A Green Method for Synthesizing Nickel Nanoparticles Supported by Magnetized Pectin: Applied as a Catalyst for Aldehyde Synthesis as a Precursor in Xanthan Synthesis

چکیده مقاله

In this paper, the properties of a catalyst that composed of magnetic nanoparticles and Pectin biopolymer that is widely found in nature (Fe3O4@Pectin) to support nickel (II) acetate are discussed, and this catalyst was then used in response to the synthesis of the precursor required for xanthene synthesis. The heterogeneous catalyst was characterized by techniques such as FT-IR spectroscopy, FE-SEM, TEM, XRD spectroscopy, EDX spectroscopy, VSM, and ICP spectroscopy. Thermal gravimetric analysis (TGA) was also used to determine the thermal stability of the material techniques. Then the catalyst was explored in the oxidation reaction of alcohols that has high efficiency and selectivity and the synthesized aldehydes were used as precursors for the synthesis of xanthans. Xanthans are important compounds found in a variety of biological components and drugs. The most important advantages of this method are easy to work up procedure, perform the reaction in solvent-free conditions, and the catalyst can be separated by an external magnet and used several times without reducing the activity.
