化学的特性
Bromine trifluoride is a noncombustible, colorless
to gray-yellow fuming liquid. Extremely irritating odor.
物理的性質
Colorless liquid; hygroscopic; density 2.803 g/mL; boils at 125.8°C; solidifies at 8.8°C; vapor pressure 8 torr at 21°C; decomposes violently in water.
使用
Solvent for fluorides.
製造方法
Bromine trifluoride may be prepared by fluorination of bromine at 80°C. The halogen mixtures may be diluted in nitrogen or an inert gas.
一般的な説明
A colorless to yellow, fuming liquid with a pungent odor. Solidifies at 48°F. Very toxic by inhalation and corrosive to metals and tissue. Containers exposed to prolonged heat may violently rupture and rocket.
空気と水の反応
Fumes in air. Reacts with water with explosive force, oxygen being evolved [Handbook of Chemistry and Physics].
反応プロフィール
BROMINE TRIFLUORIDE is a very reactive oxidizing agent. Reacts violently on contact with water to evolve oxygen. Accelerates the burning of combustible material. Mixing with the following hydrogen-containing substances is likely to cause a fire or explosion: acetic acid, ammonia, benzene, ethanol, 2-pentanone, hydrogen, hydrogen sulfide, methane, cork, grease paper , wax. Mixing with acids, halogens, ammonium halides, metal halides, metals, nonmetals, or metal oxides at ambient or slightly above ambient temperatures has resulted in violent reactions. Specifically, reacts dangerously with nitric acid, sulfuric acid, chlorine, iodine, ammonium chloride, potassium iodide, boron powder, selenium, tellurium, aluminum powder, bismuth, cobalt powder, iron powder, arsenic, nickel powder, chromium trioxide, charcoal, red phosphorus, sulfur dioxide, magnesium oxide.
危険性
Corrosive to skin. Very reactive and dan-
gerous.
健康ハザード
The vapors of bromine trifluoride are highlyirritating to the eyes, skin, and mucousmembranes. Upon contact with the skin, theliquid can cause severe burns. The toxicitydata for this compound are not available.
火災危険
Behavior in Fire: Forms very toxic and irritating fumes.

agent and an electrolytic solvent.
輸送方法
UN1746 Bromine trifluoride, Hazard class 5.1;
Labels: 5.1—Oxidizer, 6.1—Poison Inhalation Hazard, 8—
Corrosive material, Inhalation Hazard Zone B.
不和合性
A powerful oxidizer; highly reactive and
a dangerous explosion hazard. Contact with water or other
hydrogen containing materials forms hydrogen fluoride gas.
Reacts with almost all elements except for inert gases.
Violent reaction with reducing agents; organic materials;
strong acids; strong bases; halogens, salts (antimony salts),
metal oxides; and many other materials. Attacks some plastics,
rubber, or coatings.
