5-Hydroxymethylfurfural [HMF] is an important intermediate compound for fine chemicals. It is often obtained via hydrothermal treatment of biomass-derived carbohydrates, such as fructose, glucose and sucrose. This study investigates the formation of carbonaceous spheres from HMF created by dehydration of fructose under hydrothermal conditions. The carbonaceous spheres, ranging between 0.4 and 10 μm in diameter, have granulated morphologies both on the surface and in the interior. The residual solution is found to contain a massive number of primary nanoparticles. The chemical structure of the carbonaceous spheres was characterised by means of FTIR and NMR spectroscopies. Based on these observations, a mechanism involving the formation and aggregation of the nanoparticles is proposed. This mechanism differs considerably from the conventional understanding in the open literature.
5-羟甲基糠醛[HMF]是精细化学品的一种重要中间化合物。它通常通过对生物质衍生的碳水化合物（如果糖、葡萄糖和蔗糖）进行水热处理获得。本研究调查了在水热条件下由果糖脱水生成的HMF形成碳质球的过程。这些碳质球直径在0.4至10μm之间，其表面和内部均具有颗粒状形态。发现残余溶液中含有大量初级纳米颗粒。通过傅里叶变换红外光谱（FTIR）和核磁共振光谱（NMR）对碳质球的化学结构进行了表征。基于这些观察结果，提出了一种涉及纳米颗粒形成和聚集的机制。该机制与公开文献中的传统认识有很大不同。
