| Uses | Bis (α, 2-dichlorobenzylidene) hydrazine is an important intermediate for the synthesis of the acaricide tetracarazine. |
| Production method | Bis (α, 2-dichlorobenzylidene) hydrazine is made of bis (2-chlorobenzylidene) hydrazine and chlorine gas as raw materials. 342 L, glacial acetic acid and 53 L acetic anhydride are put into a chlorination kettle, 105kg of bis (2-chlorobenzylidene) hydrazine is put into a solid feeding port, then the feeding port is closed, freezing is started, chlorine gas is introduced when the temperature of the reaction liquid drops to about 20 ℃, the reaction temperature is controlled to be 20~30 ℃, and the amount of chlorine gas is 95kg. After the chlorine gas is passed, the heat preservation is kept for 16 hours. After the heat preservation is completed, aeration is performed, and then the reaction material is put into a filter for filtration. The filtrate is sent to a distillation kettle for distillation, acetic acid is recovered for application, the residual liquid is burned, and the filter cake is washed and dried with a small amount of water. |
