Abstract
The present disclosure provides a preparing method for 5-alkoxymethylfurfural, including steps of (a) preparing fructose, (b) mixing the fructose, an organic acid catalyst, and an organic solvent, thereby preparing mixing solution, and (c) heating the mixing solution, thereby preparing 5-alkoxymethylfurfural. Therefore, 5-alkoxymethylfurfural may be effectively prepared without by-products from fructose.
Claims7
A preparing method for 5-alkoxymethylfurfural, wherein fructose is added to and reacts with an organic solvent under an organic acid catalyst, thereby obtaining 5-alkoxymethylfurfural,
- wherein the organic acid catalyst is acetic acid,
- wherein the acetic acid is added in an amount of 1 part by weight to 30 parts by weight with respect to 100 parts by weight of fructose.
A preparing method for 5-alkoxymethylfurfural, comprising steps of:
- (a) preparing fructose;
- (b) mixing the fructose, an organic acid catalyst, and an organic solvent, thereby preparing mixing solution;
- and
- (c) heating the mixing solution, thereby preparing 5-alkoxymethylfurfural,
- wherein the organic acid catalyst is acetic acid,
- wherein the acetic acid is added in an amount of 1 part by weight to 30 carts by weight with respect to 100 parts by weight of fructose.
A method of preparing 2,5-furandicarboxylic acid comprising first preparing 5-alkoxymethylfurfural, wherein fructose is added to and reacts with an organic solvent under an organic acid catalyst wherein the organic acid catalyst is acetic acid, wherein the acetic acid is added in an amount of 1 part by weight to 30 parts by weight with respect to 100 parts by weight of fructose thereby obtaining 5-alkoxymethylfurfural, followed by using the 5-alkoxymethylfurfural to prepare 2,5-furandicarboxylic acid.
