Oxidation of hydrogels based of sodium alginate and MnO2 as catalyst

In this study, first a hydrogel based on sodium alginate and acrylamide was prepared by radical polymerization method then manganese oxide formed in its lattice structure nanocomposite hydrogels were obtained. the next step, Nanocomposite used as catalysts for oxidation of alcohols. To evaluate physical properties confirm hydrogels, Hydrogel swelling tests, FT-IR infrared conversion spectroscopy, TGA Thermal gravimetric, SEM Scanning electron microscopy TEM Transmission used. The amount measured using an atomic absorption spectrometer. Also, factors affecting reactions such reaction temperature, catalyst time optimized to achieve highest percentage alcohols aldehydes. Under optimal conditions, benzyl alcohol 79% Benz aldehyde at 80 °C 24 hours.
