Physical & Chemical Properties

Physical description & handling notes

• Boron trifluoride is a colorless gas with a pungent odor. It is toxic by inhalation. It is soluble in water and slowly hydrolyzed by cold water to give off hydrofluoric acid, a corrosive material. Its vapors are heavier than air. Prolonged exposure of the containers to fire or heat may result in their violent rupturing and rocketing.
• Colorless gas with a pungent, suffocating odor; Note: Forms dense white fumes in moist air. Shipped as a nonliquefied compressed gas; [NIOSH] Vapor density = 2.34 (heavier than air); [Burke, p. 100]
• COLOURLESS COMPRESSED GAS WITH PUNGENT ODOUR. FORMS WHITE FUMES IN MOIST AIR.
• Colorless gas with a pungent, suffocating odor.
• Colorless gas with a pungent, suffocating odor. [Note: Forms dense white fumes in moist air. Shipped as a nonliquefied compressed gas.]
• Colorless gas
