| Use | is effective for adult mites and mite eggs, and can control various mites of cotton, fruit trees, vegetables and other crops, it also has a good control effect on the parasitic mites of bees. The concentration used was 0.09%. for special engineering materials |
| production method | p-chlorobenzene sulfonic acid is obtained by chlorosulfonation and condensation. 1. Dry P-chlorobenzene sulfonic acid is reacted with chlorosulfonic acid at 55-60 °c with stirring for 1.5-2H. The reaction was added dropwise to cold water, and the water was analyzed at 25-35 °c. The precipitated precipitate is filtered to obtain a wet product of p-chlorobenzenesulfonyl chloride, and the wet product is heated to 55-60 ° C. For melting and allowed to stand, thereby separating p-chlorobenzenesulfonyl chloride having a content of 96% or more. 2. Condensation the molten P-chlorobenzenesulfonyl chloride is added to the condensation pan, aluminum trichloride is added, benzene is added dropwise at 60-70 °c, and the reaction is completed at 90-95 °c for 1H. The condensation solution was added to 3-4% dilute hydrochloric acid to precipitate water, filtered, washed with water until neutral, and dried to give a product with a content of 95%. Raw material consumption quota: chlorobenzene sulfonic acid (92%)1200kg/t, chlorosulfonic acid 1250kg/t, benzene 355kg/t. |
