General description

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

Application

Ionic Liquids for Catalysis
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.

Ionic Liquids for Catalysis

Ionic Liquids have been thoroughly investigated as solvents in most types of catalytic reactions. Their merit lies in the ease with which their physical–chemical properties can be tuned by varying either the anion, the cation, or its substitution pattern.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
