| Abstract: | The acetic acid-based ionic liquid was synthesized from acetic acid and methylimidazole by synthetic principle of ionic liquid.The ionic liquid has functions of both phase-transfer catalysts and extractant.In this paper,reaction mechanism of ionic liquid in oxidative desulfurization of simulated oil was introduced.The results show that when the reaction temperature is 80 ℃,reaction time is 30 min,the volume of model oil,ionic liquid and hydrogen peroxide is 10 mL respectively,the best desulfurization effect can be gained,the removal rate of thiophene in simu-lated oil may reach 73%. |
