Abstract
We report the development of a scalable continuous Taylor vortex reactor for both UV and visible photochemistry. This builds on our recent report (Org. Process Res. Dev. 2017, 21, 1042) detailing a...
Highlights
Sustainability is a key driver for both academic and industrial chemistry research and there is a need for continual interventions to drive this agenda if we are to have a major impact on delivering sustainable chemistry.[1,2,3,4] The application of photochemistry to chemical processes is appealing in this context as photons can be considered as ‘green’ reagents
Much of the current interest in applying photochemistry for synthesis has been focussed on visible-light-induced organic reactions, in the area of photoredox catalysis,[6,7] and somewhat less attention is being paid to UV photochemistry
We describe the scale-up of a continuous Taylor vortex reactor for photochemistry and demonstrate its potential as an adaptable, high throughput UV and visible light photochemical reactor for gram to kilogram scale reactions
Summary
Sustainability is a key driver for both academic and industrial chemistry research and there is a need for continual interventions to drive this agenda if we are to have a major impact on delivering sustainable chemistry.[1,2,3,4] The application of photochemistry to chemical processes is appealing in this context as photons can be considered as ‘green’ reagents. In the smaller scale reactor we demonstrated that the amount of air drawn into the reactor increased with rotation speed (up to 4000 rpm).[39] drawing air from the laboratory is obviously beneficial from one point of view because a pressurised gas cylinder is not needed for reactions involving oxygen, this approach does not offer control over the input of gases and limits the productivity of the reactor to the amount of oxygen entrained.
