1-Butyl-3-methylimidazolium tetrafluoroborate Usage And Synthesis

description

1-Butyl-3-methylimidazolium hexafluorophosphate, also known as BMIM-PF6, is a viscous, colourless, hydrophobic and non-water-soluble ionic liquid with a melting point[1] of -8 °C. Together with 1-butyl-3-methylimidazolium tetrafluoroborate, BMIM-BF4, it is one of the most widely studied ionic liquids. It is known to very slowly decompose in the presence of water.

Uses

1-n-Butyl-3-methylimidazolium tetrafluoroborate is an ionic liquid used for various reactions such as hydrogenations, asymmetric hydrogenations proceed in higher enantioselectivity than in homogeneous phase. It is also used in Suzuki cross-coupling.

solubility

Miscible with acetone, acetonitrile, ethyl acetate, isopropyl alcohol and methylene chloride. Immiscible with hexane, toluene and water.

Physical properties

Clear yellowish-orange oil

Uses

1-Butyl-3-methylimidazolium tetrafluoroborate may be used as an extractant for the removal of dibenzothiophene (DBS) from liquid fuels via extractive desulfurization.

Uses

1-Butyl-3-methylimidazolium tetrafluoroborate ([BMIM]BF₄) can be used:??

• As a reaction medium for the preparation NH₄TiOF₃ mesocrystals, which are converted into TiO₂ based nanostructures.????????
• As a working fluid along with 2,2,2-trifluoroethanol in absorption heat pumps or chillers.???????
• As an electrolyte in lithium-ion batteries and double layer capacitors.

Uses

Solvent for organic reactions.

General Description

1-Butyl-3-methylimidazolium tetrafluoroborate is a high-purity ionic liquid (HPIL) with low water and halogen content.
