Procedure

(STEP 2): To 40 ml of water is added 0.495 gram of vanadium pentoxide, 1.09 grams of oxalic acid and 2.47 grams of formamide at room temperature with stirring to form vanadium oxalate, and this solution was then mixed with 23.0 grams of the 5.0 wt. % V2O5 on titanium dioxide anatase powder (prepared as described above in Step 1) and 1.18 grams of Sb2O3 (which were first dispersed in 20 ml of water). The resulting mixture was heated with stirring at 65° C. to evaporate the majority of the water follcwed by drying in an oven (101 kPa) at 110° C. for 16 hours. The resulting solid was then calcined in a flowing oxygen gas stream at 450° C. for 2 hours, followed by crushing and screening to form -20 +40 mesh particle size. The catalyst formed by the above impregnation procedure was determined by calculation (based on the vanadium salt, antimony salt, and the weight of the titanium dioxide particles) to contain 4.8 wt. % Sb2O3 and 6.8 wt. % V2O5 on the TiO2.
