Conversion of Fructose to 5-hydroxymethylfurfural Catalyzed by Coaled Carbon-Based Solid Acid

Article Preview

Abstract:

Coaled carbon-based solid acid (Coal-SO3H) was prepared by sulfonating ultra-low ash Taixi coal and characterized by XPS, IR and PXRD. It was used as a new, efficient and recyclable catalyst for fructose dehydration to form 5-hydroxymethylfurfural (5-HMF) in dimethyl sulfoxide (DMSO). Reaction time, temperature and catalyst amounts were investigated respectively. The results showed that 81.6 % yield of 5-HMF achieved in dimethyl sulfoxide (DMSO) at 140 °C after 140min using the Coal-SO3H as catalyst. The ash, carbonization temperature and sulfonated way which could influence the catalyst performance for preparing 5-HMF had been investgated.
