Abstract
Description
Die vorliegende Erfindung bezieht sich auf ein Verfahren zur Abreicherung von organometallischen Nebenprodukten in Produktgemischen, die bei der Metallocensynthese anfallen, insbesondere zur Abtrennung isomerer Metallocene, die bei der Synthese von Metallocenen entstehen.The present invention relates to a method for the depletion of organometallic by-products in product mixtures, which at Metallocene synthesis occur, especially for the separation of isomeric Metallocenes that arise during the synthesis of metallocenes.
Metallocene können, gegebenenfalls in Kombination mit einem oder mehreren Cokatalysatoren, als Katalysatoren für die Polymerisation und Copolymerisation von Olefinen verwendet werden. Insbesondere werden als Katalysatorvorstufen halogenhaltige Metallocenkomplexe eingesetzt, die sich beispielsweise durch ein Aluminoxan in einen polymerisationsaktiven kationischen Metallocenkomplex überführen lassen (EP-A-129 368).Metallocenes can, optionally in combination with one or more Cocatalysts, as catalysts for polymerization and copolymerization be used by olefins. In particular, are used as catalyst precursors halogen-containing metallocene complexes used, which are characterized, for example, by a Aluminoxane in a polymerization-active cationic metallocene complex Have transferred (EP-A-129 368).
Die Synthese von Metallocenen ist bekannt (US 4752597; US 5017714; US 5103030; EP-A-336128; EP-A-387690; EP-A-530647; EP-A-537686; EP-A-549900; H.-H. Brintzinger, D. Fischer, R. Mülhaupt, B. Rieger und R. Waymouth, Angew. Chem., 107 (1995)1255; Angew. Chem. Int. Ed. Engl., 34 (1995) 1143; M. Aulbach und F. Küber, ChiuZ, 28 (1994) 197). Dazu können Metallverbindungen, z. B. Metallalkoxide oder Metallhalogenide wie TiCl₄, ZrCl₄, HfCl₄, mit unterschiedlichsten Cyclopentadienyl-Metall-Verbindungen umgesetzt werden. Bei der Synthese von Metallocenen können erhebliche Mengen organometallischer Nebenprodukte (z. B. Isomere) entstehen, die mit dem gewünschten Metallocen vermengt sind und dessen katalytische Eigenschaften beeinträchtigen können. Beispielsweise entstehen die für die Olefinpoly merisation besonders attraktiven Bisindenyl-Metallocene in der Regel als Gemisch von racemischen und meso-Formen. Oft ist jedoch nur eine dieser isomeren Verbindungen für die stereoselektive Polymerisation von Olefinen geeignet; das andere Isomer (im Falle der verbrückten Bis-indenylmetallocene ist das zumeist die meso-Form) hat häufig eine geringere Stereoselektivität und wird abgetrennt.The synthesis of metallocenes is known (US 4752597; US 5017714; US 5103030; EP-A-336128; EP-A-387690; EP-A-530647; EP-A-537686; EP-A-549900; H.-H. Brintzinger, D. Fischer, R. Mülhaupt, B. Rieger and R. Waymouth, Angew. Chem., 107 (1995) 1255; Appl. Chem. Int. Ed. Engl., 34 (1995) 1143; M. Aulbach and F. Küber, ChiuZ, 28 (1994) 197). You can do this Metal compounds, e.g. B. metal alkoxides or metal halides such as TiCl₄, ZrCl₄, HfCl₄, implemented with a wide variety of cyclopentadienyl metal compounds will. In the synthesis of metallocenes, significant amounts can be used organometallic by-products (e.g. isomers) are formed which are associated with the desired metallocene are mixed and its catalytic properties can affect. For example, those for olefin poly arise Usually particularly attractive bisindenyl-metallocenes Mixture of racemic and meso forms. However, it is often only one of them isomeric compounds for the stereoselective polymerization of olefins suitable; the other isomer (in the case of the bridged bis-indenylmetallocenes mostly the meso form) often has a lower stereoselectivity and is separated.
Die Isolierung eines gewünschten Metallocens kann durch vollständiges Lösen des bei der Synthese anfallenden Rohproduktes mit einem geeigneten Lösungsmittel erfolgen (H.G. Alt et al., J. Organomet. Chem., 472 (1994) S. 113), wobei durch anschließende fraktionierte Kristallisation oder fraktionierte Fällung eine Abreicherung unerwünschter organometallischer Nebenprodukte (z. B. Isomere) erfolgt. Da viele Metallocene in den gebräuchlichen Lösungsmitteln nur mäßig löslich sind, erfordert das vollständige Lösen des Rohproduktes große Lösungsmittelmengen, große Filterapparate und einen hohen Zeitaufwand. Diese Vorgehensweise ist mit teilweise erheblichen Ausbeuteverlusten verbunden, wenn man höhere Reinheiten bestimmter Metallocene anstrebt. Für das vollständige Lösen werden zudem oftmals große Mengen toxischer oder umweltrelevanter Lösungsmittel eingesetzt. Außerdem sind viele Metallocene in gelöster Form empfindlich gegenüber Verunreinigungen wie Feuchtigkeitsspuren, Basen, protischen Verbindungen sowie thermischer Belastung.The isolation of a desired metallocene can be achieved by completely dissolving it of the raw product obtained in the synthesis with a suitable Solvents are used (H.G. Alt et al., J. Organomet. Chem., 472 (1994) P. 113), with subsequent fractional crystallization or fractional Precipitation depletion of unwanted organometallic by-products (e.g. isomers). Since many metallocenes are in use Solvents are only moderately soluble, requires the complete dissolution of the Large quantities of solvent, large filter apparatus and one high expenditure of time. This procedure is partly considerable Losses in yield are connected if one determines higher purities Metallocene is aiming. For complete loosening, they often become large Amounts of toxic or environmentally relevant solvents are used. Furthermore many dissolved metallocenes are sensitive to it Impurities such as traces of moisture, bases, protic compounds as well as thermal stress.
Es bestand die Aufgabe ein einfaches, schonendes und wirkungsvolles Verfahren zur Abreicherung von bei der Metallocensynthese entstehenden organometallischen Nebenprodukten zur Verfügung zu stellen.The task was simple, gentle and effective Process for the depletion of metallocene synthesis to provide organometallic by-products.
Die vorliegende Erfindung betrifft somit ein Verfahren zur Abreicherung von organometallischen Nebenprodukten in Produktgemischen, die bei der Metallocensynthese anfallen, wobei eine Mischung, enthaltend ein Metallocen und eines oder mehrere organometallische Nebenprodukte, mit einem polaren Extraktionsmittel behandelt wird. The present invention thus relates to a process for the depletion of organometallic by-products in product mixtures, which at Metallocene synthesis occur, a mixture containing a metallocene and one or more organometallic by-products, with a polar Extractant is treated.
Die in dem erfindungsgemäßen Verfahren behandelte Mischung ist vorzugsweise das bei der Metallocensynthese direkt anfallende Rohprodukt. Das Rohprodukt kann aber auch vorbehandelt sein, z. B. mit Lösungsmitteln.The mixture treated in the process according to the invention is preferably the crude product obtained directly in the metallocene synthesis. The Crude product can also be pretreated, e.g. B. with solvents.
Unter dem Begriff "organometallisches Nebenprodukt" werden alle organometallischen Verbindungen verstanden, die das gleiche Metall enthalten wie das gewünschte Metallocen; an dieses Metall ist mindestens ein kohlenstoffhaltiger Ligand, insbesondere Π-Ligand, gebunden. Ausgenommen von dieser Definition ist das gewünschte Metallocen selbst, welches angereichert beziehungsweise gereinigt werden soll.Under the term "organometallic by-product" everyone understood organometallic compounds that contain the same metal like the desired metallocene; there is at least one on this metal carbon-containing ligand, in particular Π ligand, bound. Except from this definition the desired metallocene itself is what should be enriched or cleaned.
Beispielsweise fallen unter den Begriff "organometallisches Nebenprodukt" solche Metallocene, die Isomere des gewünschten Metallocens sind, andere Metallocene, die zum gewünschten Metallocen nicht isomer sind, organometallische Verbindungen, die bei der Metallocensynthese durch unvollständige Umsetzung entstehen, oligomere und polymere Umsetzungsprodukte, sowie Verbindungen die aus dem gewünschten Metallocen oder einem der vorgenannten Nebenprodukte durch Reaktion mit Verunreinigungen, wie Wasser, Alkoholen, Aminen, basischen Verbindungen, Luft oder durch thermische Zersetzung entstehen. Der Begriff "organometallisches Nebenprodukt" wird auch dann verwendet, wenn das gewünschte Metallocen in der Mischung nur zu einem geringen Teil (etwa kleiner als 50 Gewichtsprozent) enthalten ist und eine oder mehrere der als "organometallische Nebenprodukte" bezeichneten Bestandteile mengenmäßig überwiegen.For example, the term "organometallic by-product" those metallocenes that are isomers of the desired metallocene, others Metallocenes which are not isomeric to the desired metallocene, organometallic compounds that are involved in the metallocene synthesis incomplete conversion arise, oligomeric and polymeric Reaction products, as well as compounds from the desired Metallocen or one of the aforementioned by-products by reaction with Impurities such as water, alcohols, amines, basic compounds, Air or by thermal decomposition. The term "Organometallic by-product" is used even if that desired metallocene in the mixture only to a small extent (approx less than 50 percent by weight) is included and one or more of the as "Organometallic by-products" referred to components in terms of quantity prevail.
Das in der Mischung enthaltene Metallocen enthält mindestens ein Metall zentralatom, an das mindestens zwei Π-Liganden, z. B. Cyclopentadienyl liganden gebunden sind. Bevorzugt sind chirale Metallocene. Darüber hinaus können weitere Substituenten, wie z. B. Halogen-, Alkyl-, Alkoxy-, Aryl an das Metallzentralatom gebunden sein. Das Metallzentralatom ist bevorzugt ein Element aus der III., IV., V. oder VI. Nebengruppe des Periodensystems der Elemente, insbesondere aus der IV. Nebengruppe des Periodensystems der Elemente, z. B. Zr oder Hf. Unter Cyclopentadienylligand sind unsubstituierte Cyclopentadienylreste und substituierte Cyclopentadienylreste wie Methylcyclopentadienyl, Indenyl, 2-Methylindenyl, Tetrahydroindenyl, Benzoindenyl, Fluorenyl, Benzofluorenyl, Tetrahydrofluorenyl, Octahydrofluorenylreste zu verstehen. Die Π-Liganden, z. B. Cyclopentadienylliganden können unverbrückt oder verbrückt sein, wobei einfache und mehrfache Verbrückungen - auch über Ringsysteme - möglich sind. Die Bezeichnung Metallocen umfaßt auch Verbindungen mit mehr als einem Metallocenfragment, sogenannte mehrkernige Metallocene. Diese können beliebige Substitutionsmuster und Verbrückungsvarianten aufweisen. Die einzelnen Metallocenfragmente solcher mehrkerniger Metallocene können sowohl gleichartig, als auch voneinander verschieden sein. Beispiele solcher mehrkerniger Metallocene sind z. B. beschrieben in (EP-A-632063, JP-A-O4/80214, JP-A-04/85310, EP-A-654476).The metallocene contained in the mixture contains at least one metal central atom to which at least two Π ligands, e.g. B. Cyclopentadienyl ligands are bound. Chiral metallocenes are preferred. Furthermore can further substituents, such as. B. halogen, alkyl, alkoxy, aryl to the Metal central atom. The metal central atom is preferably a Element from III., IV., V. or VI. Subgroup of the periodic table of the Elements, in particular from subgroup IV of the periodic table Elements, e.g. B. Zr or Hf. Cyclopentadienyl ligand are unsubstituted Cyclopentadienyl residues and substituted cyclopentadienyl residues such as Methylcyclopentadienyl, indenyl, 2-methylindenyl, tetrahydroindenyl, Benzoindenyl, fluorenyl, benzofluorenyl, tetrahydrofluorenyl, To understand octahydrofluorenyl residues. The Π ligands, e.g. B. Cyclopentadienyl ligands can be unbridged or bridged, where Single and multiple bridging - also via ring systems - possible are. The term metallocene also includes compounds with more than a metallocene fragment, so-called multinuclear metallocenes. these can have any substitution pattern and bridging variants. The individual metallocene fragments of such multinuclear metallocenes can be the same as well as be different from each other. Examples of such polynuclear metallocenes are e.g. B. described in (EP-A-632063, JP-A-O4 / 80214, JP-A-04/85310, EP-A-654476).
