Preparation of anthranilic acid amides |
摘要 |
Anthranilic acid amides are prepared by mixing phthalamic acid with a caustic alkali solution, a catalyst and a hypohalite, allowing the mixture to stand for from 1 to 1,000 seconds, then introducing the amine and thereafter addig acid until the pH of the mixture is from 6 to 8. The anthranilic acid amides obtainable by the process of the invention are valuable starting materials for the preparation of dyes, scents and pesticides.
