One-pot tandem conversion of fructose into biofuel components with in-situ generated catalyst system

摘要

In this contribution,one-pot tandem conversion of fructose into biofuel components,including 5-ethoxymethylfurfural (EMF),2,5-(bis(ethoxymethyl)furan (BEMF) and ethyl levulinate (EL),was performed in an in-situ generated catalyst system through consecutive dehydration,etherification,and transfer hydrogenation.Specifically,ZrOCl2·8H2O was in-situ decomposed into HCI and ZrO(OH)2 in ethanol,which effectively catalyzed the dehydration/etherification of fructose to 5-ethoxymethylfurfural (EMF) and subsequent reductive etherification of EMF using ethanol as H-donor,respectively.EMF,BEMF and EL were detected as the main products,and total yield of detectable products of up to 65.4％ was obtained at 200 ℃ in only 2 h.
