| Abstract: | A sulfonic acidic ionic liquid TEA-SO3H] was synthesized and the 5-methyl-2-propionylfuran was prepared from 2-methylfuran and propionic anhydride by the Friedel-Crafts acylation reaction.The results showed that the catalytic performance of the TEA-SO3H] could be much better than that of the concentrated phosphoric acid and polyphosphate.The ionic liquid could be recycled for more than four times without apparent decrease in catalytic activity. |
