Green process for dehydration of fructose into 5-hydroxymethylfurfural with ion exchange resin catalyst
The compound 5-hydroxymethylfurfural (5-HMF) can be a monomer for future sustainable polymers provided an efficient dehydration method from biomass-derived fructose can be developed. In this work, the use of ion exchange resin catalysts, rather than strong acids are considered in developing a green process. Tworeaction solvent mixtures, acetone-water and acetone-dimethylsulfoxide (DMSO), were considered in this study.The addition of acetone to water not only increased reaction rate of fructose dehydration, but also suppressed 5-HMF decomposition into levulinic acid and formic acid, and resulted in 5-HMF yields of above 70 % at 150 ℃.The combination of acetone and DMSO solvent also promoted the formation of 5-HMF from fructose with a high 5-HMF selectivity of more than 90 % for almost complete fructose conversion. Considering the high selectivities and conversions obtained with the acetone-DMSO solvent mixture, a green process is proposed for producing 5-HMF from fructose using CO2 and acetone as internal recycle solvents. Compared with water and pure DMSO solvent, the combination of low boiling point of acetone with water or DMSO used as reaction media, not only gives highly selective 5-HMF formation, but also improves the separation efficiency.
