produce boric acid, hydrofluoric acid, and fluoboric acid. Catalyst for many polymerization reactions.

With anhydrous calcium oxide or magnesium oxide, the metal fluoride and the volatile boron oxyfluoride are formed.

Aluminum chloride or aluminum bromide react with boron trifluoride when gently heated to yield boron halide and aluminum fluoride.

Boron trifluoride, (electrophilic), acts as an acid catalyst for esterification, nitrations, oxidations, reductions, and halogenations.

Alkali and alkaline earth metals reduce boron trifluoride to elemental boron and the metal fluoride.

Boron trifluoride reacts with slaked lime; calcium borate and fluoroborate are formed with evolution of heat.

Mono- and di- hydroxyfluoroboric acids are formed very rapidly when boron trifluoride contacts water contained in a vessel.

Interaction of ... /hexafluorisopropylideneaminolithium/ with a range of chloro- and fluoro-derivatives of boron ... during warming to 25 deg C tended to be violently exothermic in absence of solvent.

Alkali metals, calcium oxide [Note: Hydrolyzes in moist air or hot water to form boric acid, hydrogen fluoride and fluoboric acid].

It is a highly reactive gas with fire-retardant and antioxidant properties. When exposed to air, boron trifluoride forms a white fume.

Reacts violently with metals such as sodium, potassium and calcium, and with alkyl nitrates. Attacks many metals in presence of water.

The trihalides react with water, lower alcohols, hydrogen sulfide, alkyl mercaptans, ammonia, primary and secondary amines, phosphine, and arsine, liberating hydrogen halide in each case. /Boron trihalides/

The boron halides react violently with ammonia. /Boron halides/

Boron halides react violently with water, and, particularly if there is a deficiency of water, a violent explosion may result. /Boron halides/

Boron halides are reduced by active metals, metal hydrides, and hydrogen. Reaction with the alkali and alkaline earth metals at elevated temperature yields elemental boron and the metal halide. /Boron halides/

Water reactive. Hydrolyzes to produce boric acid, hydrofluoric acid, and fluoboric acid. Catalyst for many polymerization reactions. Incompatible with many active metals.
