| Abstract: | A water stable Brφnsted acid ionic liquid with alkane sulfonic acid groups was directly synthesized under ultrasonic irradiation and characterized by nuclear magnetic resonance(NMR).The experimental results showed that the synthesis under ultrasonic irradiation featured simple operation, mild condition, short reaction time and higher yield. The yield of ionic liquids of 92% was attained under ultrasonic irradiation time 120 min, ultrasonic power 200 W and irradiation temperature 30 ℃. |
