The application of N-doped carbon as a basic, heterogeneous catalyst in a continuous-flow process is described for the first time. The Knoevenagel condensation reaction was chosen to demonstrate the potential of N-doped carbon toward the development of sustainable, scalable processes that require a basic catalyst. The practical potential and performance advantages of the flow approach compared to a conventional batch system were envisioned. Under flow conditions, products were continuously synthesized for 200 h with high conversions up to 95%. The presented metal-free flow system successfully operated under mild reaction conditions, with temperatures ranging from 25 to 70 °C and ethanol as a solvent, which embody key principles of green chemistry.

N掺杂碳作为固体碱催化剂，用于连续流动的Knoevenagel缩合反应

首次描述了将N掺杂的碳作为碱性，非均相催化剂在连续流工艺中的应用。选择Knoevenagel缩合反应是为了证明N掺杂碳在开发需要碱性催化剂的可持续，可扩展工艺方面的潜力。设想了与常规批处理系统相比，流动方法的实际潜力和性能优势。在流动条件下，产物连续合成200小时，转化率高达95％。提出的无金属流动系统在温和的反应条件下成功运行，温度范围为25至70°C，乙醇为溶剂，体现了绿色化学的关键原理。
