Abstract:

An efficient process for preparation of 5-hydroxymethylfurfuralHMFfrom glucose was developed with ionic liquid 1-butyl-3-methyl imidazolium chloride[BMIM][Cl]as solvent and CrCl3 as catalyst. A HMF yield of above 70% could be obtained at 130 in 20 min. Recycle of the ionic liquid and CrCl3 demonstrated constant activity after 5 cycles of use.

摘要:

以绿色溶剂离子液体1-丁基-3-甲基咪唑氯盐([BMIM]Cl)作为溶剂,六水合氯化铬(CrCl3·6H2O)为催化剂,研究了最重要的生物质衍生糖类葡萄糖向平台化合物5-羟甲基糠醛(HMF)的转化。该催化反应体系十分有效,在130 下反应20 minHMF的产率可达到70%以上。并且该催化体系可以循环使用,经过5次的重复使用后仍保持稳定的活性。
