Procedure
Granulated alumina (8-16 mesh) is heated at 1300° C for 4 hours. Water soluble salts of the promoters 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, as needed, 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 which is ready for use after cooling.
