Procedure
In a round flask, 2 mL of methyl cyanide (acetonitrile) as an organic solvent was introduced, 0.145 g (1 mmol) of 5-chloromethylfurfural (CMF, compound I) was dissolved in the organic solvent, 0.170 g (1 mmol) of 1-ethyl-3-methylimidazolium acetate was added to the solution, and then the mixed solution was reacted at normal pressure and room temperature for 5 minutes. After the reaction, the reaction product was extracted by the addition of a small amount of water (5 mL) and ethyl acetate (added twice by 20 mL) to obtain an organic layer. The obtained organic layer was concentrated under reduced pressure to obtain light yellow liquid 5-acetoxymethylfurfural (AcHMF, compound II). The yield thereof is 36%.
