Chemical name
Adduct of boron trifluoride (BF3)
and dimethyl ether (O(CH3)2)
Trade name
Boron trifluoride Dimethyl ether
Ingredient
Boron fluoride dimethyl ether,
boron trifluoride dimethyl ether
Chemical formula
BF₃X O(CH₃)₂
Molecular weight
113.88 g/mol
CAS No.
353-42-4
EINECS No.
206-532-1
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 in tank trucks is also possible.
Properties
When stored for relatively long periods it can turn dark in color without losing its application-related properties. On dilution with water, hydrolysis ensues with liberation of dimethyl ether. A corrosive, highly acidic mixture of boric acid, hydroxyfluoroboric acids and tetrafluoroboric acid is obtained. The vapors released in air are corrosive.
Due to its catalytic properties Boron trifluoride- Dimethyl ether reacts with numerous organic compounds.

Storage and transport
The product must be stored cool and dry in tightly sealed container or tank. 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.
Applications
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:
dimerization
trimerization
oligomerization
polymerization
rearrangement
alkylation
acylation
carbonylation
ring closure
reforming of paraffins
upgrading of lubricants and many others.
Safety
Highly flammable. Corrosive. Toxic. Exothermic reaction with water: reaction product dimethyl ether (extremely flammable).
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.
