Abstract

Reivindicación 1: Un método para producir clorofenoxi carboxilato, que comprende: someter fenoxi carboxilato a una reacción de cloración selectiva en la posición 2 y/o en la posición 4 con un agente de cloración bajo el efecto de un catalizador A y un catalizador B para obtener clorofenoxi carboxilato; en donde, el catalizador A es un ácido Lewis; y el catalizador B tiene una estructura de fórmula: R¹’-S-R²’; en donde R¹’ y R²’ se seleccionan, independientemente, del grupo que consiste en H, alquilo C₁₋₄, fenilo y fenilo sustituido, el sustituyente del fenilo sustituido es uno o más que se seleccionan del grupo que consiste en alquilo C₁₋₄, halógeno, hidroxilo, nitro, amino y ciano; y el número total de átomos de carbono de R¹’ y R²’ es de 4 - 22. Reivindicación 2: El método de acuerdo con la reivindicación 1, en donde el fenoxi carboxilato tiene una estructura representada por cualquiera de las fórmulas (1) a (4); en donde, R¹ es alquileno C₁₋₃; y R es alquilo C₁₋₁₀ o cicloalquilo C₃₋₁₀.
