Abstract

An object of the present invention is to provide a method for producing 5-hydroxymethyl-2-furfural (5-HMF) suitable for industrial-scale production and a novel catalyst composition for use in synthesizing 5-HMF. The present invention provides a method for producing 5-HMF comprising performing a dehydration reaction of a carbohydrate comprising a hexose as a constituent sugar or a derivative thereof by using activated carbon as a catalyst; and a catalyst composition for use in the reaction for producing 5-HMF from a carbohydrate comprising a hexose as a constituent sugar through a dehydration reaction, the catalyst composition comprising activated carbon.

Claims

1. A method for producing 5-hydroxymethyl-2-furfural, comprising performing a dehydration reaction of a carbohydrate comprising a hexose as a constituent sugar or a derivative thereof by using activated carbon as a catalyst to thereby produce said 5-hydroxymethyl-2-furfural.

3. The method of claim 1, further comprising producing 2,5-furandicarboxylic acid or an ester thereof by subjecting said 5-hydroxymethyl-2-furfural to an oxidation reaction to thereby produce said 2,5-furandicarboxylic acid or an ester thereof.

4. The method of claim 3, further comprising producing a copolymer by copolymerizing the 2,5-furandicarboxylic acid or ester thereof with a different copolymerizable monomer.

5. The method according to claim 4, wherein the different copolymerizable monomer is ethylene glycol and the produced copolymer is polyethylene furanoate.

6. The method of claim 1, further comprising producing a pharmaceutical or food product by optionally derivatizing the 5-hydroxymethyl-2-furfural and blending the 5-hydroxymethyl-2-furfural or derivative thereof.

2. A method for producing a carbohydrate composition comprising 5-hydroxymethyl-2-furfural, comprising heating a carbohydrate composition comprising one or more selected from the group consisting of carbohydrates comprising a hexose as a constituent sugar and derivatives thereof in the presence of activated carbon at a temperature of 100°

C. to 400°

C. to thereby produce said carbohydrate composition comprising 5-hydroxymethyl-2-furfural.

8. The method of claim 2, further comprising producing 2,5-furandicarboxylic acid or an ester thereof by subjecting said 5-hydroxymethyl-2-furfural to an oxidation reaction to thereby produce said 2,5-furandicarboxylic acid or an ester thereof.

9. The method of claim 8, further comprising producing a copolymer by copolymerizing the 2,5-furandicarboxylic acid or ester thereof with a different copolymerizable monomer.

10. The method of claim 9, wherein the different copolymerizable monomer is ethylene glycol and the produced copolymer is polyethylene furanoate.

11. The method of claim 2, further comprising producing a pharmaceutical or food product by optionally derivatizing the 5-hydroxymethyl-2-furfural and blending the 5-hydroxymethyl-2-furfural or derivative thereof.

7. A catalyst composition for use in the reaction for producing 5-hydroxymethyl-2-furfural from a carbohydrate comprising a hexose as a constituent sugar or a derivative thereof through a dehydration reaction, the catalyst composition comprising activated carbon.
