Storage method

This product should be sealed and stored in a dry place away from light. Storage and transportation according to regulations on toxic chemicals.

Synthesis method

1. Phosgene method: 2,5-dichlorobenzoyl chloride is obtained by reacting p-dichlorobenzene and phosgene, and then hydrolyzed.

2. The chloromethylation method is obtained by reacting p-dichlorobenzene with paraformaldehyde and then oxidizing it with potassium permanganate. The yield of chloromethylation of p-dichlorobenzene was 53.4%, and the yield of the third step oxidation reaction was 83%

3. The trichlorobenzene method uses 1,2,4-trichlorobenzene as raw material to prepare 2,5-dichlorobenzonitrile and then undergoes alkaline hydrolysis.

4. Benzoyl chloride method is obtained by chlorination and hydrolysis of benzoyl chloride. The chlorination temperature of benzoyl chloride is controlled between 35-45°C. The main component of the chloride obtained is 2,5-dichlorobenzoyl chloride (content 65%). Then, in the presence of concentrated sulfuric acid, it is chlorinated at 40-45°C. Hydrolyzed at 50℃.

5. Dichlorobenzene carbon tetrachloride method.

Purpose

As an intermediate in organic synthesis. It is used to synthesize the herbicides legumin and dicaoping. This pesticide has less harmful effects and is not affected by rainy weather.
