2-(tert-Butyl)-4,5-dichloro-2,3-dihydropyridazin-3-one - Reference Information

Use pyridazinone (2-tert-butyl-4, 5-dichloro-3) (2H) pyridazinone is an important intermediate in the synthesis of the acaricide pyridaben.
production method pyridazinone is prepared from tert-butyl hydrazine and furochloric acid. Add 1000 of aqueous solution of tert-butylhydrazine, 500 of benzene and of furochloric acid to the L enamel reactor, stir the reaction at room temperature, add 40kg of acetic acid, and raise the temperature to 40~60 ℃, the reaction was continued with stirring for 4H. Cooling and static stratification, separation of waste water, benzene layer after washing with water separation of waste water, benzene layer under reduced pressure to remove the solvent to obtain Brown pyridazinone, the removal of benzene recycling, the wastewater was sent to the three wastes for treatment.
