1,2,4,5-Tetrazine, 3,6-bis(2-chlorophenyl)-1,4-dihydro- - References
| Use | 3, 6-bis (2-chlorophenyl)-1, 2-dihydro-1, 2,4, 5-tetrazine is an intermediate for the preparation of the acaricide tetramethazine. |
| Production method | 3, 6-bis (2-chlorophenyl)-1, 2-dihydro -1,2,4, 5-tetrazine is made by reacting bis (α, 2-dichlorobenzylidene) hydrazine and hydrazine hydrate. 85kg of toluene 260 L and bis (α,2-dichlorobenzylidene) hydrazine, 28kg of sodium carbonate and 1.5kg of phase transfer catalyst were successively put into a 500 L reactor, then the temperature was raised to 78 ℃, 25.5kg of hydrazine hydrate was added dropwise, and the temperature was kept for 1h after dropwise addition. After the reaction is over, the toluene is recovered for application; after the residue is washed with water, it is placed in a centrifuge and filtered, and the filter cake is 3, 6-bis (2-chlorophenyl)-1, 2-dihydro-1, 2,4, 5-tetrazine. Stratification of filtrate, water phase delivery wastewater treatment section, oil phase incineration treatment. |
