Enhancing mass transport to accelerate photoreactions and enable scale-up

15 December 2023, Version 1
Working Paper
This content is a preprint and has not undergone peer review at the time of posting.

Abstract

The importance of mixing in photoreactors along the direction of light propagation for competitive photochemical reactions is experimentally demonstrated in the MISCOP mini-plant photoreactor. The installation of customized static mixers improved the photonic efficiency of the photochemical ring-opening isomerization of 1,3,3-trimethylindolino-6'-nitrobenzopyrylospirane by a factor of 2.4, which could be related to the improved mass transport. This knowledge enables future scaling of photoreactions in multi-lamp reactors.
