application field

Purpose one

For the synthesis of pesticides, dyes, and pharmaceutical products

Purpose two

2,4,5-Trichloronitrobenzene is the raw material of the insecticide fluorophenuron, which is used for the synthesis of fluorophenuron intermediate 2,3,4,5-tetrachloronitrobenzene.

,

Preparation method

Method one

The preparation method is to nitrate 1,2,4-trichlorobenzene to obtain 2,4,5-trichloronitrobenzene.
The 1,2,4-trichlorobenzene was added to the reactor, and the pre-prepared mixed acid was added dropwise at room temperature. After the dropwise addition was completed, the reaction was reacted at 50 ° C for 2 hours. After the reaction was stopped, the reaction solution was poured into a large amount of ice water and allowed to stand. After filtration, 2,4,5-trichloronitrobenzene was obtained.
