5-hydroxymethylfurfural (HMF) was produced from glucose using WO3-MoO3mixed metal oxides as the catalyst in a biphasic system (H2O-NaCl/THF), comprised of reactive aqueous phase saturated with NaCl, and containing AlCl3.6H2O, combined with an organic extracting phase consisting of tetrahydrofuran (THF). The influences of different catalysts, initial concentrations of glucose and reaction time on preparation of HMF were investigated. As a result, A HMF yield of 61% could be obtained at 170 °C in 40 min. Recycle of the aqueous phase and WO3-MoO3demonstrated constant activity after 4 cycles of use. |
