| | BROMINE TRIFLUORIDE Usage And Synthesis |
| Description | Bromine trifluoride is a noncombustible, colorless to gray-yellow fuming liquid with an extremely irritating odor. Molecular weight=136.9. Specific gravity(H2O:1)=2.8 at 20℃; Boiling point=135℃; Freezing/Melting point=8.8℃. Hazard Identification (based onNFPA-704 M Rating System): Health 4, Flammability 0,Reactivity 3 . Reacts with water, forming corrosive gas. | | Chemical Properties | fuming colourless or light yellow liquid, | | Chemical Properties | Bromine trifluoride is a noncombustible, colorless
to gray-yellow fuming liquid. Extremely irritating odor. | | Physical properties | 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. | | Uses | The commercial uses of this compound arevery limited. It is used as a solvent forfluorides. | | Uses | Solvent for fluorides. | | Preparation | Bromine trifluoride may be prepared by fluorination of bromine at 80°C. The halogen mixtures may be diluted in nitrogen or an inert gas. | | General Description | 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. | | Air & Water Reactions | Fumes in air. Reacts with water with explosive force, oxygen being evolved [Handbook of Chemistry and Physics]. | | Reactivity Profile | 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. | | Hazard | Corrosive to skin. Very reactive and dan-
gerous. | | Health Hazard | Inhalation causes severe irritation of upper respiratory system. Contact with liquid or vapor causes severe burns of eyes and can cause ulcers and blindness. Contact with skin causes severe burns. Ingestion causes severe burns of mucous membranes. | | Health Hazard | 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. | | Fire Hazard | Behavior in Fire: Forms very toxic and irritating fumes. | | Safety Profile | Poisonous and
corrosive. Very reactive, a powerful oxidizer.

agent and an electrolytic solvent. | | First aid | If this chemical gets into the eyes, remove anycontact lenses at once and irrigate immediately for at least30 min without stopping, occasionally lifting upper andlower lids. Seek medical attention immediately. If thischemical contacts the skin, remove contaminated clothingand wash immediately with soap and water. Seek medicalattention immediately. If this chemical has been inhaled,remove from exposure, begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR if heart action has stopped.Transfer promptly to a medical facility. When this chemicalhas been swallowed, get medical attention. If victim is conscious,administer water or milk. Do not induce vomiting.Medical observation is recommended for 24 48 h afterbreathing overexposure, as pulmonary edema may bedelayed. As first aid for pulmonary edema, a doctor orauthorized paramedic may consider administering a corticosteroid spray. | | storage | Color Code—Red Stripe: Flammability Hazard:Store separately from all other flammable materials.Bromine trifluoride must be stored to avoid contact withwater (which releases hydrogen fluoride gas), ammoniumhalides, antimony trioxide, antimony chloride, and solvents(such as ether, acetone, acetic acid, toluene, and so on),since violent reactions occur. Store in tightly closed containers in a cool, well-ventilated area away from organicand/or combustible materials (such as wood, cotton, andstraw), chloride and bromide salts, and many metals.Whenever bromine trifluoride is used, handled, manufactured,or stored, use explosion-proof electrical equipment and fittings. See OSHA Standard 1910.104 and NFPA 43ACode for the Storage of Liquid and Solid Oxidizers fordetailed handling and storage regulations. | | Shipping | UN1746 Bromine trifluoride, Hazard class 5.1;
Labels: 5.1—Oxidizer, 6.1—Poison Inhalation Hazard, 8—
Corrosive material, Inhalation Hazard Zone B. | | Incompatibilities | 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. |
