Reaction Conditions

Reaction Steps

Anthranilic acid (14.0 parts) and 11.7 parts of sodium carbonate were dissolved in 250 parts of water, and a solution obtained by dissolving 10.1 parts of terephthalic acid dichloride in 60 parts of acetone was added dropwise to the above solution with stirring at 20 to 30° C. Reaction was carried out at room temperature for 2 hours after the dropwise addition and further under acetone reflux for one hour. Then, concentrated hydrochloric acid was added to make the reaction system acidic, and the precipitate was filtered and dried to obtain 19.1 parts of terephthaloyl-bisanthranilic acid.
