Description
Fuming liquid; [CAMEO] Stable but highly flammable, brown liquid; [ACGIH]
Sources/Uses
Boron trifluoride ethers are effective reagents used as a source of boron trifluoride in the production of semiconductors and organic compounds; [ACGIH] Used as an esterification reagent for fats and oils; in breeder reactor control rods; [HSDB] Used as a catalyst in chemical reactions; [CAMEO]
Comments
TLV Basis = respiratory tract irritation and pneumonitis; "Boron trifluoride is the key toxic exposure for workers handling or producing these materials." Reacts exothermically with water to release highly flammable ethers and corrosive boron trifluoride hydrates; [ACGIH] Corrosive to the skin; [Quick CPC] A strong skin, eye, and respiratory tract irritant; [HSDB] Very toxic by inhalation; [CAMEO] Reacts violently with water; [MSDSonline] See "Boron trifluoride."
