Abstract:The oxidative desulfurization of model oil (hexane solution of thiophene) was carried out at room temperature in a two-step method involving: 1) the acetic acid catalyzed oxidation of thiophene with hydrogen peroxide and 2) the subsequent extraction of the oxidized products with three 1-alkyl-3-methylimidazolium bromide [RMIM]Br ionic liquids of varying alkyl substituent R chain length (R: C2, C4, C6) and with acetonitrile as control. For purposes of comparison, a non-oxidative extractive desulfurization of mo… Show more
