Immobilized tungstate on magnetic poly(2-ammonium ethyl acrylamide): A high loaded heterogeneous catalyst for selective oxidation of sulfides using H2O2

A heterogeneous tungstate-based catalyst has been prepared for selective oxidation of sulfides tosulfoxides in the presence of 30% H2O2. The catalyst was prepared via immobilization of high amounts ofWO42 onto the cross-linked poly(ammonium ethyl acrylamide) coated magnetic nanoparticles (MNP). FT-IR, TEM, TGA, VSM, XRD, EDX, and CHN analysis were used for characterization of catalyst. Variety ofsulfides successfully converted to the related sulfoxides using 1 mol% of catalyst at room temperature inhigh yields. The catalyst was easily recovered and reused up to 6 times without loss of activity.
