Abstract

LA PRESENTE INVENCION SE REFIERE A UN PROCEDIMIENTO CONTINUO PARA LA PREPARACION DE CARBONATO DE FENILMETILO CON CONVERSIONES Y PRODUCTIVIDADES PARTICULARMENTE IMPORTANTES DESDE UN PUNTO DE VISTA INDUSTRIAL Y CON UN GASTO MINIMO DE ENERGIA. EL PROCEDIMIENTO SE LLEVA A CABO EN UNA PRIMERA COLUMNA DE DESTILACION QUE CONSTA DE UNA SECCION REACTIVA INFERIOR Y UNA SECCION DE RECTIFICACION SUPERIOR Y UNA SEGUNDA COLUMNA DE RECTIFICACION, BAJO TALES CONDICIONES DE OPERACION QUE LA SECCION REACTIVA DE LA PRIMERA COLUMNA TIENE UN PERFIL TERMICO PRACTICAMENTE CONSTANTE EN LA TEMPERATURA OPTIMA DE REACCION, Y QUE CON EL USO DE LA SEGUNDA COLUMNA SE CREA UNA CIRCULACION DE CARBONATO DE DIMETILO ENTRE LA PARTE SUPERIOR E INFERIOR DE LA PRIMERA COLUMNA QUE PERMITE QUE UN EXCESO VENTAJOSO DE DIMETILCARBONATO SEA ALIMENTADO A LA PARTE INFERIOR DE LA PRIMERA COLUMNA.
