Selection and reaction conditions optimization of biphasic systems for conversion of xylose into furfural
摘要
Abstract
The dissolution behavior of furfural in various organic solvent/water biphasic systems was systematically investigated.The reaction conditions for conversion of xylose into furfural were optimized using FePO4 as the catalyst and D-xylose as the substrate.The 2-methyltetrahydrofuran(2-MTHF)was regarded as the optimal organic phase through comparing the dissolution capacities to furfural and partition coefficients of six organic solvent/water systems.Under the optimized conditions with a reaction temperature of 190℃,reaction time of 3 h,organic-to-aqueous phase volume ratio of 1∶2,and NaCl dosage of 33.3 g/L,the yield of furfural was achieved at 95.19％,which was enhanced by 12.84％ compared to the system without NaCl.The results of molecular dynamics simulations revealed that Na+and Cl-significantly enhanced the reaction efficiency by altering the solvation environment of xylose,promoting its interfacial accumulation,and facilitating the migration of furfural toward the organic phase.关键词
