Abstract
Metalloporphyrins of Fe-III and Cu-II were prepared inside the large pores of the zeolite NaY by a process of sequential introduction of components fo llowed by assembly inside the void space of the zeolite. The appropriate pr ocess chosen for the porphyrin synthesis was using the propionic acid solve nt for reaction between pyrrole and benzaldehyde and this solvent was not d estructive for zeolite. The powder X-ray diffraction data confirmed that th e crystallinity of the zeolite was maintained. The resulting materials were purified by Soxhlet extractor. The zeolite-included metalloporphyrins were identified for studies using UV-Vis, FTIR and EPR Spectroscopy, CA (chemic al analysis), AAS (atomic absorption spectroscopy), TG/DSC, XRD, SEM and C- 13-NMR techniques. The catalytic activity of these products was examined an d the catalyst showed to be a promising catalytic system to aliphatic hydro carbon oxidation reactions. (C) 2000 Elsevier Science B.V.
