Name:Boron trifluoride tetrahydrofuran (BF3-THF)

Name:Boron trifluoride tetrahydrofuran (BF3-THF)

Molecular Formula : BF3.C4H8O

Molecular Weight : 139.91


When stored for relatively long periods Boron trifluoride-Tetrahydrofuran can turn dark in color without losing its application-related properties. On dilution with water, hydrolysis ensues with liberation of tetrahydrofuran. A corrosive, highly acidic mixture of boric acid, hydroxyfluoroboric acids and tetrafluoroboric acid is produced. 
The vapors released into the air are corrosive. 
Due to its catalytic properties Boron trifluoride-Tetrahydrofuran reacts with numerous organic compounds.
