A study of new and more sustainable catalytic routes for the synthesis of adipic acid
The aim of my PhD research project was to investigate new and more sustainable routes, compared to those currently used, for the production of adipic acid (AA). AA is a very important chemical intermediate. The main use of AA is the production of Nylon-6,6 fibers, resins, polyesters, plasticizers....

AA is a very important chemical intermediate. The main use of AA is the production of Nylon-6,6 fibers, resins, polyesters, plasticizers. My project was divided into two parts: 1. The two-step oxidation of cyclohexene, where the latter is first oxidized into trans-1,2-cyclohexanediol (CHD) with aqueous hydrogen peroxide, and then the glycol is transformed into AA by reaction with molecular oxygen. Various catalysts were investigated in this process, both heterogeneous (alumina-supported Ru(OH)x and Au nanoparticles supported on TiO2, MgO and Mg(OH)2) and homogeneous (polyoxometalates). We also studied the mechanism of CHD oxidation with oxygen in the presence of these catalysts. 2. Baeyer-Villiger oxidation of cyclohexanone with aqueous hydrogen peroxide into ɛ-caprolactone, as a first step on the way to produce AA. Study on the mechanism of the uncatalyzed (thermal) oxidation of cyclohexanone were also carried out. Investigation on how the different heterogeneous catalysts affect the formation of the reaction products and their distribution was done.
