PROCESS FOR THE ISOLATION OF AMINES

There is provided a method for the isolation of an amine from an aqueous solution thereof, comprising the steps of: a) contacting the aqueous solution of the amine with an adsorbent functionalized with carboxyl groups; b) removing water from the adsorbent; and c) thermally desorbing the amine. The m...

Zusammenfassung:There is provided a method for the isolation of an amine from an aqueous solution thereof, comprising the steps of: a) contacting the aqueous solution of the amine with an adsorbent functionalized with carboxyl groups; b) removing water from the adsorbent; and c) thermally desorbing the amine. The method is particularly suitable for the isolation of ethanolamine. La presente invención se relaciona con un método para el aislamiento de una amina a partir de una solución acuosa de la misma, que comprende las etapas de: a) poner en contacto la solución acuosa de la amina con un adsorbente funcionalizado con grupos carboxilo; b) remover agua del adsorbente; y c) desorber térmicamente la amina. El método es particularmente adecuado para el aislamiento de etanolamina.
