Construction of a Case Library for Green Chemistry-Taking the Preparation of Biobased p-xylene from Furan Compounds as an Example
Strengthen the cooperation between universities and companies in industry,academia,and research,update and improve teaching content in a timely manner based on the current situation of green chemistry course construction,and build knowledge point cases for biomass resource development and utilization.The direct synthesis of bio-based para xylene from renewable resources has important scientific significance and potential application value in promoting the efficient utilization of renewable biomass resources and the development of high-value bio-based chemicals.The aim of this work is to improve the yield and selectivity of p-xylene(produced by furan)using zeolite modified with La2O3 and CeO2 with different loading capacities and Si/Al ratios.On modified zeolites,the yield of para xylene generated by directional transformation of furan compounds can be increased.The selectivity of PX has significantly improved,mainly due to the effective removal of non-selective external acidic sites and the reduction of modified zeolite pore size.
