The adipic acid (AA), important precursor for Nylon production, was synthesized from cyclohexanoneoxidation by two ways, microwaves irradiation and  conventional method (under reflux) using H 3 PMo 12 O 40 heteropolyacid as catalyst in the presence of hydrogen peroxide. In the order to increase the AA yield, several parameters as cyclohexanone/catalyst ratio, H 2 O 2 concentration, solvent nature (H 2 O, CH 3 CO 2 H, and CH 3 OH, CHCl 3 and CH 3 CN) and cyclohexanol addition to cyclohexanone were examined.  For both activation modes, the highest AA yields are of 26-28%. Whereas, with microwaves irradiation, the time gain is much more attractive 30 min compared to 20 h. Copyright © 2019 BCREC Group. All rights reserved
