摘要： An embodiment of the present invention provides a method of preparing 2,5-furandimethylcarboxylate (FDMC), including preparing 2,5-furandimethylcarboxylate (FDMC) by subjecting a reaction mixture including 5-hydroxymethylfurfural (HMF), air, and an alcohol solvent to oxidative esterification in the presence of a gold (Au)-nanoparticle-supported catalyst, in which the gold (Au)-nanoparticle-supported catalyst includes a support and gold (Au) nanoparticles supported on the support.
