| 摘 要： | 以1,4-丁基磺酸内酯、吡啶和三氟甲基磺酸为原料,采用两步法合成吡啶型离子液体,以离子液体为催化剂,质量分数30%的H2O2为氧化剂,对模拟油进行氧化-萃取脱硫研究。实验结果表明:10mL的模拟油在反应温度为50℃、反应时间为30min、离子液体加入质量为0.6g、H2O2加入体积为0.2mL时,模拟油的脱硫率达到94%。将脱硫后分离出的离子液体经过旋转蒸发仪处理后重复使用,使用5次后模拟油的脱硫率可达到70%。

Oxidation-Extraction Desulfurization by Pyridinium-Based Ionic Liquid |

| Abstract: | Base on the two-step method,ionic liquid BPy]CF3SO3]was synthesized from 1,4-Butane sultone,ridine trifluoromethane sulfonic acid and py.Oxidation-extraction desulfurization of model oil has been carried out with the ionic liquid as catalyst and 30% H2O2as the oxidant.Desulfurization rate of model oil could reach to 94%,when treating 10mL model oil with 0.6g ionic liquid,0.2mL H2O2at 50℃for 30min.After drying with rotary evaporator,the ionic liquid was regenerated for next-run use,and the desulfurization rate could be still as high as 70%after recycling 5-times. |
