WebMay 1, 2024 · Continuous-flow microreactor technology has been embraced by researchers in academia and industry due to its excellent transport properties and the increased safety and control over challenging chemical transformations. Despite its popularity, scaling the benefits associated with the microenvironment has proven to be a daunting challenge. WebMoreover, pump flow and pressure head can be scaled with ρ and inner diameter (d) to make the pump parameters dimensionless. However, because fluid density and inner diameter did not change for the individual pumps during static characterization, validation of scaling with these parameters was not possible and therefore not used in this study.

WebMicroreactors are generally operated in a continuous flow mode. With a reactor volume of less than a milliliter, flow chemistry allows the scale-independent synthesis from g to kg amounts in a single day. The small reactor volume facilitates the safe and easy handling of hazardous or instable materials and highly exothermic reactions.
