Provided is a method for preparing 5-hydroxymethyl-2-furfural using an acid catalyst in the presence of an ethylene glycol-based solvent. The method for preparing the 5-hydroxymethyl-2-furfural involves using a linear or cyclic ethylene glycol-based compound as a solvent and producing the 5-hydroxymethyl-2-furfural from fructose, in the presence of the acid catalyst, thereby reducing the dependency on petroleum in response to greenhouse gas emission regulations. Also, a high yield of the 5-hydroxymethyl-2-furfural can be obtained from fructose, and the solvent and the catalyst can be efficiently separated, collected, and reused after a reaction has completed.
A method for preparing 5-hydroxymethyl-2-furfural, comprising converting fructose into 5-hydroxymethyl-2-furfural in presence of an acid catalyst in a linear ethylene glycol-based compound as a solvent, wherein the acid catalyst is a solid acid catalyst and is structured to have an organic or inorganic support to which a Bronsted acid or a Lewis acid is linked as a functional group, wherein the linear ethylene glycol-based compound is represented by the following Structural Formula 1:
