Research Progress of Preparation of p-Xylene from Biomass-derived Platform Molecules
The research status of preparing p-xylene(pX)from biomass-derived platform molecules was reviewed,focusing on the pathways and catalysts for the synthesis of pX by the reaction of 2,5-dimethylfuran(DMF)with ethylene.The molecular sieves,silica,heteropolyacids,phosphates and other solid-acid-catalyzed systems were described in detail.And the studies briefly introduced the reactions of 2,5-dimethylfuran with ethanol and acrylic acid as well as the synthesis of pX from other biomass platform molecules including 2-methylfuran,2,5-hexanedione and isoprene.The current status of the research on each route was summarized,and the future research ideas were proposed.
