Reaction Steps

270 g of this catalyst was charged into the same fluidized bed reactor as used in Example 1. The catalyst layer was kept at 390° C. To the catalyst layer were fed air, 2,6-dichlorotoluene containing 2% of ethyl bromide, and ammonia at rates of 71.6 N liters, 25.0 g, and 17 N liters per hour, respectively. The ratio of 2,6-dichlorotoluene:oxygen:ammonia was 1.0:4.2:5.0. 2,6-dichlorobenzonitrile was obtained in an amount of 21.5 g per hour. The quantity of unreacted 2,6-dichlorotoluene was 1.6 g. Conversion was 94.5%, yield was 82.3%, and selectivity was 87.1%.
