Abstract Photobromination reaction of oxime ether (OE) to brominated (BOE) is an important process for the synthesis trifloxystrobin in fungicide industry. Herein, continuous BOE photomicroreactors was performed. Initially, investigation carried out study effects various parameters, including mixing performance, molar ratios, solvents, incident photon flux, and temperature, on photobromination process. Moreover, a kinetic model established, activation energies main side reactions were determined. The relationship between rate constant light flux illuminated. Transition states energy changes bromination analyzed using density functional theory calculation. Remarkably, 83.1% yield achieved photomicroreactor required time reduced approximately 1/10 batch reactor. This work crucial theoretical significance practical value better understanding processes parameter optimization.
