Abstract

Procedimiento para la obtención de un herbicida a base de derivados de piridazona, caracterizado porque se hace reaccionar una piridazona de la fórmula **fórmula** en la cual A significa halógeno o alcoxi y Hal es halógeno, y R2 y R3 tiene los significados arriba indicados, con un alcoholato de la fórmula R-B o R1-B , en la cual R y R1 tienen los significados arriba indicados y B es sodio o potasio, en presencia de un líquido orgánico , y se mezcla la piridazona sustituida así obtenida de la fórmula**fórmula** en la cual R y R1 significan un radical alcoxi inferior, R2 es un radical difluorometilo, un átomo de flúor o cloro, o el radical X-R4 donde X=0 o S y R4 significan un radical alquilo halogenado con 1 a 3 átomos de carbono y R3 significa hidrógeno cuando R2 es difluorometilo o el radical X-R4 y R3 significa un átomo de flúor cunado -r2 es un átomo de flúor o cloro con un soporte sólido o líquido y se mezclan los componentes de mezcla íntimamente entre si
