Use | Intermediate 2,3,4, 5-tetrachloronitrobenzene for the synthesis of the insecticide fluorophenylurea, 4-difluoro-3, 5-dichloronitrobenzene. |
production method | the preparation method is prepared by chlorination of 2,4, 5-trichloronitrobenzene. Add a certain amount of 2,4, 5-trichloronitrobenzene and chlorosulfonic acid in the reactor, enter the chlorine gas, the temperature is controlled at (60±10)℃, the reaction time is about 10H, the reaction was followed by thin layer analysis. After completion of the reaction, it is poured into a large amount of ice water, allowed to stand, filtered, recrystallized with petroleum ether, and dried to obtain 2,3,4,5-tetrachloronitrobenzene. |
