چکیده انگلیسی
Novel heterogeneous aminated polystyrene and polyacrylate resins and vinylpyridine copolymerized with methylmethacrylate and buthylmethacrylate, were synthesized, characterized and used as supports for MTO immobilization. FTIR, UV-VIS, chemical analysis and 13C NMR indicate that tertiary amine and pyridine N-oxides can act as ligands for MTO anchoring onto polymeric resins. The amount of rhenium incorporated and the interaction between N and Re varied with the ligand type and the polymer. MTO immobilized on oxidized supports was proner to leaching than non-oxidized supports during α-pinene epoxidation with hydrogen peroxide. MTO supported on copolymers were more effective for the latter reaction than MTO supported on tertiary amines or commercial polyvinylpyridine.
