Recognizing the challenges with previous flow-reactor designs for electrochemistry, we reasoned that to minimize the necessary reactor size a reactor design with a higher rate of mass transport would be desirable. We set out to design a new reactor pla orm where mixing was decoupled from flow rate and thereby create a reactor that has excellent mass transport and complete residence me control. Previous efforts at AbbVie had demonstrated the power of this strategy for scaling photochemical reac ons. We created a rod-based reactor system which could be u lized as a CSTR in flow (Figure ). This reactor pla orm provides several benefits over parallel plate reactors: (1) electrochemical reac ons are inherently mass transport and surface area limited, therefore the ability to u lize overhead s rring and appropriate impellor geometry would provide a high force of mixing in close proximity to the electrodes and greatly improve the mass transport, (2) using electrode rods, the distance between electrodes can be fixed between scales elimina ng a problema c scale-up factor, (3) impellor-based mixing is compa ble with biphasic reac on mixtures, (4) the use of rod-based electrodes allows for interchanging of electrode materials with rela ve ease, and (5) a CSTR with rod electrodes would provide a balanced surface area of electrode to reac on volume ra os. Previously, we disclosed this reactor design which was amendable to use in rapidly alterna ng polarity (rAP) electrochemical reac ons in batch up to 1 kg scale. Indeed, in the 3 years that we have evaluated this design for electrochemical reac ons we have seen these benefits in direct comparison to mul ple different parallel plate and microchannel reactor designs.
