H3PMo12O40@MOF as a New Catalytic System for Cycloxexanone Oxidation to Adipic Acid

Tassadit Mazari, Dahbia Amitouche, Sihem Mouanni, Leila DERMECHE et autres

Keggin-type phosphomolibdic acid (H3PMo12O40, PMo12) encapsulated in the mesocages of chromium-based terephthalate metal–organic framework (MIL-101), was established to be an active and new green catalyst for the adipic acid (AA) synthesis via cyclohexanone (-One) oxidation in free solvent conditions and hydrogen peroxide …

Transition metal-substituted Keggin-type polyoxometalates as catalysts for adipic acid production

Sihem Mouanni, Dahbia Amitouche, Tassadit Mazari, C. Rabia

The adipic acid (AA) production was carried out in two stages: oxidation of cyclohexanone (-one) by Keggin-type polyoxometalate (POM), followed by oxidation of this latter by hydrogen peroxide. The process lasts 20 h and the temperature is maintained at 90 °C. AA …

Cyclohexanone Oxidation over H3PMo12O40 Heteropolyacid via Two Activation Modes Microwave Irradiation and Conventional Method

Yasmina Idrissou, Sihem Mouanni, Dahbia Amitouche, Tassadit Mazari et autres

The adipic acid (AA), important precursor for Nylon production, was synthesized from cyclohexanoneoxidation by two ways, microwaves irradiation and conventional method (under reflux) using H3PMo12O40 heteropolyacid as catalyst in the presence of hydrogen peroxide. In the order to increase the AA yield, …
