摘要

5-Chloromethylfurfural (5-CMF), a biomass-derived platform chemical with great potential applications, was synthesized by a novel method from sugars, using metal chlorides as catalysts in a deep eutectic solvent (DES). AlCl _(3) ·6H _(2) O was verified as the most effective catalyst among various metal chlorides, and provided a 5-CMF yield of 50.3% along with 8.1% 5-HMF yield at 120 °C in 5 h. By this green, mild and cost-effective approach, the dependence of 5-CMF production on the large amount and high concentration of hydrochloric acid in previous studies was eliminated.
