Properties and stability

It hydrolyzes into dichlorobenzophenone and chloroform when exposed to alkali, and can be mixed with all pesticides except strongly alkaline pesticides. Stable under acidic conditions and easily hydrolyzed in alkaline media.

Storage method


Synthesis method

Chlorine DDT and then acidically hydrolyze it to obtain dicofol.
1. Chlorination: Use dichloroethane as the solvent, add 1% azobisisobutyronitrile as the catalyst, and pass it in at 80~90℃ The chlorine gas reacted for 2 hours, and then the solvent was evaporated under reduced pressure.

2.Hydrolytic chlorination product hydrolysis reaction in p-toluenesulfonic acid 33%, sulfuric acid 33%, water 33% % mixed acidic medium, with arylsulfonic acid or lower alkylsulfonic acid as accelerator, react at 135-150°C for 5-6 hours, and then add an appropriate amount of low-boiling point solvent dichloroethane and water to form an oil-water mixture. layer, extract the oil layer, wash it with dilute alkali solution and water, and then evaporate the solvent under reduced pressure to obtain dicofol original drug.


1. Contact acaricide. Pesticide residue analysis standards.

2.Broad-spectrum acaricide , effective against adult mites, juvenile mites and eggs. It has good selectivity, does not harm natural enemies, and is safe for bees. It mainly kills harmful mites by contact, has a long residual effect and has no systemic effect. Used to control various harmful mites on cotton, fruit trees and flowers. Resistance may develop after years of use. When using, spray 20% emulsifiable concentrate 800 to 1500 times of water evenly. When using for the first time or when the temperature is high, the dilution factor can be increased.
