3,4,5,6-Tetrachlorophthalic anhydride (0.30 mole) is charged into a glass reaction vessel. Concentrated ammonium hydroxide (280 ml) is incrementally added at room temperature with stirring. After the addition is completed the reaction slurry is heated with stirring for a period sufficient to evaporate most of the water present in the reaction mixture. The remaining solid is then dried in a forced air oven and is recrystallized. The recrystallized product is washed with acetone, filtered and dried to yield the desired product 3,4,5,6-tetrachlorophthalimide.
