| toxicity | acute oral LD50>5000 mg/kg in rats. Feeding rats with a dose of 500mg/kg for 2 months, no harmful effects were found, and feeding rats with a dose of 1000mg/kg for 60 days, no abnormal phenomena of their offspring were found. |
| use | has a good effect of killing mites and young mites, with a residual period of 40 ~ 50d, and can be used to prevent cotton, citrus, apple and other plants from hatching mites, egg peak or less mites. Use content. 05%, can inhibit female mite oviposition and infertility. this product is a contact acaricide, which is used to control mites of fruit trees, cotton and vegetables. When the concentration is 0.05%, it can inhibit female mites from laying eggs and making them sterile. used to control pests such as hawthorn spider mites, apple whole melon mites, citrus whole melon mites and spider mites trichloroacilone is a contact acaricide, used to control fruit trees, cotton, and vegetables Mites. When the concentration is 0.05%, it can inhibit female mites from laying eggs and making them sterile. |
| Production method | The intermediate trichlorobenzene sulfonyl chloride is prepared by chlorosulfonation of trichlorobenzene, which is then condensed with chlorobenzene in the presence of aluminum trichloride to obtain trichloroacilone. Raw material consumption quota: trichlorobenzene 750kg/t, chlorosulfonic acid 1570kg/t, trichlorobenzenesulfonyl chloride 990kg/t, chlorobenzene 440kg/t, aluminum trichloride 500kg/t. chlorosulfonation trichlorobenzene is added dropwise to chlorosulfonic acid, the chlorosulfonic acid is excessive, the reaction temperature is 80~90 ℃, and the chlorosulfonation time is 3h. The gas discharged from the reaction is absorbed with water. The generated trichlorobenzenesulfonyl chloride is cooled and precipitated, washed with water (if necessary, a small amount of nitric acid is added to oxidize the low-sulfur compound into trichlorobenzenesulfonyl chloride), and finally it is dehydrated and dried for condensation. Condensation of trichlorobenzenesulfonyl chloride and chlorobenzene to produce trichloroacilone. The reaction is an electrophilic secondary reaction, using AlCl3 or FeCl3 as catalyst, chlorobenzene is added dropwise, the reaction temperature is 145~155 ℃, and the reaction time is 1.5~3h. The condensation product is poured into 90 ℃ hot water, stirred to precipitate trichloroacilone, washed and dried to obtain raw powder. |
