Enantioselective Organocatalysis in Microreactors: Continuous Flow Synthesis of a (S)-Pregabalin Precursor and (S)-Warfarin

Continuous flow processes have recently emerged as a powerful technology for performing chemical transformations since they ensure some advantages over traditional batch procedures. In this work, the use of commercially available and affordable PEEK (Polyetheretherketone) and PTFE (Polytetrafluoroethylene) HPLC (High Performance Liquid Chromatography) tubing as microreactors was exploited to pe...

Flow Visualization Around a Non - Circular Tube

The flow behavior around a cam shaped tube in cross flow has been investigated experimentally using flow visualization and pressure distribution measurement. The range of attack angle and Reynolds number based on an equivalent circular diameter are within 0 ≤ α ≤ 360˚ and 2 x 104 < Reeq < 3.4 x 104, respectively. The pressure drag features are clarified in relation to the flow behavior around t...

Continuous flow processing from microreactors to mesoscale: the Bohlmann-Rahtz cyclodehydration reaction.

The cyclodehydration of a number of Bohlmann-Rahtz aminodienones exemplifies the use of continuous flow processing to transfer operations from commercial microreactors and microwave batch reactors to mesoscale production using different technology platforms, including a microwave flow reactor.

Flash Chemistry: Fast Chemical Synthesis in Flow Microreactors

The length of time that the solution remains inside the reactor channels—the residence time—can be greatly reduced by adjusting the length of the channels in flow microreactors. This feature is extremely useful in controlling reactive species. Unstable short-lived reactive species can be generated and transferred to another location to be used in the next reaction before they decompose. Therefo...
