Use | This product is used in the synthesis of 2, 4-difluoro-3, 5-dichloroaniline, an intermediate of fluorophenylurea. |
production method | the preparation method is to fluorinate 2,3,4, 5-tetrachloronitrobenzene with potassium fluoride, 2, 4-difluoro-3, 5-dichloronitrobenzene was obtained. Add a certain amount of 2,3,4, 5-tetrachloronitrobenzene, dimethyl sulfoxide and anhydrous potassium fluoride in the reactor, react at 150 ℃ for 10h, trace the reaction by thin layer analysis, after completion of the reaction, distillation was performed under reduced pressure to obtain 2, 4-difluoro-3, 5-dichloronitrobenzene. |
