Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of preparing 2,5-furandimethylcarboxylate (FDMC), comprising: preparing 2,5-furandimethylcarboxylate (FDMC) by subjecting a reaction mixture comprising 5-hydroxymethylfurfural (HMF), air and an alcohol solvent to oxidative esterification using a gold (Au)-nanoparticles/hydroxyapatite (HAP)-supported catalyst, wherein the HAP is used as a support on which the gold (Au) nanoparticles are supported, wherein the oxidative esterification is carried out by entering air and maintaining an air pressure of 1.7 to 3.1 MPa. 2. The method of claim 1 , wherein an amount of the gold (Au) nanoparticles is 0.5 wt % to 10 wt % based on 100 wt % of the gold-nanoparticles/HAP-supported catalyst. 3. The method of claim 1 , wherein a gold content of the HAP supported catalyst is 0.5 mol to 2.0 mol based on 100 mol of the hydroxymethylfurfural (HMF). 4. The method of claim 1 , wherein the alcohol solvent is methanol. 5. The method of claim 1 , wherein the oxidative esterification is carried out at a temperature of 110° C. to 150° C. for 3 hr to 12 hr.
