Direct oxidation of cyclohexene with inert polymeric membrane reactor

In this work, the use of PVDF flat membranes as contactors for direct solvent-free biphasic oxidation of cyclohexene to adipic acid has been reported. The oxidation has been carried out using 30% H2O2 and ammonium molybdate ((NH4)6Mo7O24) in the presence of succinic acid. The effect of different membranes as interfaces between the organic phase, containing cyclohexene, and the aqueous phase, with the oxidant and catalyst, has been studied and related to conversion and selectivity.
