Description
Das Kobalt scheidet sich in Form der Halogenide ab und kann z. B. durch Filtration, Abzentrifugieren oder Extraktion mit Wasser vom Hydroformylierungsgemisch abgetrennt werden. Das Kobalthalogenid kann als solches oder nach Überführung in Hydroxid, Carbonat leicht, z. B. zu Kobaltcarbonyl, regeneriert werden.The cobalt separates out in the form of the halides and can, for. B. by filtration, centrifugation or extraction with water from the hydroformylation mixture severed will. The cobalt halide can be used as such or after conversion into hydroxide, Carbonate light, e.g. B. to cobalt carbonyl, regenerated.
Mit sehr gutem Erfolg lassen sich auch Lösungen von Chlor, Brom oder Jod in Wasser oder organischen Lösungsmitteln zur Zersetzung der Kobaltverbindungen verwenden. Diese Ausführungsform des Verfahrens der Erfindung gestattet eine sorgfältige Dosierung der anzuwendenden Halogene und wird bevorzugt dann angewandt, wenn es sich um die Abscheidung von Kobalt aus solchen Reaktionsgemischen handelt, die empfindliche Aldehyde enthalten. Bei Verwendung von Halogenen, die in organischen Lösungsmitteln gelöst sind, erhält man wie bei der Verwendung der gasförmigen Halogene das Kobalt im allgemeinen in Form eines Halogenidniederschlages. Werden dagegen wäßrige Lösungen der Halogene eingesetzt, wie z. B. Chlorwasser, gehen die Kobalthalogenverbindungen in die wäßrige Phase über, aus der sie durch Ausfällen, z. B. mit Alkalihydroxid oder -carbonat, wiedergewonnen werden können. Solutions of chlorine, bromine or Iodine in water or organic solvents to decompose cobalt compounds use. This embodiment of the method of the invention allows for a thorough one Dosage of the halogens to be used and is preferably used when there is is the deposition of cobalt from such reaction mixtures, the sensitive Contain aldehydes. When using halogens in organic solvents are dissolved, the cobalt is obtained as with the use of the gaseous halogens generally in the form of a halide precipitate. On the other hand, they are aqueous solutions the halogens used, such. B. chlorinated water, go the cobalt halogen compounds into the aqueous phase, from which it is precipitated, e.g. B. with alkali hydroxide or carbonate, can be recovered.
Nachdem die Kobaltverbindungen abgetrennt sind, können die Abscheidung und Wiedergewinnung des Rhodiums aus den Extraktionsgemischen vorgenommen werden, die nach bekannten Verfahren erfolgt, z. B. durch einfaches Stehenlassen, durch Erhitzen, gegebenenfalls in Gegenwart von Wasser oder durch Behandeln des Reaktionsproduktes mit Wasserstoff. After the cobalt compounds have been separated, the deposition can take place and recovering the rhodium from the extraction mixtures, which is carried out by known methods, e.g. B. by simply leaving Heating, if appropriate in the presence of water or by treating the reaction product with hydrogen.
Es ist aber auch möglich, das Oxoprodukt wegen der geringen Flüchtigkeit der Rhodiumcarbonyle ohne weitere Behandlung von diesen abzudestillieren.But it is also possible to use the oxo product because of its low volatility to distill off the rhodium carbonyls from these without further treatment.
Die Menge des im Rahmen der Erfindung anzuwendenden Halogens richtet sich nach dem Kobaltgehalt des Hydroformylierungsprodruktes und muß mindestens 1 Mol Halogen, vorzugsweise 1,5 bis 5 Mol, bezogen auf 1 g-Atom Kobalt, betragen. Je nach Art der im Hydroformylierungsprodukt enthaltenen Aldehyde ist es aber auch möglich, mit noch größerem Halogenüberschuß zu arbeiten. The amount of halogen to be used in the context of the invention is directed depends on the cobalt content of the hydroformylation product and must be at least 1 Moles of halogen, preferably 1.5 to 5 moles, based on 1 g atom of cobalt. Depending on the type of aldehydes contained in the hydroformylation product, however, it is possible to work with an even larger excess of halogen.
Das erfindungsgemäße Verfahren gestattet es, Kobalt und Rhodium aus Hydroformylierungsprodukten in sehr einfacher Weise quantitativ voneinander zu trennen und nahezu verlustfrei wiederzugewinnen. The inventive method allows cobalt and rhodium from To quantitatively separate hydroformylation products from one another in a very simple manner and regain almost loss-free.
Beispiel 1 1 einer Lösung, die zu 75 Gewichtsprozent aus Benzol und zu 25 0/o aus dem Hydroformylierungsprodukt von Dicyclopentadien (in der Hauptsache Tricyclodecandialdehyd) besteht und die neben 30 mg Kobalt noch 13,8 mg Rhodium in Form ihrer Carbonyle enthält, wird intensiv mit 30 ml einer Lösung von Chlor in Wasser (4 g Chlor/l Lösung) gemischt. Example 1 1 of a solution, 75 percent by weight of benzene and to 25% from the hydroformylation product of dicyclopentadiene (mainly Tricyclodecanedialdehyde) and the 30 mg cobalt and 13.8 mg rhodium Containing in the form of their carbonyls is intensified with 30 ml of a solution of chlorine mixed in water (4 g chlorine / l solution).
Bereits nach einer Behandlungsdauer von 3 Minuten ist das Kobalt quantitativ in die wäßrige Phase übergegangen und wird aus dieser z. B. als Carbonat oder Hydroxid ausgefällt. Das vollständig in der organischen Phase zurückbleibende Rhodium scheidet sich nach mehrstündigem Stehen ab oder kann z. B. durch Behandlung mit Dampf oder mit Wasserstoff in der Hitze ausgefällt werden, während das Rhodium vollständig in der organischen Phase zurückbleibt. After a treatment time of 3 minutes it is cobalt passed quantitatively into the aqueous phase and is made from this z. B. as carbonate or hydroxide precipitated. That which remains completely in the organic phase Rhodium separates after standing for several hours or can, for. B. by treatment with steam or with hydrogen in the heat, while the rhodium remains completely in the organic phase.
