We report a process for converting fructose, at a high concentration (15 weight %), to 2,5-furandicarboxylic acid (FDCA), a monomer used in the production of polyethylene furanoate, a renewable plastic. In our process, fructose is dehydrated to hydroxymethylfurfural (HMF) at high yields (70%) using a γ-valerolactone (GVL)/HO solvent system. HMF is subsequently oxidized to FDCA over a Pt/C catalyst with 93% yield. The advantage of our system is the higher solubility of FDCA in GVL/HO, which allows oxidation at high concentrations using a heterogeneous catalyst that eliminates the need for a homogeneous base. In addition, FDCA can be separated from the GVL/HO solvent system by crystallization to obtain >99% pure FDCA. 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 techno-economic model indicates that the overall process is economically competitive with current terephthalic acid processes.
我们报道了一种将高浓度（15重量%）果糖转化为2,5-呋喃二甲酸（FDCA）的方法，FDCA是用于生产聚呋喃二甲酸乙二酯（一种可再生塑料）的单体。在我们的方法中，使用γ-戊内酯（GVL）/HO溶剂体系，果糖以高产率（70%）脱水生成羟甲基糠醛（HMF）。随后，HMF在Pt/C催化剂上被氧化为FDCA，产率为93%。我们体系的优势在于FDCA在GVL/HO中的溶解度更高，这使得能够使用非均相催化剂在高浓度下进行氧化，从而无需均相碱。此外，FDCA可通过结晶从GVL/HO溶剂体系中分离出来，以获得纯度>99%的FDCA。我们的方法无需使用腐蚀性酸，因为FDCA是果糖脱水的有效催化剂，这使得该方法在经济和环境方面的影响得到改善。我们的技术经济模型表明，整个过程在经济上与目前的对苯二甲酸工艺具有竞争力。
