A Low-Cost and Easily Prepared Manganese Carbonate as an Effi cient Catalyst for Aerobic Oxidation of 5-Hydroxymethylfurfural to 2,5-Diformylfuran-中国期刊网

摘要 Alow-costandeasilypreparedmanganesecarbonate(MnCO3)hasbeensynthesizedforcatalyticconversionof5-hydroxymethylfurfural(5-HMF)to2,5-diformylfuran(DFF).ThepropertiesandmorphologyofthemanganesecarbonateweremeasuredbySEM,XRD,TGA,BETandXPS.Inthismethod,noharshreactionconditionswererequired,anditwasasimpleandgreenprocessfortheoxidationof5-HMFintoDFF.ToachieveanoptimumDFFyield,differentreactionconditions,includingreactiontemperature,reactiontime,catalystamount,andsolventswereinvestigated.ResultsfromtheexperimentsindicatedthatthehighestDFFyieldof86.9%wasobtainedat120°Cunderatmosphericoxygenpressureafter6h.Finally,MnCO3couldbeusedatleastfivetimeswithconsiderablestability.
