A one-pot conversion of sugars into 2,5-furandicarboxylic acid (FDCA) is demonstrated in a triphasic system: tetraethylammonium bromide (TEAB) or watermethyl isobutyl ketone (MIBK)water. In this reaction, sugars are first converted into 5-hydroxymethylfurfural (HMF) in TEAB or water (PhaseI). The HMF in PhaseI is then extracted to MIBK (PhaseII) and transferred to water (PhaseIII), where HMF is converted into FDCA. PhaseII plays multiple roles: as a bridge for HMF extraction, transportation and purification. Overall FDCA yields of 78% and 50% are achieved from fructose and glucose respectively.
