Reaction Steps
Granulated alumina (8-16 mesh) is heated at 1300° C. for 4 hours. Potassium niobate (4K2O.3Nb2O5.16H2O) and vanadium pentoxide are suspended in 5 parts of water, heated to 80° C., and oxalic acid is added slowly to obtain a blue-colored vanadium oxalate solution. Sodium carbonate is added and the alumina is also placed in the solution. The mixture is dried over a water bath with agitation. While air is pumped in, it is indurated in a furnace at 400° C. for 16 hours to obtain the catalyst ready for use after cooling.
