Abstract

The effects of the homogeneous catalysts (H₂SO₄ and NaOH) and heterogeneous catalysts (TiO₂ and ZrO₂) on glucose reactions were examined in hot compressed water (473 K) by a batch-type reactor. From the homogeneous catalyst studies, we confirmed that the acid catalyst promoted dehydration, while isomerization of glucose to fructose was catalyzed by alkali. Anatase TiO₂ was found to act as an acid catalyst to promote formation of 5-hydroxymethylfuraldehyde (HMF). Zirconia (ZrO₂) was a base catalyst to promote the isomerization of glucose. The effects of the additives were also confirmed through fructose reactions.
