| Zusammenfassung: | The invention concerns a process for preparing polyhalogenated para-trifluoromethylanilines by the reaction of ammonia with polyhalogenated para-trifluoromethylbenzenes at a temperature of between 180 and 270 °C. Polyhalogenated para-trifluoromethylanilines are useful as reaction intermediates for preparing compounds used as insecticides.
Opisuje sa spôsob prípravy polyhalogénovaných para-trifluórmetylanilínov reakciou amoniaku s polyhalogénovanými para-trifluórmetylbenzénmi pri teplote 180 až 270 °C. Polyhalogénované para-trifluórmetylanilíny sa používajú ako medziprodukty na prípravu zlúčenín použiteľných ako insekticídy. |
