Description

General description

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

Application

1-Butyl-3-methylimidazolium tetrafluoroborate has been used as a solvent for the synthesis of zinc sulfide (ZnS) nanoparticles in the absence stabilizing agents or capping agents. It can also be used as an extractant for the removal of dibenzothiophene (DBS) from liquid fuels via extractive desulfurization.
