摘要

本研究的重点是在温和的操作条件下，采用 10 % Pd/C 连续流催化工艺，串联多步骤将 5-hydroxymethylfurfural (HMF) 转化为有价值的呋喃衍生物。结果表明，在温和的条件下和较短的反应时间内，5-羟甲基糠醛可选择性地转化为糠醇，收率超过 99%，随后糠醇可通过氧化偶联转化为有价值的产品（亚胺）。与间歇式方法相比，这种连续流方法具有多项优势，包括能够通过精确控制温度、压力和流速等参数实现高产率，从而促进工艺优化和可扩展性。

Continuous Flow valorization of furanics: From decarbonylation of 5-Hydroxymethyl-furfural to furfuryl alcohol conversion into valuable oxidative coupling products

This study focuses on the tandem multi-step valorization of 5-hydroxymethylfurfural (HMF) to valuable furanic derivatives using a catalytic process with 10 % Pd/C in continuous flow under mild operating conditions. The results demonstrate the selective conversion of 5-HMF to furfuryl alcohol with yields exceeding 99 % under mild conditions and short times of reaction, subsequently followed by the conversion of furfuryl alcohol to valuable products (imines) via oxidative coupling. This continuous flow approach offers several advantages over batch methods, including the ability to achieve high yields with precise control of parameters such as temperature, pressure, and flow rate, thereby facilitating process optimization and scalability.

期刊介绍： Catalysis Today focuses on the rapid publication of original invited papers devoted to currently important topics in catalysis and related subjects. The journal only publishes special issues (Proposing a Catalysis Today Special Issue), each of which is supervised by Guest Editors who recruit individual papers and oversee the peer review process. Catalysis Today offers researchers in the field of catalysis in-depth overviews of topical issues. Both fundamental and applied aspects of catalysis are covered. Subjects such as catalysis of immobilized organometallic and biocatalytic systems are welcome. Subjects related to catalysis such as experimental techniques, adsorption, process technology, synthesis, in situ characterization, computational, theoretical modeling, imaging and others are included if there is a clear relationship to catalysis.
