3,5-dichloro-4-(1,1,2,2-tetrafluoroethoxy)benzeneamine - Reference Information
| Uses | 3, 5-dichloro-4-(1,1,2, 2-tetrafluoroethoxy) aniline is an intermediate of the insecticide fluorolluron. |
| Production method | The preparation method is to fluorinate 2, 6-dichloro-4-aminophenol with tetrafluoroethylene in the presence of a catalyst to obtain 3, 5-dichloro-4-(1,1,2, 2-tetrafluoroethoxy) aniline. 2, 6-dichloro-4-aminophenol is mixed with DMF and KOH in proportion to form a solution, leaching from the addition tower, passing tetrafluoroethylene from under the tower for fluorination reaction, and then dissolving and recovering DMF, Refined with toluene to obtain the required product. |
