▎ 摘  要

NOVELTY - Preparing 2,5-diformylfuran through a three-step cascade reaction of glucose involves adjusting the pH to 3 5 in the glucose solution and adding a heterogeneous Lewis acid catalyst to react at 120-180 degrees C to obtain a fructose solution. The heterogeneous Lewis acid catalyst is a TiO2 catalyst containing anatase phase and rutile phase. The graphene oxide catalyst is added to the fructose solution and reacted at 120-200 C to obtain 2,5-diformyl furan. The graphene oxide catalyst is made by sulfonating graphene oxide sheets and supporting precious metals. USE - Method for preparing 2,5-diformylfuran through a three-step cascade reaction of glucose.
