Title
(DE) VERFAHREN ZUR EXTRAKTION VON ANIONEN DER IVB BIS VIII METALLE MITTELS ALKYLSUBSTITUIERTER 1,3-DIAMINOPROPANE
(EN) METHOD FOR EXTRACTING ANIONS OF IVB TO VIII METALS USING ALKYL-SUBSTITUTED 1,3-DIAMINOPROPANES
(FR) PROCEDE PERMETTANT D'EXTRAIRE DES ANIONS DES METAUX DES GROUPES IVB A VIII AU MOYEN DE 1,3-DIAMINOPROPANES ALKYL-SUBSTITUES
Abstract
(DE)
Es wird ein Verfahren zur Extraktion von Anionen auf Basis der Metalle der V. bis VIII. Gruppe des Periodensystems aus deren wässrigen Lösung beschrieben, wobei als Extraktionsmittel Verbindungen der allgemeinen Formel (I) eingesetzt werden, wobei maximal zwei der R1, R2, R3 und R4 Wasserstoffatome und die übrigen gleiche oder verschiedene gegebenenfalls verzweigte Alkyl- oder Aminoalkylgruppen mit im Mittel mindestens 5 C-Atomen darstellen. Das erfindungsgemäße Verfahren ist insbesondere zur Extraktion von Wolfram aus Molybdän und Wolfram enthaltenden Lösungen geeignet. Ein weiter bevorzugtes Verfahren ist die extraktive Trennung von Kobalt und Nickel aus Kobalt- und Nickelionen enthaltenden wäßrigen Lösungen.
(EN)
The invention relates to a method for extracting anions based on metals of the V group to the VII group of the periodic table from the aqueous solution thereof. To this end, compounds or general formula (I) are used as an extracting agent, whereby a maximum of two of the R1, R2, R3 and R4 represent hydrogen atoms, and the remaining alkyl groups or amino alkyl groups which are optionally branched and which are the same or different represent, on average, at least 5 carbon atoms. The inventive method is especially suited for extracting tungsten from molybdenum and from solutions containing tungsten. An additionally preferred method is used for the extractive separation of cobalt and nickel from aqueous solutions containing cobalt ions and nickel ions.
(FR)
L'invention concerne un procédé qui permet d'extraire de leur solution aqueuse des anions à base de métaux des groupes V à VIII de la classification périodique, en utilisant comme agent d'extraction des composés de formule générale (I). Au maximum deux des résidus R1, R2, R3 et R4 sont des atomes d'hydrogène et les autres représentent des groupes alkyle ou aminoalkyle éventuellement ramifiés, identiques ou différents, renfermant en moyenne au moins 5 atomes de carbone. Les 1,3-diaminopropanes alkyl-substitués permettant une fixation élevée lors de l'extraction de Mo, W, V, Cr, etc. Le procédé convient notamment pour l'extraction de tungstène à partir de solutions contenant du Mo et du W. Un autre procédé avantageux est la séparation par extraction de cobalt et de nickel.
