Abstract

A találmány tárgya eljárás 4-amino-5-klór-1-fenil-6-piridazinonelőállítására 4,5-diklór-1-fenil-6-piridazinon vizes ammónium-hidroxid-oldattal katalizátor jelenlétében végzett reakciójával. Akatalizátor oldódik a vizes lúgos reakcióközegben, de lényegében nemoldódik, ha a reakcióközeget a 4-amino-5-klór-1-fenil-6-piridazinoneltávolítása után megsavanyítják. A találmány szerinti eljárásbanlehetőség van a katalizátor egyszerű módon való kinyerésére ésújrahasznosítására. Ó
