摘　　要：合成了5种季铵盐类金属基离子液体(CPL-TBAB)/MCln(M=Ni,Cu,Co,Zn,Fe),分别考察了其对模型油的萃取脱硫效果.结果表明(CPL-TBAB)/CuCl2?2H2O对模型油的萃取脱硫效果最好.并确定了较佳萃取脱硫工艺条件为:CPL-TBAB与CuCl2?2H2O物质的量比为1∶0.8,剂油比VIL/VOIL为1∶1时,常温常压下,(CPL-TBAB)/0.8CuCl2?2H2O对模型油中二苯并噻吩(DBT)的萃取脱除率可以达到97.10%.重复使用6次后(CPL-TBAB)/0.8CuCl2?2H2O的脱硫率只有略微下降.(CPL-TBAB)/0.8CuCl2?2H2O对不同含硫化合物和真实柴油均有较好的萃取脱硫效果,对真实柴油的单程萃取脱硫率可以达到75.59%.所研制的离子液体是一种具有工业应用价值的脱硫萃取剂.Five metal-based hyamine ionic liquids （CPL-TBAB）/MCln （M=Ni, Cu, Co, Zn, Fe） were synthesized and inves- tigated in extractive desulfurization of model oil. The result indicated that （CPL-TBAB）/CuCl2·2H2O was superior to other ionic liquids for the extraction desulfurization. The removal ratio of dibenzothiophene （DBT） can be up to 97.10% under the optimal reaction conditions having the suitable molar ratio of CPL-TBAB to CuCl2·2H2O being 1 ： 0.8 and VIL/Vo]L being 1 ： 1 at room temperature and atmosphere. The extraction ability of ionic liquid decreases only slightly after 6 cycles of reuse. （CPL-TBAB）/0.SCuCl2·2H2O showed an excellent extraction ability for different sulfur compounds model oil and real diesel The single extractive desulfurization removal ratio of real diesel was 75.59%. These results demonstrate that this metal-based ionic liquid is a promising extractive desulfurization agent.
