3-(2,2-Dichloroethenyl)-2,2-dimethylcyclopropanecarbonyl chloride Use and Manufacturing
Its preparation method is to prepare dipermethrin acid chloride with thionyl chloride, phosphorus trichloride or phosgene. Add permethrin acid and toluene to the reaction kettle, add catalyst, and start to pass phosgene when the temperature is raised to 80℃ under stirring. The phosgene flow rate is 4m3/h, and the temperature is maintained at 80～90℃. The reaction time is about 1.5h. At the end, stop phosgene. After cooling, the excess phosgene is blown out with nitrogen, and the reaction tail gas is recovered by the tail gas absorption device, and treated with hydrochloric acid and alkali. After stopping nitrogen flow, vacuum distillation is performed, and toluene is recovered to obtain dichlorochrysanthemumyl chloride.
