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 investigated 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/VOIL being 1:1 at room temperature and atmosphere. The extraction ability of ionic liquid decreases only slightly after 6 cycles of reuse. (CPL-TBAB)/0.8CuCl2·2H2O 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.
