摘要（英）：

The invention discloses a method for preparing 2,5-difuralehyde from 5-hydroxymethyl furfural through dehydrogenation. The method comprises the following steps: putting 5-hydroxymethyl furfural, styrene, a catalyst and an organic solvent into a reactor, performing mechanical stirring in a nitrogen atmosphere, and performing a reaction for 5-24 hours at 100-150 DEG C, so as to obtain a product 2,5-difuralehyde, wherein the catalyst is a supported metal catalyst, the catalyst comprises an active metal, a carrier and an aid, the active metal is Cu, the aid is Ni, and the catalyst carrier is gamma-Al2O3, TiO2, CeO2, MgO, SiO2, ZrO2 or activated carbon. The invention adopts a catalytic dehydrogenation method, the metal catalyst is good in catalysis performance, the conversion rate of the 5-hydroxymethyl furfural is up to 58.0% at most, and the yield of the 2,5-difuralehyde is up to 40.4% at most.
