SALTS OF N-(4-TRIFLUOROMETHYLPHENYL)-TETRACHLOROPHTHALAMIC ACID, THEIR COMPOSITION AND THEIR USE

摘要

The present invention relates to novel salts of N-(4-trifluoromethylphenyl)tetrachlorophthalamic acid of the formula (I) in which M represents an alkali metal equivalent, alkaline earth metal equivalent, optionally substituted ammonium equivalent or heavy-metal equivalent. They are obtained from the free acid by reacting it with alkali metal hydroxide, alkaline earth metal hydroxide or optionally substituted ammonium hydroxide. The heavy-metal salts are prepared from water-soluble salts by adding the heavy-metal salts in question. The novel salts of N-(4-trifluoromethylphenyl)phthalamic acid can be used as pesticides and are distinguished by a powerful action and duration of action.
