Abstract
PROCEDIMIENTO PARA LA PRODUCCION CONTINUA DE UN ACIDO CARBOXILICO AROMATICO. CONSISTE EN REALIZAR UNA REACCION DE OXIDACION EXOTERMICA EN FASE LIQUIDA, CON UN GAS QUE CONTIENE OXIGENO MOLECULAR, EN UN REACTOR DE OXIDACION; EN EL QUE SE INTRODUCE COMO CORRIENTE DE ALIMENTACION: EL PRODUCTO DE PARTIDA (P-XILENO); EL CATALIZADOR DE OXIDACION, QUE INCLUYE UNA MEZCLA DE COBALTO, MANGANESO Y BROMO; Y EL DISOLVENTE CONSTITUIDO POR UNA MEZCLA DE ACIDO ACETICO Y AGUA CON UNA RIQUEZA DEL 0,5 AL 20% EN PESO DE AGUA. ESTOS COMPONENTES PUEDEN SER INTRODUCIDOS AL REACTOR BIEN POR SEPARADO O COMO MEZCLA, EN UNA PROPORCION DE DISOLVENTE A PRODUCTO DE PARTIDA DE 1:1. LAS CONDICIONES DE OXIDACION MANTENIDAS SON: UNA TEMPERATURA DE 120J A 230JC Y UNA PRESION ABSOLUTA EN EL REACTOR DE 0 A 35 KG/CM. EL CALOR GENERADO EN EL REACTOR ES UTILIZADO PARA VAPORIZAR PARTE DEL DISOLVENTE, QUE SERA EXTRAIDO POR LA PARTE SUPERIOR DEL REACTOR; CONDENSANDOLO POSTERIORMENTE EN UN SISTEMA CONDENSADOR DE CABEZA, Y RECICLADO ALREACTOR POR UNA LINEA EXTERIOR. OBTENIENDO ACIDO TEREFTALICO COMO PRODUCTO FINAL.
