| Hazard Information | Back Directory | [Chemical Properties]
colourless fuming liquid | [General Description]
A colorless, fuming liquid with a pungent odor. Used to make other chemicals and in rockets. Very toxic by inhalation. Corrosive to metals and tissue. Will accelerate the burning of combustible material. If the containers are involved in a fire they may rupture violently and rocket. | [Air & Water Reactions]
Produces corrosive fumes in moist air. Reacts explosively upon contact with water. Very reactive, usually with conflagration [Merck, 11th ed. 1989]. Reaction with water is violent, oxygen being evolved, [Mellor 2 Supp. 1:172 1956]. | [Reactivity Profile]
Bromine pentafluoride an oxidizing agent. Is decomposed exothermically by water to hydrofluoric acid and other materials. Reacts with these other hydrogen-containing substances (among others) vigorously enough to cause a fire or explosion: acetic acid, ammonia, benzene, ethanol, hydrogen, hydrogen sulfide, methane, cork, grease paper, wax. Mixtures with acids, halogens, metal halides, metals, nonmetals, or metal oxides at ambient or slightly above ambient temperatures have resulted in violent reaction (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. Solutions of acetonitrile and 9% Bromine pentafluoride have been found to decompose violently at ambient temperatures. Mixtures of perchloryl perchlorate and Bromine pentafluoride form shock sensitive explosives. [Bretherick, 5th ed., 1995, p. 640]. | [Health Hazard]
Chemical is highly corrosive and toxic. Inhalation causes severe burns of mucous membrane. Ingestion causes severe burns of mouth. Contact with eyes or skin causes severe burns. | [Hazard]
Corrosive to skin and tissue. Explodes on
contact with water. Eye and upper respiratory tract
irritant.
| [Potential Exposure]
Bromine pentafluoride is used as an
oxidizer in liquid rocket propellant combinations; it may be
used in chemical synthesis. | [First aid]
If this chemical gets into the eyes, remove any
contact lenses at once and irrigate immediately for at least
15 minutes, occasionally lifting upper and lower lids. Seek
medical attention immediately. If this chemical contacts the
skin, remove contaminated clothing and wash immediately
with soap and water. Seek medical attention 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 chemical has been swallowed, get medical
attention. If victim is conscious, administer water or
milk. Do not induce vomiting. Medical observation is
recommended for 24 to 48 hours after breathing overexposure,
as pulmonary edema may be delayed. As first aid for
pulmonary edema, a doctor or authorized paramedic may
consider administering a drug or other inhalation therapy. | [Shipping]
UN1745 Bromine pentafluoride 5.1; Labels:
5.1—Oxidizer, 6.1—Poison Inhalation Hazard, 8—
Corrosive material, Inhalation Hazard Zone A. | [Incompatibilities]
A powerful oxidizer. Bromine pentafluoride
reacts with every known element except inert gases,
nitrogen, and oxygen. It reacts violently with water, acids,
acid fumes (releasing highly toxic fumes of bromine and
fluorine). Incompatible with halogens, arsenic, selenium,
alkaline halides, sulfur, iodine, glass, metallic halides, metal
oxides, and metals (except copper, stainless steel; nickel,
and Monel). Fire may result from contact with combustibles
or organic matter at room temperature, and contact of this
substance with water produces an explosion. Even under
mild conditions this substance attacks organic compounds
vigorously, often causing explosion. Decomposes in heat
above 460° C. | [Description]
Bromine pentafluoride is colorless to pale yellow liquid, with pungent odor. At temperatures above boilingpoint this chemical is a colorless gas. Molecularweight=174.92; Specific gravity (H2O:1)=2.48; Relative vapor density (air=1)=6.1; Boiling point=40.5℃;Freezing/Melting point=- 61℃; Vapor pressure 5328 mmHg at 20℃. Hazard Identification (based on NFPA-704 M Rating System): Health 4, Flammability 0,Reactivity 3 . Reacts explosively with water. | [Waste Disposal]
Allow gas to flow into mixed
caustic soda and slaked lime solution. Return unwanted
cylinders to supplier if possible. | [Physical properties]
Colorless to pale yellow liquid; fumes in air; density 2.466 g/mL at 25°C; boils at 40.8°C; decomposes above 460°C; solidifies at -60.5°C; reacts violently with water. | [Definition]
ChEBI: Bromine pentafluoride is an interhalogen compound. | [Preparation]
Bromine pentafluoride is prepared by fluorination of bromine at 200°C. The reaction is carried out in an iron or copper vessel. The halogens are diluted in nitrogen. | [Fire Hazard]
Noncombustible liquid; stable to heat, shock,
and electric spark. However, bromine penta-
fluoride is a highly reactive substance. It
reacts explosively with water, producing
toxic and corrosive fumes. It decomposes in
contact with acids, producing toxic fumes of
bromine and fluorine. The reaction is violent,
especially with concentrated nitric or sulfuric
acid.
Bromine pentafluoride reacts violently
with organic materials, such as carboxylic
acids, alcohols, ethers, hydrocarbons, grease,wax, and cellulose. Spontaneous flaming
and/or explosion can occur when mixed with
these or any other organic compound. Reac tions with metals in powder form and/or
upon warming can result in a violent explo sion. Ignition occurs under cold condition.
Violent reactions occur with metal halides,
oxides, and sulfides. Bromide pentafluo ride ignites when mixed with iodine and
explodes with chlorine on heating. Mixtures
of bromine pentafluoride with sulfur, phos phorus, and carbon ignite.
Avoid using water in the case of fire, since
the compound explodes with water. How ever, water may be used from a safe distance
to extinguish a fire involving large amounts
of combustible materials, and to keep the
fire- exposed containers cool. Fires involving
small amounts of combustible material may
be extinguished by CO2 or a dry chemical
(NFPA 1997). | [storage]
Color Code—Red Stripe: Flammability Hazard:Store separately from all other flammable materials. Priorto working with bromine pentafluoride you should betrained on its proper handling and storage. Store in tightlyclosed containers in a cool, well-ventilated area away from water, steam, acids, acid fumes, and combustibles. Metalcontainers involving the transfer of this chemical should begrounded and bonded. Drums must be equipped with selfclosing valves, pressure vacuum bungs, and flame arresters.Use only nonsparking tools and equipment, especially whenopening and closing containers of this chemical. Sources ofignition, such as smoking and open flames, are prohibitedwhere this chemical is used, handled, or stored in a mannerthat could create a potential fire or explosion hazard. SeeOSHA Standard 1910.104 and NFPA 43A Code for theStorage of Liquid and Solid Oxidizers for detailed handlingand storage regulations. | [Purification Methods]
Purify it via its KF complex, as described for chlorine trifluoride. [Kwasnik in Handbook of Preparative Inorganic Chemistry (Ed. Brauer) Academic Press Vol I pp 158-159 1963.] HIGHLY TOXIC. |
