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3 0%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: 1 0mL的模拟油在反
应温度为5 0℃、 反应时间为3 0m i n、 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
9 4%。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7 0%。

Abstract: Base on the twostep method, ionic liquid \[BPy\]\[CF3SO3\] 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% H2O2 as the oxidant. Desulfurization rate of model oil could reach to 94%, when treating 10 mL model oil with 0.6 g ionic liquid, 0.2 mL H2O2 at 50 ℃ for 30 min. 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.

Key words: Oxidative desulfurization, Ionic liquid, Model oil, Dibenzothiophene, Regeneration
