Method for preparing fructose by selective isomerization of glucose

The invention discloses a method for preparing fructose by selective isomerization of glucose. The method for preparing the fructose by the selective isomerization of the glucose adopts supported catalysts and non-supported catalysts which are high in reaction activity, few in byproduct yield and high in selectivity; and thus, yield of products as well as selectivity of fructose are improved. Themethod for preparing the fructose by the selective isomerization of the glucose requires no addition of of co-catalysts or organic solvents; instead, water, which is easy to obtain, environmentally friendly and non-toxic, is used as the solvent. Thus, the method has the advantages of being simple in synthesis processes, low in production cost, environmentally friendly, non-toxic and so on. 本发明提出了一种由葡萄糖选择异构制备果糖的方法，采用反应活性高、副产物少、选择性高的负载型和非负载型催化剂，提高了产物的产率及果糖的选择性。本发明不需要添加助催化剂及有机溶剂，反应溶剂为水，易获取且环保无毒，并且具有合成工艺简单、生成成本低、环保无毒等优点。
