Heteropolyacid ionic liquid supported aminated magnetic composite of date cake structure, preparation method and application

Abstract

The invention discloses a heteropolyacid ionic liquid supported aminated magnetic composite of a date cake structure, a preparation method and an application. The composite is prepared from raw materials including a heteropolyacid ionic liquid and an aminated magnetic composite by supporting the heteropolyacid ionic liquid on an aminated nano magnetic material with an ultrasonic immersing method.The preparation steps are shown as follows: firstly, the heteropolyacid ionic liquid is prepared through a substitution reaction, the aminated magnetic composite is prepared with a solvothermal method, and the heteropolyacid ionic liquid supported aminated magnetic composite is prepared with an ultrasonic supporting method. The product obtained with the method is powdery and brown, has uniform particle size distribution and has the date cake structure and stable properties. The defect of high probability of agglomeration of the magnetic materials is overcome, and the obtained material has gooddispersity, high magnetism and high yield, and raw materials are easy to obtain; the composite has magnetism and catalytic activity and can be effectively used for a catalyst for desulfuration of petroleum samples, and the catalyst can be separately recycled.
