Step 1: Preparation of phthalimide. Mix phthalic anhyde (10 g) and urea (2 g) in a 250 ml RBF. A process for the continuous preparation of anthranilic acid by a two-stage reaction of an alkali metal phthalamate and/or an alkali metal phthalimidate Preparation of anthranilic acid amides by mixing phthalamic acid with lye, catalyst and hypohalite, the mixture then being left to stand for 1 to 1000 Abstract. Phthalimide formation of Phthalic anhydride with various amines using microwave or without a method with the difference.
