Abstract
The present disclosure discloses the preparation and application of magnetic metallic oxide cross-linked acidic polyionic liquid, belonging to the technical field of solid acid catalysis. The catalyst prepared by the present disclosure has good Lewis acid site and Brönsted acid site, and has the characteristics of high speed, high efficiency, environment friendliness and the like when catalyzing preparation of furfural from xylose. The catalyst has the advantages of easy separation, multiple cycles of recycling and the like, and is green and pollution-free. The magnetic metal oxide cross-linked acidic polyionic liquid prepared by using the present disclosure has the characteristics of high speed, high efficiency, environment friendliness and the like when catalyzing preparation of furfural from xylose, and meanwhile, the catalyst has the advantages of easy separation, multiple cycles of recycling and the like, and is green and pollution-free.
