在线核磁共振波谱是研究复杂反应多组分混合物并获得过程洞察和理解的绝佳工具。对于工艺条件下的在线研究,流量核磁共振探头可在较宽的温度和压力范围内使用。本文汇编了复杂多组分混合物中定量过程核磁共振波谱的最重要方面,并提供了示例。在将核磁共振波谱作为在线方法引入后,对于无需在氘化溶剂中制备样品的技术样品,讨论了停留时间分布、预磁化和池设计的影响。介绍了 NMR 采集和处理参数以及数据准备方法,并介绍了最实用的数据分析策略。
Online NMR spectroscopy is an excellent tool to study complex reacting multicomponent mixtures and gain process insight and understanding. For online studies under process conditions, flow NMR probes can be used in a wide range of temperature and pressure. This paper compiles the most important aspects towards quantitative process NMR spectroscopy in complex multicomponent mixtures and provides examples. After NMR spectroscopy is introduced as an online method and for technical samples without sample preparation in deuterated solvents, influences of the residence time distribution, pre-magnetization, and cell design are discussed. NMR acquisition and processing parameters as well as data preparation methods are presented and the most practical data analysis strategies are introduced.
