A simple and effective water extraction method is presented for the purification 5-hydroxylmethylfurfural (HMF) obtained from a biomass dehydration system. Up to 99% of the HMF can be recovered and the HMF in aqueous solution is directly converted to 2,5-furandicarboxylic acid (FDCA) as the sole product. This purification technique allows an integrated process to produce FDCA from fructose via HMF prepared in an isopropanol monophasic system, with an overall FDCA yield of 83% obtained. From Jerusalem raw artichoke biomass to FDCA via HMF prepared in a water/MIBK (methyl isobutyl ketone) biphasic system, an overall FDCA yield of 55% is obtained.
提出了一种简单有效的水萃取方法，用于从生物质脱水系统中获得的5-羟甲基糠醛（HMF）的纯化。高达99%的HMF可被回收，并且水溶液中的HMF可直接转化为唯一产物2,5-呋喃二甲酸（FDCA）。这种纯化技术允许通过在异丙醇单相系统中制备的HMF从果糖生产FDCA的集成工艺，获得的FDCA总产率为83%。从菊芋生物质通过在水/甲基异丁基酮（MIBK）双相系统中制备的HMF到FDCA，获得的FDCA总产率为55%。
