Advancing Flow Chemistry Portability: A Simplified Approach to Scaling Up Flow Chemistry

We report mixing characterization of five lab-scale and eight production-scale static mixers using a modified fourth Bourne reaction. An efficient inline method relying on UV–vis spectroscopy was developed to streamline analysis of the product distribution. As a result of these studies, we have designed, 3D-printed, and characterized a stainless steel static mixer. This approach enabled the evaluation of different configurations and ensured efficient scale-up across development and commercial facilities that should allow for enhanced portability of mixing-sensitive processes.
