Flow Technology: Towards Automated and On-Demand Synthesi s
A survey conducted at Lonza indicated that 50% of th e organic reactions would benefit from transferring from conventional batch synthesis to continuous production. Compared to batch or semibatch product ion, continuous production has the advantages of steady state operation, hi gh heat and mass transfer rates, enhanced photon flux, reproducibility, and improved safety and process reliability. However, there are a lot of probl ems associated with continuous flow synthesis, such as difficult for parall el screening, handling of solid compounds, as well as incompatibility of re agents and solvents in streamlined multistep continuous-flow synthesis.
The research in Wu’s group focus on tacking those problems by designing novel advanced flow reactors, and utilizing them in synthesis of fine chemi cals using inexpensive natural gases and hydrocarbons as feedstocks under v isible-light irradiation. Compared to stepwise batch synthesis, multistep c ontinuous flow synthesis enables the combination of multiple synthetic step s into a single and uninterrupted reactor network, thereby circumventing th e need to isolate intermediates, and enabling automated synthesis. This tal k will include the description of design of the “stop-flow micro-tubing” re actor and merging solid-phase synthesis and flow synthesis towards automate d and on-demand synthesis of value-added functionalized organic molecules.< /p>
