Embodiment 1
[0021] 400 ml of distilled water was introduced into a 500 cc glass reactor and stirred while heating to 75°C. 300 g of citric acid was dissolved in the resulting solution. 100 g of ammonium molybdate, 19.7 g of iron nitrate, and 54.95 g of cobalt nitrate were sequentially added to dissolve them completely. In the resulting solution, a nitric acid solution of 34.35 g of bismuth nitrate and 0.286 g of potassium nitrate was added, and dried in a rotary vacuum drier. The dried catalyst cake was recovered and ground to a size of 40 mesh to obtain a catalyst powder. The combined catalyst powders were calcined at 450° C. for 5 hours in a sintering furnace to obtain a catalyst. Calcination is carried out in the presence of air.
[0022] The composition of the catalyst is Mo 12 Bi 1.5 co 4.4 Fe 2 K 0.06 .
Embodiment 2
[0027] 400 ml of distilled water was introduced into a 500 cc glass reactor and stirred while heating to 75°C. 400 g of maleic acid was dissolved in the resulting solution. 100 g of ammonium molybdate, 39.4 g of iron nitrate, and 60.44 g of cobalt nitrate were sequentially added to dissolve them completely. In the resulting solution, a nitric acid solution of 34.35 g of bismuth nitrate and 0.286 g of potassium nitrate was added, and dried in a rotary vacuum drier. The drying and calcination steps are the same as in Example 1.
[0028] The composition of the catalyst is Mo 12 Bi 1.5 co 4.4 Fe 2 K 0.06 .
Embodiment 3
[0030] The catalyst was prepared in the same manner as in Example 1, except that 300 g of oxalic acid was used.
[0031] The composition of the catalyst is Mo 12 Bi 1.5 co 4.4 Fe 2 K 0.06 .
