Studies on Synthesis and Properties of Hydrophobic Brønsted Acidic Ionic Liquid

Article Preview

Abstract:

A hydrophobic Brønsted acidic ionic liquid 1-octyl-3-(butyl-4-sulfonate) imidazolium hydrogen sulfate ([BsImR₈][HSO₄]) was synthesized and characterized by fourier transform infrared (FT-IR), nuclear magnetic resonance (NMR), electron spray ionization mass spectrometry (ESI-MS) and thermogravimetry (TG). [BsImR₈][HSO₄] was used as an efficient catalyst for esterification of oleic acid with methanol to biodiesel. It was founded that [BsImR₈][HSO₄] exhibited high catalytic activity, which is near to that of H₂SO₄.It was ascribed to its strong Brønsted acidity. The catalyst could maintain high activity after five cycles of use.
