<p>The purpose of the present invention is to provide a method for preparing 5-hydroxymethylfurfural (HMF) from a saccharide at a low cost under mild conditions. Attention has been paid to a reaction path for the preparation of HMF from a saccharide, said reaction path comprising both isomerization of glucose into fructose by means of an acid or a base, and subsequent dehydration of the fructose into HMF mainly by means of an acid. Specifically provided is a method which includes isomerizing glucose into fructose by means of a solid base catalyst and dehydrating the fructose into HMF by means of a solid acid catalyst having sulfonic acid groups. In this method, the solid base catalyst and the solid acid catalyst can coexist in the same reactor, though simultaneous addition of a liquid acid catalyst and a liquid base catalyst into the same reactor is impermissible.</p> |
