Abstract

PROCEDIMIENTO DE OBTENCION DE O-METALILOXIFENOL. CONSISTE EN HACER REACCIONAR CLORURO DE METALILO CON PIROCATEQUINA EN PRESENCIA DE UN AGENTE BASICO, Y EN UN MEDIO DE REACCION CONSTITUIDO POR UN DISOLVENTE ORGANICO. LA REACCION SE EFECTUA BAJO AGITACION, EN PRESENCIA DE UN CATALIZADOR ELEGIDO ENTRE DERIVADOS DE AMONIO CUATERNARIO Y DERIVADOS DE FOSFONIO, A UNA TEMPERATURA COMPRENDIDA ENTRE 50 Y 140GC, UTILIZANDO COMO AGENTE BASICO UN COMPUESTO ELEGIDO ENTRE LOS HIDROXIDOS DE METALES ALCALINOS-TERREOS, CARBONATOS DE METALES ALCALINOS Y CARBONATOS ACIDOS ALCALINOS.
