Abstract

PROCEDIMIENTO PARA LA OBTENCION CONTINUA DE FORMAMIDA A PARTIR DE METILFORMIATO Y AMONIACO. SE REALIZA LA REACCION DE METILFORMIATO Y AMONIACO EN LA FASE LIQUIDA EN LA PARTE SUPERIOR DE UNA COLUMNA DE REACCION QUE TIENE EN TOTAL 15-30 PLATOS TEORICOS. SE ELIMINA EL METANOL QUE SE HA FORMADO EN ESTA REACCION JUNTO CON CANTIDADES INFERIORES DE FORMAMIDA EN FORMA DE VAPOR A LA ALTURA DEL 1<002> HASTA 5<002> PLATO DE COLUMNA. SE SEPARA LA FORMAMIDA DE ESTA MEZCLA JUNTO CON REDUCIDAS CANTIDADES DE METANOL EN UNA COLUMNA DE DESTILACION, Y SE RECICLA A LA COLUMNA DE REACCION. SE SEPARAN LAS PEQUEÑAS CANTIDADES DE METANOL CONTENIDOS EN EL PRODUCTO DE FONDO DE LA COLUMNA DE REACCION, QUE DEBE ESTAR A UNA TEMPERATURA DE 110 A 130<025>C, EN UNA SEGUNDA COLUMNA DE DESTILACION.
