Continuous Flow Chemistry

Using Online PAT Analyses

Panoramica del programma

  • Facilitate the discovery and rapid optimization of continuous flow chemistry processes
  • Early implementation of flow chemistry in drug discovery and development
  • Why continuous flow chemistry is inherently safe chemistry

Continuous manufacturing technology, or flow chemistry, provides a potentially highly controlled and data-rich environment for the development of robust manufacturing routes to complex molecules. Further, the technology can be leveraged to deliver low cost manufacturing plants and significantly simplified tech transfer. Realizing the benefits from continuous manufacturing technologies requires chemical, analytical and engineering expertise. The development of appropriate scale-down models for continuous manufacturing further complicates the efficient development of continuous manufacturing processes. The utility of the application of various process analytical technologies to the lab scale design and developing continuous processes for the pharmaceutical and fine chemical industries will be discussed. Case studies highlighting solutions and challenges of developing flow chemistry processes will be presented.

Continuous flow chemistry can be used for potentially hazardous reactions, including:

  • Hydrogenation - flammable, combustible, detonation risk
  • Oxidation - exothermic, highly reactive, explosion hazard
  • Halogenation - corrosive, toxic
  • Nitrogen Compounds - exothermic, explosive, toxic
  • Reactive Low MW Carbon Compounds - toxic, CO, cyanides, phosgene
