Abstract

UN PROCESO PARA LA PRODUCCION DE ACIDO ISOFTALICO DE ALTA PUREZA MEDIANTE LA OXIDACION DE M-XILENO CON UN GAS CONTENIENDO OXIGENO EN UN SOLVENTE HIDRICO DE ACIDO ACETICO EN LA PRESENCIA DE UN SISTEMA CATALIZADOR COBALTO/MANGANESO/BROMO INCLUYENDO (1) UNA ETAPA DE LLEVAR A CABO UNA REACCION DE OXIDACION EN UN REACTOR PRINCIPAL DE OXIDACION BAJO RANGOS ESPECIFICOS DE UNA CONCENTRACION DE UN CATALIZADOR, UNA TEMPERATURA DE REACCION Y UNA CONCENTRACION DE OXIGENO EN UN GAS DE DESCARGA, TAL QUE LA CONCENTRACION DE 3-CARBOXIBENZALDEHIDO LLEGA A SER DE 500 HASTA 10.000 PPM, (2) UNA ETAPA POSTERIOR DONDE SE LLEVA A CABO UNA REACCION DE OXIDACION EN UN REACTOR DE POST-OXIDACION, TAL QUE LA CONCENTRACION DE 3-CARBOXIBENZALDEHIDO LLEGA A SER DE 100 HASTA 800 PPM, SEPARACION DE ACIDO ISOFTALICO TOSCO, EVAPORACION PERMANECIENDO EL LICOR MADRE Y RECUPERANDO EL ACIDO ACETICO, Y (3) MEZCLA DEL ACIDO ISOFTALICO TOSCO CON ACIDO ACETICO PURIFICADO, AGITANDO LA MEZCLA RESULTANTE A 100 C O MAS, Y SEPARACION DELACIDO ISOFTALICO PURIFICADO.
