実験手順: 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%. was kept at 390° C

実験手順: 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%. 1.5 inches in inside diameter and 100 cm high, and was heated at 360° C

実験手順: A solution of 30.0 grams (0.174 mole) of 2,6-dichlorobenzonitrile and 14.7 mL (0.174 mole) of 2-methyl-2-propen-1-ol in 200 mL of dimethyl sulfoxide was stirred, and 12.7 grams (0.191 mole) of 85% potassium hydroxide was added portionwise during a 5 minute period. During the addition, the reaction mixture temperature rose from 20° C. to about 35° C. Upon completion of the addition, the reaction mixture was stirred at ambient temperature for about 18 hours. After this time the reaction mixture was poured into 600 mL of water. The mixture was filtered to collect a solid. The solid was washed with water and dried under vacuum, yielding 33.9 grams of 2-methyl-3-(3-chloro-2-cyanophenoxy)-1-propene. The NMR spectrum was consistent with the proposed structure. During the addition rose from 20° C. to about 35° C Upon completion of the addition The mixture was filtered to collect a solid The solid was washed with water dried under vacuum

実験手順: A solution of lithium di-isopropylamide (2M in heptane, 25 ml) was added to a solution of 2,6-dichlorobenzonitrile (8.6 g) in THF while maintaining the temperature below -70° C. The mixture was stirred for 1.5 hours then poured onto solid carbon dioxide. It was stirred for 1 hour then diluted with ether. Water was added and the mixture was acidified to pH1. It was extracted with ether, washed with water, dried (MgSO4) and filtered. The filtrate was evaporated to dryness to give 3-cyano-2,4-dichlorobenzoic acid (9.4 g) as a white solid mp 230°-232° C. while maintaining the temperature below -70° C It was stirred for 1 hour It was extracted with ether washed with water dried (MgSO4) filtered The filtrate was evaporated to dryness
