| 摘 要： | 采用类似室温离子液体的低温氯化锌熔盐为反应介质，在稀酸的催化下纤维素可快速降解为葡萄糖，而后通过补充二甲亚砜与不同的氯化物金属盐催化剂，可以实现葡萄糖转化为5-羟甲基糠醛, 并研究了其降解过程中的分子机制，探讨了不同金属催化剂的影响，最终得到的HMF的最大产率为53%．

| Abstract: | The conversion of cellulose to 5-hydroxymethylfurfural (HMF) has been investigated by a one-pot consecutive reaction. At first, cellulose was depolymerised into glucose via a fast degradation of cellulose in molten ZnCl2 in the presence of hydrochloric acid, and the yield of glucose is 75% in 120 s at reaction temperature of 95 oC. Then, DMSO was used as solvent and different kinds of metal chloride were added as catalysts, and the conversion was carried out continuously at 110-130 oC for 0.5-4 h. The yield of HMF was 53% when CrCl3 were used as catalyst. The one-pot two steps conversion was carried out at atmosphere pressure, and it is a simple route to prepare HMF from lignocellulosic feedstock on a large scale. |
