Flow photo chemistry: A meso-scale reactor for industrial applications
Developing flow photochemistry, especially at meso-scale where significant productivity is required, remains challenging. There is a need for innovative equipments generating highly controlled flow under light irradiation. In this work, a commercial solution, developed by Corning, is presented and studied by LGC and MEPI on an intramolecular (2+2) photo-cycloaddition. Detailed experimental and modelling analysis has been performed to emphasize the flow reactor behaviour and performances, and demonstrate its capability in producing up to 30g.h-1 of the desired molecule. Through this simple model reaction, the G1 photo-reactor is shown to be an efficient meso-scale reactor for industrial photo-applications development and production.
Since the last decade, Process Intensification opens up interesting perspectives for the Fine Chemical and Pharmaceutical industries. A wide range of chemistries has been investigated through the use of flow reactors showing the advantages and the improvements related to such technologies, with regards to quality, safety, competitiveness and eco-impact. In this way, various equipments based on the tubular or the heat-exchanger concepts have been developed. All these equipments benefit from miniaturization techniques and micro (or milli)-fluidics t ... ...
