The formation of intermediates plays a key role in reactivity, selectivity and deactivation in heterogeneous catalytic processes. However, their observation and determination remain a significant challenge due to the lack of selective techniques of sufficient sensitivity to detect their low concentrations (< 10 µmol/g).[1,2] We will show how an approach combining 13C…
FlowNMR spectroscopy is a powerful technique for gaining insight into dynamic reaction systems in their native environment, allowing the observation of subtle reagent interactions, fleeting intermediates, and steady-state distribution of catalytic states. Quantification of the latter over time and correlation with the reaction progress and selectivity profile of the reaction…
Benchtop NMR spectrometers are a promising technology for process monitoring applications due to their portability, affordability and low maintenance requirements. However, the moderate magnetic fields of benchtop NMR spectrometers (1 – 2 T) limit their sensitivity and chemical shift dispersion when compared to standard laboratory NMR (> 7 T). Hyperpolarisation…
