将浓缩碳水化合物和原始生物质催化转化为 5-羟甲基糠醛 (HMF)，这是一种重要的增值平台化学品，对于工业应用来说非常理想，但具有挑战性。在这项工作中，焦磷酸锡氧化 (SnP ₂ O ₇ –SnO ₂ ) 催化剂被设计用于从各种浓缩碳水化合物和原始生物质中高效生产 HMF。特别是，在水和甲基异丁基酮的双相溶剂体系中，使用浓葡萄糖（36 wt%）在 SPC4 催化剂上实现了 67.8% 的高 HMF 产率。此外，SPC4催化剂具有广泛的通用性，可以将各种浓缩碳水化合物和原始生物质转化为HMF，收率令人满意（45.9-79.5%）。据我们所知，这是在如此高的底物浓度下从碳水化合物和原始生物质中获得可观的 HMF 产量的第一个例子。事实证明，该催化剂优异的催化性能应源于其平衡的路易斯和布朗斯台德酸性和超亲水性。这项工作发明了一种非常有前途的多相催化剂，可有效地将可再生木质纤维素相关化合物转化为多功能呋喃。

Efficient Production of 5-Hydroxymethylfurfural from Concentrated Carbohydrates and Raw Biomass over SnP2O7–SnO2 Catalysts

Catalytic conversion of concentrated carbohydrates and raw biomass into 5-hydroxymethylfurfural (HMF), an important and value-added platform chemical, is highly desirable for industrial applications but challenging. In this work, the tin pyrophosphate-oxide (SnP₂O₇–SnO₂) catalyst has been designed to efficiently produce HMF from various concentrated carbohydrates and raw biomass. Especially, a high HMF yield of 67.8% was implemented over the SPC4 catalyst from concentrated glucose (36 wt %) in a biphasic solvent system of water and methyl isobutyl ketone. Moreover, the SPC4 catalyst disclosed a wide range of universality for converting various concentrated carbohydrates and raw biomass to HMF with satisfactory yields (45.9–79.5%). To the best of our knowledge, this is the first example of accomplishing appreciable HMF yields from carbohydrates and raw biomass at such a high substrate concentration. It has been demonstrated that the superior catalytic performance of the catalyst should originate from its balanced Lewis and Brønsted acidity and superhydrophilicity property. This work invents a highly promising heterogeneous catalyst for efficiently valorizing renewable lignocellulose-related compounds into versatile furans.
