Abstract
SE DESCRIBE UN PROCEDIMIENTO PARA LA FABRICACION DE ACIDO BENZOICO. EL PROCEDIMIENTO SE BASA EN LA REACCION DE TOLUENO EN FASE LIQUIDA, OXIDACION CON 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) ENTRE 0,25:1 Y 1,5:1. EL CATALIZADOR DE TRANSFERENCIA DE FASES SE ELIGE ENTRE 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-, OH-, CH3COO- O HSO4-. EL ACIDO BENZOICO OBTENIDO SE CARACTERIZA POR SU PUREZA MUY ELEVADA Y CONVERSION ELEVADA QUE ALCANZA GENERALMENTE VALORES SUPERIORES A 95 %.
