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.
Properties
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.

It can be easily dosed with gear pumps or membrane pumps.
Examples of its uses in the chemical, petrochemical and pharmaceutical industries include：
dimerization
trimerization
oligomerization
polymerization
rearrangement
alkylation
acylation
carbonylation
ring closure
reforming of paraffins
upgrading of lubricants and many others.
