Abstract
ESTERES TALES COMO EL ACETATO DE METIL QUE CONTENGAN IMPUREZAS DE CARBONIL INCLUYENDO ALDEHIDOS, SE PURIFICAN MEDIANTE LA ADICION A LOS ESTERES DE UN COMPUESTO AMINO QUE REACCIONA CON LOS CARBONILES PARA FORMAR DERIVADOS NITROGENACEOS SOLUBLES EN AGUA, LA SEPARACION DE LA FASE DEL ESTER ORGANICO DE LA FASE DEL DERIVADO ACUOSO, Y LA DESTILACION DE LA FASE DEL ESTER PARA SEPARAR LAS IMPUREZAS MAS PESADAS. LA FORMACION DE NITRILO A PARTIR DE LOS DERIVADOS NITROGENACEOS SE MINIMIZA MEDIANTE LA ADICION DE AGUA A LA COLUMNA DE DESTILACION O LAVANDO LOS FONDOS ACUOSOS DE LA DESTILACION CON AGUA PARA, DE ESTA FORMA, SEPARAR LOS DERIVADOS DE CUALQUIER ESTER CONTENIDO EN EL FONDO. LA FASE ORGANICA RECUERADA DEL FONDO PUEDE RECICLARSE POR DESTILACION PARA RECUPERAR EL ESTER.
