This work tries to close the gap between continuous synthesis, measurement, calibration, and analysis on R&D scale. By introducing new calibration methods, the full potential of inline ATR‐FTIR spectroscopy in continuous reactor setups is unraveled. A fast, fully automated calibration of the reaction mixtures is carried out at process conditions. The use of different compositions underlines the robustness of this calibration method, which was used for the determination of kinetic parameters. The conversion‐based calibration significantly increased the precision of the analysis. In difference, the new method only requires the preparation of two calibration mixtures. By that, this method can also be applied to large‐scale processes and allows the use of a single measurement setup from R&D to industrial scale.

加热–在连续酯化的工艺条件下校准红外光谱

这项工作试图缩小研发规模上的连续合成，测量，校准和分析之间的差距。通过引入新的校准方法，可以揭示连续反应堆装置中在线ATR-FTIR光谱的全部潜力。在过程条件下进行反应混合物的快速，全自动校准。不同成分的使用强调了该校准方法的稳健性，该方法用于确定动力学参数。基于转换的校准显着提高了分析的准确性。不同的是，新方法只需要准备两种校准混合物。这样，该方法还可以应用于大规模过程，并允许使用从研发到工业规模的单一测量设置。
