We propose an integrated strategy for the production of 2,5-furandicarboxylic acid (FDCA) from fructose. In this process, fructose is first dehydrated to hydroxymethylfurfural (HMF) at high yield (70%) using a gamma-valerolactone (GVL)/H2O solvent system. HMF is then oxidized to FDCA over a Pt/C catalyst with 93% yield. The advantage of our system is the higher solubility of FDCA in GVL/H2O, which allows oxidation at high concentrations using a heterogeneous catalyst that eliminates the need for a homogeneous base. Our process eliminates the use of corrosive acids, because FDCA is an effective catalyst for fructose dehydration, leading to improved economic and environmental impact of the process. Our technoeconomic model indicates that the overall process is economic and environmental impact of the process. Our technoeconomic model indicates that the overall process is economically competitive with current terephthalic acid processes. |
