超声波辅助法一步合成B酸离子液体
One-step synthesis of BrΦnsted acidic ionic liquids under ultrasonic irradiation
【摘要】 采用超声波辅助法一步合成了对水稳定性好和带—SO3H官能团的吡啶磺酸类B酸离子液体,用核磁共振(NMR)对制备的离子液体进行表征。结果表明,超声波辐射法具有操作简单、条件温和、反应时间短和收率高等优点。在超声辐射时间120 min、超声功率200 W和超声温度30℃条件下,离子液体收率达92%。
【Abstract】 A water-stable Brφnsted acid ionic liquid with alkane sulfonic acid groups was directly synthe- sized under ultrasonic irradiation and characterized by nuclear magnetic resonance (NMR).The experi- mental results showed that the synthesis under ultrasonic irradiation featured simple operation,mild con- dition,short reaction time and higher yield.The yield of ionic liquids of 92% was attained under ultra- sonic irradiation time 120 min,ultrasonic power 200 W and irradiation temperature 30 ℃.
