To develop cellulose-derived HMF production process, which includes multi-step reaction (cellulose hydrolysis, glucose isomerization and fructose dehydration), heterogeneous catalysts such as ion exchange resin and ionic liquid were employed as catalysts and solvent, respectively. It was found that sequential water addition was effective for selective glucose production via cellulose hydrolysis. It was revealed that alkali catalyst, which is normally effective for glucose isomerization in aqueous solution, became inactive in ionic liquid. Probably, this can be explained by strong interactions between alkali (or alkaline-earth) metal ion in heterogeneous catalysts and Cl- in ionic liquid (such as [Bmim][Cl]) such that active sites on the materials are poisoned. In addition, glucose isomerization into fructose is equilibrium reaction and fructose yield is limited at lower temperature because of the equilibrium constraint. To overcome these issues, direct production of HMF from glucose is effective and Lewis acid catalyst must be attempted. To accomplish energetically-favorable products separation and recycle of solvent, combination of liquid-liquid extraction with distillation would be appropriate and effective.

为了开发纤维素来源的HMF生产过程，其中包括多步反应（纤维素水解，葡萄糖异构化和果糖脱水），分别用作催化剂和离子液体的异质催化剂，分别用作催化剂和离子液体。发现顺序的水添加对于通过纤维素水解的选择性葡萄糖产生有效。据表明，在水溶液中通常对葡萄糖异构化有效的碱催化剂在离子液体中变得无活性。可能，这可以通过异质催化剂中的碱（或碱 - 地点）金属离子之间的强烈相互作用来解释，而离子液体中的Cl-（例如[BMIM] [CL]）中的Cl-使材料上的活性位点被中毒。另外，葡萄糖异构化在果糖中是平衡反应，由于平衡约束，果糖产量在较低的温度下受到限制。为了克服这些问题，从葡萄糖直接生产HMF是有效的，必须尝试尝试刘易斯酸催化剂。为了完成有力的产物分离和溶剂的回收，液态液体提取与蒸馏的结合将是适当有效的。
