Development of Micro to Milli-Scale Multiphase Reactors with and Without Solids for Integration Into Mini-Monoplants
… is typically performed in flexible batch reactors, where larger scale vessels inherit both reduced heat transfer through a loss in surface-to-volume ratio, and decreased mass transfer through solvent dilution. As a result, pharmaceutical production processes are often run at suboptimal …
