Flow vs. Batch

Chemistry performed in a flow reactor can be used as a rapid screening tool to improve traditional batch chemistry.

Reactions performed in round-bottomed flasks (for example) are difficult and time-consuming to optimise. AFRICA offers a new  way to optimise, by allowing many different reactions to be tested rapidly with very little reagent consumption.

We call the approach BFB – Batch to Flow to Batch optimisation

But do batch and flow conditions relate to each other? Our validation work yields the following conclusions:

  • Batch reaction time is comparable to flow reaction time under the same conditions
  • Flow reaction time can be reduced very easily by pressurising the flow stream with the Pressurisation Module
  • A reaction can be optimised in flow mode, and the results transferred back to batch.

Some caveats must be noted, however:

  • A batch reaction is generally subject to more variability from run to run than with flow.
  • Some batch reactions cannot be run in flow (eg reactions forming solid products)
  • Some flow reactions cannot be performed in batch (eg using reactive intermediates)

Batch to Flow to Batch (BFB) is a rapid and productive tool for Method development and Reaction Optimisation
