Removing sulfur compounds from petroleum is essential in mitigating harmful emissions linked to fuel combustion. Problematically, thiophenic that are readily present fossil fuels resist conventional desulfurization methods. Extractive (EDS) provides an attractive alternative can be selective for heterocyclic compounds, i.e., thiophene and its derivatives, through the choice of solvent employed. To this end, a burgeoning field has developed around use ionic liquids (ILs) given their ability fine-tuned with varying levels polarity solubility suit specific requirements process. Hundreds experimental studies featuring IL technologies have provided encouraging trends design more efficient extractants; however, conflicting data lack definitive understanding important solute–ion interactions presented challenges advancing field.
