摘要:The present invention provides a process for the synthesis of Furandicarboxylic acid (FDCA) comprising heating a mixture of fructose, aqueous NaCl or KCl, solvent, methyl isobutyl ketone (MIBK) and a catalyst at a temperature in the range of 150 to 200° C. in a sealed vessel for a time period in the range of 2 to 5 hours to yield crude 5-(hydroxymethyl)furfural (5-HMF). The crude 5-HMF further reacts with a biocatalyst at a temperature in a range of 20 to 50° C. for a period at a range of 24 to 96 hours to yield FDCA, wherein the conversion of 5-HMF to FDCA is in the range of 90 to 100%.
