Product 1

HCID 3031DichlobenilYield 86.7%

Procedure

300 g of this catalyst was placed in a fluidized bed reactor, 1.5 inches in inside diameter and 100 cm high, and was heated therein at 360° C. To this catalyst layer were fed air, 2,6-dichlorotoluene containing 2% of ethyl bromide, and ammonia at rates of 75.2 N liters, 38.2 g, and 15.7 N liters per hour, respectively. The ratio of 2,6-dichlorotoluene:oxygen:ammonia was 1:3:3. 2,6-dichlorobenzonitrile was obtained in an amount of 34.7 g per hour. The quantity of unreacted 2,6-dichlorotoluene was 0.8 g. Conversion was 97.9%, yield was 86.7%, and selectivity was 88.5%.
