Abstract

UNA SUSPENSION ACUOSA ESPESA DE ACIDO TEREFTALICO EN ACIDO ACETICO QUE SE PRODUCE MEDIANTE LA OXIDACION DE P-XILENO EN ACIDO ACETICO, ELIMINADO AGUA MEDIANTE LA EVAPORACION DE UNA CORRIENTE DE AGUA Y ACIDO ACETICO Y DEVOLVIENDO ACIDO ACETICO A LA FASE DE OXIDACION. EL ACIDO TEREFTALICO SE SEPARA DEL MEDIO DE REACCION EN UNA PRIMERA ZONA PARA DEJAR UN DEPOSITO EN UNA BANDA, EL DEPOSITO SE LAVA CON UN PRIMER MEDIO ACUOSO EN UNA SEGUNDA ZONA, SE ELIMINA DE LA BANDA EN UNA TERCERA ZONA Y SE MEZCLA CON UN SEGUNDO MEDIO ACUOSO. EL MEDIO DE REACCION SE PASA DESDE LA PRIMERA ZONA A LA FASE DE OXIDACION Y SE RECUPERA ACIDO TEREFTALICO, PREFERENTEMENTE TRAS UNA NUEVA PURIFICACION.
