摘要: A novel vanadium oxide catalyst supported on active carbon was prepared by an incipient wetness impregnation method, and the precursor was obtained from oxalic acid aqueous solutions of NH4VO3.The catalyst was applied liquid phase oxidation of glyoxal to glyoxylic acid.It was found that V2O5/C catalyst exhibited obvious activity for glyoxal oxidation.Glyoxylic acid could be obtained without pH regulation during the reaction.By using this catalyst, the conversion of glyoxal and the yield of glyoxalic acid were 29.2% and 13.6%, respectively at 313 K and oxygen flow 0.1 L/min after reaction for 10h.
