Abstract
SE DESCRIBE UN PROCEDIMIENTO PARA LA FABRICACION DE DERIVADOS DE ACIDO BENZOICO. EL PROCEDIMIENTO SE BASA EN LA REACCION DE UN DERIVADO DE TOLUENO EN FASE LIQUIDA, OXIDACION CON UN GAS QUE CONTIENE OXIGENO, EN PRESENCIA DE UN CATALIZADOR DE TRANSFERENCIA DE FASES (A), UNA SAL DE METAL DE TRANSICION (B) Y TRAZAS DE UN DISOLVENTE POLAR, TAL COMO AGUA, ESTANDO LA RELACION MOLAR ENTRE (A) Y (B) EN EL INTERVALO DE 0,25:1 A 1,5:1. EL CATALIZADOR DE TRANSFERENCIA DE FASES SE ELIGE DE SALES DE AMONIO Y FOSFONIO CUATERNARIO, QUE TIENEN UN TOTAL DE ATOMOS DE CARBONO EN EL INTERVALO DE 17-58, SIENDO ELEGIDO EL ANION ENLAZADO ENTRE BR-, F-, CL-, CH3COO- O HSO4. LOS DERIVADOS DE ACIDO BENZOICO OBTENIDOS SE CARACTERIZAN POR SU MUY ALTA PUREZA Y ALTA CONVERSION QUE ALCANZA GENERALMENTE VALORES SUPERIORES A 95 %.
