摘要
前盖具有液相加氢反应器，在工业相关条件下采用衰减全反射红外（ATR-IR），拉曼和荧光光谱。具体来说，它强调了使用在线ATR-IR光谱和偏最小二乘回归来确定从获得的光谱中获得的两种生物衍生内酯的浓度。B. M. Weckhuysen及其同事的研究文章（DOI: 10.1002/cmtd）。202500054)，澄清了反应器设计，并确定了非浓度变化引起的光谱变化，揭示了在反应条件下进行光谱分析的挑战。
Front Cover: Process Monitoring of Lactone Ring Formation and Opening by Operando Attenuated Total Reflectance Infrared Spectroscopy (Chem. Methods 10/2025)
The Front Cover features a liquid-phase hydrogenation reactor, employing attenuated total reflectance-infrared (ATR-IR), Raman, and fluorescence spectroscopy under industrially relevant conditions. Specifically, it highlights the use of inline ATR-IR spectroscopy and partial least-squares regression to determine the concentrations of two bio-derived lactones from the acquired spectra. In the Research Article by B. M. Weckhuysen and co-workers (DOI: 10.1002/cmtd.202500054), the reactor design is clarified, and changes in the spectra not induced by concentration changes are pinpointed, shedding light on the challenges associated with performing spectroscopy under reaction conditions.
