The oxidation reaction of 5-hydroxymethylfurfural to the bioplastic monomer 2,5-furandicarboxylic acid over heterogenous resin-supported Pt catalysts was investigated in detail, under continuous flow, base-free conditions, and in neat water. The product was continuously obtained in 99 % yield by running the reaction at 120 °C, 303 s residence time, 1.2 mL min O flow rate, and 7.7 bar O pressure. The product was isolated with a high space-time-yield of 46.0 g L h without purifications or acid/base treatments.
详细研究了在连续流动、无碱条件下以及纯水中，5-羟甲基糠醛在非均相树脂负载的铂催化剂上氧化生成生物塑料单体2,5-呋喃二甲酸的反应。通过在120°C、303秒停留时间、1.2 mL min氧气流速和7.7 bar氧气压力下进行反应，以99%的产率连续获得产物。产物无需纯化或酸碱处理，以46.0 g L h的高空时产率分离得到。
