The invention discloses a preparation method of a supported metal ionic liquid catalyst, the obtained product and application thereof, and belongs to the technical field of catalyst preparation. The method includes: 1) polymerizing styrene, divinylbenzene or a derivative of divinylbenzene with an imidazole compound containing an unsaturated alkenyl group to obtain porous polymer microspheres; 2) polymerizing the porous polymer microspheres Use halogenated alkane, halogenated alcohol or halogenated carboxylic acid for modification to obtain grafted porous polymer microspheres; 3) Mix and heat the grafted porous polymer microspheres with zinc halide and toluene to obtain a supported metal ionic liquid catalyst . The catalyst prepared by the invention has high activity, the catalyst is easy to separate after the reaction, can be reused, and has simple preparation process and low cost. |
