摘要: An economical and effective approach for the selective transformation of biomass-derived 5-hydroxymethylfurfural (HMF) into 2,5-dihydroxymethylfuran (DHMF) was developed by catalytic transfer hydrogenation over various magnetic zirconium hydroxides (MZHs). As expected, MZH with a moderate Zr/Fe molar ratio 2 displayed highest activity, resulting in 98.4% HMF conversion 89.6% DHMF yield at 150 °C 5 h presence 2-butanol that simultaneously acted as hydrogen donor reaction solvent, which ascribed to its appropriate specific surface area, pore size acid-base content. Moreover, plausible mechanism MHZ(Zr/Fe=2) also proposed, basic hydroxyl groups aid acidic metal centers were considered be responsible pivotal hydride via six-membered ring structure.
