摘要: 分别以N-甲基咪唑和吡啶为阳离子,合成了10种通式为CnMimNTf2(n=2,3,4,5,6)和CnPyNTf2
(n=2,3,4,5,6)的双三氟甲基磺酰亚胺类离子液体;并以离子液体为萃取剂,以质量分数35%的H2O2 为氧化剂,考察了各离子液体与H2O2 组成的氧化体系对模拟油品中含硫化合物噻吩的氧化萃取能力,比较了10种离子液体的一次萃取效果,同时考察了反应温度、反应时间、剂油体积比以及氧化剂用量等因素对脱硫率的影响。结果表明,在反应温度60℃、反应时间1h、V(离子液体)/V(模型油)/V(氧化剂)=1∶30∶1条件下,反应体系对含硫质量分数为1146µg/g的模型油一次萃取脱硫率可达65%左右。

Abstract: Take N-methyl imdazole and pyridine as cation,a series of CnMimNTf2(n=2,3,4,5,6) and CnPyNTf2 (n=2,3,4,5,6) ionic liquids were synthesized.The ionic liquids were applied as extractant for model oil desulfurization experiments,with the use of hydrogen peroxide(35%)as oxdant.The extraction ability of ionic liquids towards thiophenein the model oil were studied.The results were compared under different reaction conditions such as reaction time,temperature, the ratio of oil,extractant and the amount of oxidant.The data indicates that,when V (ILs)/V (oil)/V (oxidant)=1∶30∶1 with 1 hour of reaction time at 60℃,the sulfur removal rate can reach to 65% for the model oil which 1146µg/g of original sulfur concentration.
