Preparation method - The preparation method is to nitrate 1,2,4-trichlorobenzene to obtain 2,4,5-trichloronitrobenzene. Add 1,2,4-trichlorobenzene to the reactor, add pre-prepared mixed acid dropwise at room temperature, and react at 50 ° C for 2h after the dropwise addition. After stopping the reaction, pour the reaction solution into a large amount of ice water, and let it stand and filter to obtain 2,4,5-trichloronitrobenzene.
