Abstract
Gas–liquid oxidation processes, despite their wide application in the chemical industry,
still pose considerable safety concerns. Microchemical technology has received high
recognition for its intrinsic safety performance and process-intensification capability
in hazardous reactions. This Short Review offers a comprehensive summary on how microchemical
technology can be employed to achieve gas–liquid oxidation processes for continuous
synthesis of chemicals in a safe, efficient, and controlled manner. Herein, we discuss
the key aspects of gas–liquid dispersion and hydrodynamics, as well as mass transfer
characteristics on microscale, and present representative gas–liquid oxidation cases
in microflow reactors. Finally, the current challenges in industrial applications
and potential academic research directions are presented.
