Procedure: In a conventional acidic hydrolysis, the 4-chlorophthaloyl chloride or 4-chlorophthalonitrile of Examples 7 or 8 is hydrolyzed to 4-chlorophthalic acid which, upon dehydration at over 180°-200° C., will afford a high yield of 4-chlorophthalic anhydride.

Procedure: To a 1-l three-necked flask, equipped with a mechanical stirrer, a condenser with a gas outlet and an equa-pressured addition funnel, is charged 166.5 g (1 mole) of 4-chlorotetrahydrophthalonitrile and 75 g of chlorobenzene. The mixture is heated to 100°-110° C. with stirring. Bromine, 320 g (2 moles), is added dropwise into the mixture in a sub-surface manner. The red color of bromine dissipates quickly and a gas evolution starts. After about 240 g of bromine is added, the pot temperature is heated to 135° C. The addition of bromine continues until completion. The pot temperature is then raised to 165°-170° C. for 2-4 hours. During this period an additional amount of bromine, such as about 10 to 15 g, may be added to complete the conversion of 4-chlorotetrahydro-phthalonitrile. A good yield of 4-chlorophthalonitrile can be obtained by distilling out the chlorobenzene. To a 1-l three-necked flask, equipped with a mechanical stirrer, a condenser with a gas outlet and an equa-pressured addition funnel The mixture is heated to 100°-110° C. The pot temperature is then raised to 165°-170° C. for 2-4 hours such as about 10 to 15 g, may be added
