Abstract

76% Yield of levulinic acid was obtained from fructose conversion catalyzed by acidic ionic liquid in water. The chemical structures and morphologies of humin byproduct were investigated, indicating three stages of transition for the first time. At the early stage, 5-hydroxymethylfurfural (HMF) intermediate from fructose dehydration can take part in humin formation through two sites. When HMF intermediate was completely converted, humins can react further on aldehyde groups, as evidenced by disappearance of 2-formylfuran rings. If the reaction time was long enough, humins can undergo subsequent aromatization, with the furan rings reduced and the C=C groups increased.
