One-pot conversion of fructose into valuable 5-hydroxymethyl-2-furaldehyde (5-HMF) was investigated under a deep eutectic solvent-biphasic system. The role of ChCl, as an inexpensive and safe quaternary ammonium salt, was clearly found to be significant in the reaction. It improved the yield of 5-HMF from fructose dehydration and suppressed the side reactions as well. In addition, the deep eutectic solvent system exhibited a good recyclability with only a small decrease in the 5-HMF yield, while ChCl could be easily recrystallized in the presence of acetonitrile (ACN) (for 5 cycles) or tetrahydrofuran (THF) (for 2 cycles). This research provides a green way for the 5-HMF production via a reusable-biphasic process.

环保双相法将果糖催化转化为5-HMF

在深共熔溶剂-双相体系下，研究了果糖一锅转化为有价值的5-羟甲基-2-糠醛（5-HMF）的过程。清楚地发现，ChCl作为廉价和安全的季铵盐，在反应中起着重要的作用。它提高了果糖脱水产生的5-HMF的产率，并且还抑制了副反应。此外，深共晶溶剂体系显示出良好的可回收性，而5-HMF收率仅小幅下降，而ChCl在乙腈（ACN）（5个循环）或四氢呋喃（THF）的存在下很容易重结晶。 2个周期）。这项研究提供了5-HMF生产绿色的方式通过一个可重复使用的，双相的过程。
