The synthesis of magnetic nanoparticle supported schiff bases metal complexes and the anaysis of their catalytic activity

In this study, novel magnetically recyclable Mn nanocatalysts have been synthesized with magnetic nanoparticles and various Schiff bases. Nanoparticles of magnetic Fe3O4 were first synthesized. Then a solid support was synthesized with dopamine hydrochloride and Schiff base ligands were synthesized. Finally, Mn metal complexes were synthesized using Mn(II)acetate. These catalysts were characterized by FT-IR (fourier transformer infrared spectroscopy) and X-Ray diffraction. The prepared magnetic nanocatalysts were tested as catalysts in epoxidation reactions. The prepared novel magnetic nanocatalysts showed high activity and selectivity as in a homogeneous system. It was also well dispersed in solution. The catalyst was easily separable.
