Abstract

LA INVENCION SE REFIERE A UN PROCESO PARA LA ELABORACION CONTINUA DE NITROAROMATOS, DONDE DESPUES DE LA REACCION SE SEPARA LA MEZCLA DE REACCION EN UNA FASE DE PRODUCTO SUPERIOR Y UNA FASE ACIDA INFERIOR. LA FASE ACIDA, QUE CONTIENE AUN SUSTANCIA ORGANICA SE LIBERA MEDIANTE EVAPORACION DE RELAJACION DE AL MENOS 5 % EN PESO DE AGUA. LOS VAPORES SE CONDENSAN EN VACIO EN CHORRO DE ROCIADO DE UN MEDIO REFRIGERANTE, GUIANDOSE UNA PARTE DEL CONDENSADO BAJO REENFRIAMIENTO EN EL CIRCUITO Y OBTENIENDOSE LOS PRODUCTOS ORGANICOS A PARTIR DE LA PARTE RESTANTE DEL CONDENSADO.
