【摘要】 采用两步法合成了5种离子液体,然后通过噻吩及柴油中其他典型化合物在不同结构离子液体中溶解度的测定,考察了离子液体的结构对典型硫化物的选择性的影响和离子液体对模型柴油、典型柴油的萃取脱硫效果。结果表明,辛基吡啶四氟硼酸盐对噻吩硫化物的选择性最好,其萃取脱硫效果最优。更多还原

【Abstract】 Five kinds ionic liquids were synthesized by the well-established procedures.The effects of ionic liquids structures on selectivity of sulfur compounds and the extractive desulfurization result for model and typical diesel fuel were studied by dissolubility testing of thiophene and other compounds in ionic liquids with different structures.The results show that [OcPy][BF4] is good extraction absorbent in desulfurization of diesel fuel,which displays high selectivity toward thiophene.更多还原
