| Abstract: | A carboxyl-functionalized ionic liquid,1-methyl-3-methylcarboxylate imidazolium tetrafluoroborate(cmmim]BF4),was applied as the catalyst and extractant in the oxidative desulfurization system for the removal of dibenzothiophene(DBT) in the presence of H2O2 in model oil.Several parameters including the amount of hydrogen peroxide,temperature and reaction time were investigated.The catalyst used shows a good activity with a DBT conversion of 100% at 60℃,O/S mol ratio 6 and the reaction time of 80min.The activity of ionic liquid cmmim]BF4 decreases little after recycling for 4 times. |
