Model Oil

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  model  oil  with  the  above  ionic liquid and with acetonitrile was also performed.  The thiophene extraction efficiencies of the ionic liquids and that of the control in both the oxidative and non-oxidative procedures were determined  by  means  of  gas  chromatography.  The  ionic  liquid  of  the  shortest  alkyl substituent chain length (R: C2), [EMIM] Br exhibited the highest extraction efficiency in the oxidative desulfurization of the model  oil; the extraction efficiency of [EMIM] Br was also observed  to  exceed  that  of  acetonitrile.  In  general,  the  oxidative  desulfurization  with  the above [RMIM]Br’s is apparently a more efficient method of thiophene removal from the model oil as compared to a non-oxidative procedure with the same extraction solvents. The extraction efficiency of [RMIM]Br’s was observed to decrease with the lengthening of the alkyl  substituent  chain.  The  same  trend  is  observed  in  the  non-oxidative  extractive desulfurization of the model oil. Recyclability analysis of [EMIM]Br showed that [EMIM]Br can be recycled thrice with no significant decrease in extraction efficiency.
