use	2,4, 5-trichlorobenzenesulfonyl chloride is abbreviated as sulfonyl chloride, which is an important intermediate for the synthesis of acaricide trichlorosulfone.
production method	2,4, 5-trichlorobenzenesulfonyl chloride is made from trichlorobenzene. The metered chlorosulfonic acid is added to the dried chlorosulfonation kettle, stirred at 30~50 ℃, and the metered trichlorobenzene is added dropwise. After addition, the temperature is raised to 80~85 ℃ for 3h. After the reaction is completed, the temperature is reduced to about 40 ℃, and the reaction solution is slowly added dropwise into a water separation kettle with a certain amount of cold water in advance to precipitate sulfonyl chloride at 30~40 ℃. After filtration, washing and drying, the intermediate sulfonyl chloride is obtained with the content ≥ 97% and the yield ≥ 80% (calculated as 1,2, 4-trichlorobenzene). 2,4, 5-trichlorobenzenesulfonyl chloride industrial products are white porous crystals, insoluble in water, soluble in alcohol, benzene, chlorobenzene and other solvents.
