Abstract

PROCESO PARA PRODUCIR ISOMEROS DEL ACIDO BENCENDICARBOXILICO ALTAMENTE PURIFICADOS SIN UN PASO ADICIONAL DE PURIFICACION REDUCTORA CATALITICA, QUE COMPRENDE (A) UN PASO DE OXIDACION, EN EL QUE SE OXIDA EL ISOMERO DE XILENO CON OXIGENO MOLECULAR O GAS QUE CONTIENE OXIGENO MOLECULAR EN PRESENCIA DE UN SISTEMA CATALIZADOR COMPUESTO POR COBALTO, MANGANESO, BROMO Y AL MENOS UNO SELECCIONADO ENTRE EL NIQUEL, CROMO, CIRCONIO Y CERIO EN ACIDO CARBOXILICO ALIFATICO INFERIOR; Y (B) UN PASO DE EXTRACCION/POST-OXIDACION, EN EL QUE EL PRODUCTO DE OXIDACION SE CRISTALIZA PARA DAR UNA TORTA DE ISOMERO DE ACIDO BENCENDICARBOXILICO CRUDO, VOLVIENDOSE A DISOLVER LA TORTA POR LA ADICION A LA MISMA DE DISOLVENTE DE ACIDO CARBOXILICO ALIFATICO INFERIOR, SEGUIDO POR CALENTAMIENTO A FIN DE EXTRAER EN EL DISOLVENTE LAS IMPUREZAS QUE SE CONTIENEN EN LA MISMA, OXIDANDOSE EL LODO RESULTANTE CON DICHO SISTEMA CATALIZADOR A UNA TEMPERATURA DE 2-80 C POR DEBAJO DE LA DEL CITADO CALENTAMIENTO. SEGUN LA INVENCION, EL DISOLVENTE EMPLEADO PARA EXTRAER LAS IMPUREZAS SE RECICLA A PARTIR DE LOS PASOS SIGUIENTES DE OXIDACION.
