Procedure
Granulated alumina (8 - 16 mesh) is heated at 1300°C. for 4 hours. Vanadium pentoxide (1.25 part) is suspended in 5 parts of water, heated to 80°C., and 3.8 parts of oxalic acid are added slowly to obtain a blue-colored vanadium oxalate solution. Sodium carbonate (0.18 part) is added to this solution, and 2.5 parts of the alumina are also placed in the said 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.
Workup
- temperatureheated to 80°C.
