| titleOfInvention | Preparation method of magnetic material for removing dibenzothiophene from oil |
| abstract | The invention discloses a preparation method of a magnetic material for removing dibenzothiophene from oil. The method comprises the following steps of: preparing magnetic nanometer ferroferric oxide; preparing into a pre-assembled solution; dissolving polyvinyl pyrrolidone into a methylbenzene solution; adding azodiisobutyronitrile and a prepolymer solution to obtain a polymer; separating the obtained polymer in an external magnetic field; and putting into a mixed solution of methanol and glacial acetic acid to obtain a magnetic material. Compared with the conventional molecular engram material, a ferroferric oxide magnetic molecular engram polymer magnetic material which is synthesized by taking tetravinyl pyridine as a functional monomer, taking dibenzothiophene as a template molecule, taking ethylene glycol ethylene dimethacrylate as a crosslinking agent and taking oleic acid-coated ferroferric oxide as a load substrate with a surface molecular engram technology has the advantages of uniform particle, high mechanical strength and no need of complex steps during suction filtration and centrifugal separation, has certain adsorption volume and adsorption selectivity to dibenzothiophene in oil, and is a novel material which is low in price and is convenient and rapid for separating. |
