A one-pot set-up for real-time reaction monitoring by FTIR spectroscopy

• This paper presents a method for monitoring solution reactions in real time using Fourier transform infrared (FTIR) spectroscopy. Compared to batch measurements or flow-through systems, where the reaction and spectroscopic measurements are spatially and temporarily separated, this method enables continuous FTIR spectroscopic measurements of reactions without delay and directly in the reaction vessel. The strengths are demonstrated, and the limitations of the method are highlighted using the reaction of a lignin model compound and a sulphite salt. The method is capable of identifying both kinetic and thermodynamic properties (e.g. reaction speed, intermediate species), allowing rapid and cost-effective optimisation of reaction parameters. While specificity can be limited, the non-destructive nature of the method facilitates direct coupling to other techniques to help resolve potential ambiguities. The method is of general interest in wet chemistry applications and in several areas of the lignocellulosic biomass field in particular, as it can provide new insights into natural and industrial reactions and processes.
