Selective transformation of carbohydrates to hydroxymethyl furfural with polyaniline-based catalysts

Selective transformation of carbohydrates to hydroxymethyl furfural with polyaniline-based catalysts Metal-free and efficient conversion of different carbohydrates to 5-hydroxymethyl furfural (HMF) with a novel PANI–GO catalyst has been successfully performed. Keywords Dehydration  Carbohydrates  Hydroxymethyl furfural  Polyanilines Biomass conversion Introduction With the depletion of fossil resources and the increase of environmental pollution, the efficient conversion of renewable biomass feedstock to valuable chemicals has attracted considerable attention from many scientists [1, 2], and the selective transformation of biomass-derived sugar compounds to furans has become a hot topic [3–5]. As a potential alternative route, the selective transformation of carbohydrates to 5-hydroxymethyl furfural (HMF) has been broadly investigated [6]; the catalytic dehydration of D-fructose is the most efficient approach [7, 8]. The obtained HMF had great potential to serve as a substitute for preparing non- petroleum-derived building blocks which have been used in the production of polyamide and more fine products [9]. Moreover, a high-density liquid fuel, 2,5- dimethylfuran (DMF), and polymeric monomer, funan-2,5-dicarboxylic acid (FDCA,) can also be synthesized from HMF via a simple hydrogenation and oxidation process [10, 11]. Thus, developing a novel and efficient catalytic system for the dehydration of carbohydrates to HMF is considered as a significant and promising method for the transformation of biomass feedstocks Research on Chemical Intermediates Springer Journals
