Conventional oxidation processes for alkyl aromatics to ketones employ oxidants that tend generate harmful byproducts and cause severe equipment corrosion, ultimately creating critical environmental problems. Thus, in this study, a practical, efficient, green method was developed the synthesis of aromatic by applying bis(2-butoxyethyl) ether/O

Abstract As an important monomer material for synthesizing polycaprolactone, ε‐caprolactone (ε‐CL), is currently produced through the Baeyer–Villiger oxidation of cyclohexanone. a green and promising process to produce ε‐CL, oxidizing cyclohexanone with air in presence sacrificial agents has attracted extensive attention from academia industry. However, slow reaction kinetic weak capacity limits application this technology. Herein, we used N‐hydroxyphthalimide (NHPI) as higdhly efficient homogeneous catalyst Through investigating influence conditions such temperature, gas velocity, aldehyde‐ketone ratio, solvent ratio on conversion rate selectivity optimum condition was obtained production high 3.43 mmol/gcat/min 90%. The mechanism investigated in‐situ UV–visible spectra, electron paramagnetic resonance (EPR) starch/KI experiment, plausible mechanistic mode involving three pivotal reactions proposed. dynamic model constructed validate proposed provide good predictions actual rate. This work provides meaningful insights into NHPI‐catalyzed cyclohexanone, theoretical guidance scale‐up processes.
