Phosphorus tribromide Usage And Synthesis
Chemical Properties(possibly hazy) liquid
UsesUsed in tests for skin corrosivity.
General DescriptionA colorless fuming liquid with a pungent odor. Corrosive to metals and tissue. Boiling point 347°F (175°C). Freezing point -40°F (-40°C).
Air & Water ReactionsFumes in air. Decomposed by water to form phosphoric acid and hydrobromic acid. Reaction with warm water is very rapid and may be violent [Mellor v.8. 1032 1940].
Reactivity ProfilePhosphorus tribromide reacts with oxidizing agents to generate heat and products that may be flammable, combustible, or otherwise reactive; the reactions may be violent. Forms complexes with potassium or sodium metal that explode when shocked. Drop wise addition to 3-phenylpropanol caused an explosion when stirring of the mixture was discontinued [Chem. Brit., 1974, 10, 101-102].
Health HazardInhalation causes severe irritation of nose, throat, and lungs. Ingestion causes burns of mouth and stomach. Contact with eyes or skin causes severe burns.
Safety ProfileProbably highly toxic. A corrosive irritant to the eyes, skin, and mucous membranes. Wdl react with water, steam, or acids to produce heat, toxic and corrosive fumes. Violent reaction or ignition with calcium hydroxide + sodium carbonate, phenylpropanol, sulfuric acid, oleum, fluorosulfuric acid, chlorosulfuric acid, 1,1,1 -tris(hydroxymethyl)methane, water, potassium, sodium, RuO4. When heated to decomposition it emits very toxic fumes of Brand POx. See also PHOSPHIDES and BROMIDES.
Purification MethodsIt is decomposed by moisture, it should be kept dry and is corrosive. Purify it by distillation through an efficient fractionating column [see Whitmore & Lux J Am Chem Soc 54 3451] in a slow stream of dry N2, i.e. under strictly dry conditions. [Gay & Maxson Inorg Synth II 147 1946, Org Synth Col Vol II 358 1943.] Dissolve it in CCl4, dry it over CaCl2, filter and distil it. Store it in sealed ampoules under N2 and keep it away from light. HARMFUL VAPOURS.
