Abstract
UN PROCESO CONTINUO PARA PREPARAR UN DIALQUILESTER DE UN ACIDO NAFTALENODICARBOXILICO COMPRENDE PASAR UNA MEZCLA DE REACCION EN FASE LIQUIDA QUE CONTIENE UN ALCOHOL DE PESO MOLECULAR BAJO, UN ACIDO NAFTALENODICARBOXILICO Y UN DIALQUILESTER DE UN ACIDO NAFTALENODICARBOXILICO A UNA ELEVADA TEMPERATURA A TRAVES DE ZONAS DE REACCION DISPUESTAS EN SERIE (70, 71, 72, 73) MIENTRAS SE INTRODUCE UN ACIDO NAFTALENODICARBOXILICO Y UN ALCOHOL DE PESO MOLECULAR BAJO EN UNA ZONA DE REACCION CORRIENTE ARRIBA DEL PROCESO; AGITANDO AL MENOS UNA DE LAS ZONAS DE REACCION, Y ELIMINANDO LA MEZCLA PRODUCTO LIQUIDA QUE COMPRENDE EL DIALQUILESTER DEL ACIDO NAFTALENODICARBOXILICO PRODUCIDO POR LA REACCION DEL ACIDO NAFTALENODICARBOXILICO CON EL ALCOHOL DE PESO MOLECULAR BAJO DESDE UNA ZONA DE REACCION CORRIENTE ABAJO DEL PROCESO.
