Abstract

PROCEDIMIENTO PARA LA RECUPERACION DE CAFEINA DESDE CARBONO ACTIVADO (CERTIFICADO DE ADICION DE LA PATENTE N 503.050). CONSISTE EN PONER EN CONTACTO, A UNA TEMPERATURA NO INFERIOR A 100 C, EL CARBONO ACTIVADO QUE TIENE CAFEINA ABSORBIDA CON UNA DISOLUCION ACUOSA DE ACIDO ACETICO, QUE PUEDE DESPLAZAR AL MENOS UNA PORCION DE LA CAFEINA DESDE LOS PUNTOS ACTIVOS DEL CARBONO, QUE SE DISUELVE POSTERIORMENTE EN EL DISOLVENTE; Y SEPARACION DE LA CAFEINA DE LA DISOLUCION POR DESTILACION. TIENE APLICACIONES PARA LA DESCAFEINACION DE MATERIALES VEGETALES Y DE SUS EXTRACTOS.
