Brownish, viscous liquid with a pungent odor, which fumes on contact with air and has a boron trifluoride content of at least 48 wt.%.
Adduct of boron trifluoride (BF3)
and tetrahydrofuran (C4H8O)
BF3X C4H 8 O
Boron trifluoride： 7637-07-2
Boron trifluoride： 231-569-5
Form supplied and packaging
Supplied in 200 l sheet steel drums with HDPE inner lining and in 60 l metal drums with HDPE inner lining. Supply in small containers and tanks is also possible.
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.

Storage and transport
The product must be stored cool and dry in tightly sealed container or tank in a cool, dry place. Storage tanks must be drained at regular intervals, washed out and inspected. Tanks that have been washed out must be refilled only when they are completely dry. When stored or transported in pressure-resistant tanks the product can be kept under an atmosphere of dry nitrogen.
For selective reaction control in numerous organic reactions, primarily as a catalyst or cocatalyst.
It can be easily dosed with gear pumps or membrane pumps.
Examples of its uses in the chemical, petrochemical and pharmaceutical industries include：
reforming of paraffins
upgrading of lubricants and many others.
During the handling of these products the data and reference in the safety data sheet are to be considered. In addition the necessary caution and good industrial hygiene while handling chemicals have to been kept.
