Abstract: Multiphase gas-liquid reactions are crucial in drug manufacturing in the pharmaceutical industry. They are predominantly performed in industrial-scale batch reactors, which faces heat and mass transport challenges. Therefore, more efficient, and 'greener' continuous flow reactors, that conventionally employs permanent immobilization of heterogeneous catalysts on/in solid supports are preferred to be used to catalyze the reactions. But they face challenges in terms of catalyst recovery and replacement. This dissertation introduces flow reactors that can transiently immobilize liquid-phase catalysts via capillarity - 'Capillary Force Trap Reactors (CFTRs)', in three different configurations. The first focuses in establishing a proof-of-concept by employing isolated aqueous nanoparticle catalysts in dimpled-shaped traps. The second demonstrates a continuous flow version of the CFTR where the catalysts are constantly pumped into the reactor. The last employs the concept of capillary liquid entrapment in packed bed reactors, using inert beads with liquid catalysts trapped in interstitial spaces between beads.
