Abstract:
？inthisresearch,1-butyl-pyridiniumtetrafluoroborate([c4py][bf4]-)waspreparedbyionexchangemethodandwascharacterizedby1h-nmr,13c-nmr,andft-irtechniques.thesynthesizedionicliquidwasusedforremovalofdibenzothiopheneasatypicalorganosulfurpollutantfromorganicmedium.theeffectofdifferentparametersontheextractionefficiencywasstudiedandoptimized.attheoptimizedconditions,97.68%ofdibenzothiophenewasextractedfrom1000mg/ln-hexanesolution.theextractionefficiencyobtainedinthisworkwashigherthanthepreviousreportedvalues.thedesulfurizationreactionwaskineticallyfollowedthesecondordermechanism.theionicliquidwasreusableandafterfourregenerationcycles97%ofitsoriginalextractionefficiencywasretained.
