Description
Verfahren zur katalytischen Di-bzw. Trimerisation von 1,3-Diolefinen In den deutschen Auslegeschriften 1 050 333, 1 056 123 und im Patent 1 085 523 sind Verfahren zur Herstellung von Cyclododecatrienen-(1,5,9) neben anderen ringförmigen Kohlenwasserstoffen mit mindestens 8 Kohlenstoffatomen und mindestens zwei Doppelbindungen im Ring durch Einwirkung von Titan- bzw. Chromhalogeniden und aluminiumorganischen Verbindungen auf Isopren, Piperylen und vorzugsweise Butadien bei Temperaturen bis 1500 C, zweckmäßig in Gegenwart von Lösungsmitteln, wie aliphatischen, aromatischen oder halogenierten Kohlenwasserstoffen, beschrieben. Process for catalytic di- or. Trimerization of 1,3-Diolefins In the German Auslegeschriften 1 050 333, 1 056 123 and in the patent 1 085 523 are Process for the preparation of cyclododecatrienes (1,5,9) among other ring-shaped Hydrocarbons with at least 8 carbon atoms and at least two double bonds in the ring due to the action of titanium or chromium halides and organoaluminum Compounds on isoprene, piperylene and preferably butadiene at temperatures up to 1500 C, expediently in the presence of solvents such as aliphatic, aromatic or halogenated hydrocarbons.
Weiterhin ist es bekannt, daß Butadien gemäß dem in der deutschen Patentschrift 881 511 bzw. dem in der USA.-Patentschrift 2 686 209 beschriebenen Verfahren mit Hilfe von Katalysatoren, wie [R3P]2Ni(CO)2 bzw. (ROP)2Ni(CO)2, in Mischungen von Cyclooctadien-(1,5) und 4-Vinylcyclohexen verwandelt werden kann. Diese Katalysatoren leiten sich von dem extrem giftigen Ni(CO)4 ab und werden auch aus diesem hergestellt. Die besten Ergebnisse werden mit den Katalysatoren des genannten Typs erhalten, wenn diese durch eine Vorbehandlung mit Acetylen unter Druck aktiviert werden, aber auch dann sind immer noch lange Reaktionszeiten bis zu 100 Stunden notwendig, um tragbare Umsätze zu erzielen. It is also known that butadiene according to the German U.S. Pat. No. 881,511 or that described in U.S. Pat. No. 2,686,209 Process using catalysts such as [R3P] 2Ni (CO) 2 or (ROP) 2Ni (CO) 2, in Mixtures of cyclooctadiene (1,5) and 4-vinylcyclohexene can be converted. These catalysts are derived from the extremely toxic Ni (CO) 4 and will be made from this. The best results will be with the catalysts of the above Type obtained when activated by a pretreatment with acetylene under pressure but even then there are still long reaction times of up to 100 hours necessary to achieve sustainable sales.
Schließlich ist es bekannt, bei der Herstellung von Cyclododecatrien-(1,5,9) durch Einwirkung von Katalysatoren aus Aluminiumalkylhalogenid und Titanhalogenid auf Butadien Verbindungen mit semipolarer Doppelbindung, wie Sulfoxyde, Aminoxyde oder Nitrone, zuzusetzen. Finally, it is known that in the production of cyclododecatriene (1,5,9) by the action of catalysts made from aluminum alkyl halide and titanium halide on butadiene compounds with a semipolar double bond, such as sulfoxides, amine oxides or nitrone.
Bei der Weiterentwicklung der in den Auslegeschriften 1 050 333, 1 056 123 und im Patent 1 085 523 beschriebenen Verfahren wurde nun gefunden, daß es bei Anwendung von Katalysatoren, die durch Mischen von kohlenoxydfreien Verbindungen des Nickels oder Kobalts mit metallorganischen Verbindungen, wie Metallalkylen, Metallarylen oder Grignardverbindungen, oder mit Metallhydriden oder mit Metallhydridkomplexverbindungen und Elektronendonatoren, entstehen, gelingt, 1,3-Diolefine, wie Isopren, Piperylen oder vorzugsweise Butadien, mit hohen Ausbeuten in cyclische Verbindungen zu verwandeln. Erfindungsgemäß werden dabei vollkommen ungiftige, kohlenoxydfreie Katalysatoren eingesetzt, die keinerlei Aktivierung mit Acetylen unter Druck bedürfen und einen schnellen Reaktionsablauf garantieren. Vorzugsweise werden metallorganische Verbindungen bzw. Metallhydride der I. bis III. Gruppe des Periodischen Systems - verwendet. Die Elektronendonatoren haben hierbei die Aufgabe, die beim Umsatz der Übergangsmetallverbindungen mit den metallorganischen Verbindungen bzw. mit den Metallhydriden ohne Zusatz meist in fester Form anfallenden Katalysatoren in echter bzw. kolloidaler Lösung zu halten. In the further development of the documents in the interpretative documents 1 050 333, 1,056,123 and the method described in patent 1,085,523 has now been found that it is when using catalysts that are produced by mixing carbon-free compounds of nickel or cobalt with organometallic compounds such as metal alkyls, Metal aryls or Grignard compounds, or with metal hydrides or with metal hydride complex compounds and electron donors, 1,3-diolefins such as isoprene and piperylene are created and managed or, preferably, butadiene, to be converted into cyclic compounds in high yields. According to the invention, completely non-toxic, carbon-oxide-free catalysts are used used that do not require any activation with acetylene under pressure and one guarantee a fast response process. Organometallic compounds are preferred or metal hydrides of the I. to III. Group of the Periodic Table - used. The electron donors here have the Task that occurs in the conversion of the transition metal compounds mostly with the organometallic compounds or with the metal hydrides without additives to keep catalysts obtained in solid form in real or colloidal solution.
Während gemäß den oben zuerst genannten Verfahren ganz überwiegend Cyclododecatriene-( 1,5,9) aus Butadien gebildet werden, und zwar gemäß dem in der Auslegeschrift 1 050 333 beschriebenen Verfahren das trans,trans,cis-Cyclododecatrien-(1,5,9) und gemäß dem in der Auslegeschrift 1 056 123 beschriebenen Verfahren eine Mischung von 600/o trans,trans,trans-Cyclododecatrien-(1 5,9) und 400/o trans,trans,cis-Cyclododecatrien-(1 1,5,9), kann bei Anwendung der in bestimmter Weise zusammengesetzten neuen Katalysatoren das Cyclooctadien-(1,5) neben kleineren Mengen 4-Vinylcyclohexen zum Hauptprodukt gemacht werden. Andererseits gelingt es auch, das Cyclododecatrien-(l,5,9) zum Hauptprodukt zu machen, das aber bei Anwendung der neuen Katalysatoren ganz unerwartet als praktisch reines trans, trans,trans-Cyclododecatrien-(1,5,9) anfällt. While according to the above first-mentioned method, very predominantly Cyclododecatriene- (1,5,9) are formed from butadiene, according to the in the Auslegeschrift 1 050 333 described process the trans, trans, cis-cyclododecatriene- (1,5,9) and a mixture according to the method described in Auslegeschrift 1,056,123 of 600 / o trans, trans, trans-cyclododecatriene (1 5.9) and 400 / o trans, trans, cis-cyclododecatriene (1 1,5,9), can be done when using the new catalysts composed in a certain way the cyclooctadiene (1,5) and smaller amounts of 4-vinylcyclohexene are the main product be made. On the other hand, it is also possible to make cyclododecatriene (l, 5,9) the main product to do, but when using the new catalysts quite unexpectedly as practical pure trans, trans, trans-cyclododecatriene- (1,5,9) is obtained.
Mit besonderem Vorteil wird in Gegenwart von Lösungsmitteln gearbeitet, die durch die metallorganischen Verbindungen oder Metallhydride nicht angegriffen werden. Als solche können aliphatische, aromatische oder halogenierte Kohlenwasserstoffe angewandt werden. It is particularly advantageous to work in the presence of solvents, which are not attacked by the organometallic compounds or metal hydrides will. Aliphatic, aromatic or halogenated hydrocarbons can be used as such can be applied.
Als Elektronendonatoren werden Verbindungen eingesetzt, die sich allgemein als Lewis-Basen kennzeichnen lassen, da diese Verbindungen mit freien Elektronenpaaren an anderen Atomgruppierungen anteilig werden können. In diesem Sinne kommen verfahrensgemäß Äther, insbesondere cyclische Äther, tertiäre Amine, insbesondere cyclische tertiäre Amine, Alkylphosphine, Arylphosphine, Alkylphosphite, Arylphosphite und insbesondere Triphenylphosphin zur Anwendung. Die oben beschriebene stabilisierende Wirkung der Zusätze wird jedoch nicht allein durch diese Verbindungen mit freien Elektronenpaaren hervorgerufen, sondern erfindungsgemäß können zu diesem Zweck auch Verbindungen mit C~ C-Bindungen, wie Phenylacetylen, eingesetzt werden. Compounds are used as electron donors, which can generally be identified as Lewis bases, since these compounds with free Electron pairs on other atom groupings can be proportionate. In this In terms of the process, ethers, especially cyclic ethers, tertiary amines, in particular cyclic tertiary amines, alkyl phosphines, aryl phosphines, alkyl phosphites, Aryl phosphites and especially triphenylphosphine for use. The stabilizing one described above The effect of the additives is not only due to these compounds with free Electron pairs caused, but according to the invention can also be used for this purpose Compounds with C ~ C bonds, such as phenylacetylene, are used.
Als Elektronendonatoren kommen auch die Ausgangsdiolefine in Frage, die ihre Wirkung aber erst nach erfolgter Zusammenmischung der übrigen Katalysatorkomponenten im Reaktionsgemisch selbst entfalten.The starting diolefins can also be used as electron donors, However, their effect only after the other catalyst components have been mixed together unfold in the reaction mixture itself.
Je nach Wahl des Übergangsmetalls, des Elektronendonators und des Molverhältnisses von Übergangsmetall zu metallorganischer Komponente und Elektronendonator entstehen, wie in den Beispielen erläutert, Katalysatoren, die entweder Cyclooctadien-(1,5) neben kleineren Mengen Vinylcyclohexen oder aber trans,trans,trans-Cyclododecatrien-(1 1,5,9) neben Spuren von trans,trans,cis-Cyclododecatrien-(1,5,9) als Hauptprodukt oder aber Mischungen der genannten Verbindungen aus Butadien entstehen lassen. Depending on the choice of transition metal, electron donor and Molar ratio of transition metal to organometallic component and electron donor arise, as explained in the examples, catalysts that either cyclooctadiene (1,5) in addition to smaller amounts of vinylcyclohexene or trans, trans, trans-cyclododecatriene- (1 1,5,9) besides traces of trans, trans, cis-cyclododecatriene- (1,5,9) as the main product or mixtures of the compounds mentioned can be formed from butadiene.
Mit besonders hohen Ausbeuten werden die cyclischen Dimeren bzw. Trimeren bei Verwendung von Nickelverbindungen gebildet. Mit besonderem Vorteil werden solche Übergangsmetallverbindungen zur Herstellung der Katalysatoren verwendet, die in den eingesetzten Lösungsmitteln gut löslich sind, aber es können auch aus in den Lösungsmitteln schwer löslichen Verbindungen Katalysatoren erhalten werden, jedoch braucht in diesen Fällen die Bildung des Katalysators aus seinen Komponenten erheblich länger Zeit. Aus diesem Grund haben sich verfahrensgemäß solche Übergangsmetallverbindungen besonders bewährt, in denen die Übergangsmetallatome an organische Reste gebunden sind, wie Acetylacetonate, Acetessigesterenolate, Alkoholate, Salze schwacher organischer Säuren oder Dimethylglyoximverbindungen. The cyclic dimers or Trimers formed when using nickel compounds. With a particular advantage such transition metal compounds are used to produce the catalysts, which are readily soluble in the solvents used, but it can also consist of Catalysts are obtained in the solvent-poorly soluble compounds, however, in these cases the catalyst needs to be formed from its components considerably longer time. For this reason, according to the process, such transition metal compounds have been found especially proven, in which the transition metal atoms are bound to organic residues are like acetylacetonate, acetoacetic ester enolate, alcoholates, salts of weak organic Acids or dimethylglyoxime compounds.
Das Verfahren wird bei Normaldruck oder aber bevorzugt bei geringem Überdruck von z. B. 1 bis 20 Atm. und bei Temperaturen von 20 bis 150"C ausgeführt. Als besonders günstiger Temperaturbereich haben sich Temperaturen von 60 bis 100"C gezeigt, da einerseits bei diesen Temperaturen die Reaktion schnell genug verläuft, andererseits aber die rein thermische Dimerisation bzw. Polymerisation des Diolefins noch kaum merklich einsetzt. The process is carried out at normal pressure or, preferably, at low pressure Overpressure of z. B. 1 to 20 atm. and carried out at temperatures of 20 to 150 "C. Temperatures of 60 to 100 ° C. have proven to be a particularly favorable temperature range shown that, on the one hand, the reaction proceeds quickly enough at these temperatures, on the other hand, however, the purely thermal dimerization or polymerization of the diolefin barely noticeably begins.
Große technische Bedeutung besitzt das erfindungsgemäße Verfahren auch insofern, als es nicht notwendig ist, den Prozeß mit hochgereinigtem Butadien durchzuführen, vielmehr kann ein Rohbutadien eingesetzt werden, wie es z. B. unmittelbar im Zuge der Butan-bzw. Butendehydrierung anfällt. Die dem Butadien beigemischten Paraffine bzw. Olefine, z. B. Butan, die n-Butene und Isobutene, ragieren nicht mit dem Katalysator und können auch nach beendeter Re- aktion in die Dehydrierungsstufe zurückgeführt werden, während das Butadien praktisch quantitativ umgesetzt wird. Gemäß Beispiel 21 werden bei Anwendung eines Butadien-Buten-(l) -Gemisches (50 : 50) ebenfalls hohe Ausbeuten (etwa 96,6 0/o des umgesetzten Butadiens) an cyclischen Verbindungen erhalten. The process according to the invention is of great technical importance also insofar as it is not necessary to start the process with highly purified butadiene carry out, rather a raw butadiene can be used, as it is, for. B. immediately in the course of butane or. Butendehydrogenation occurs. The added to the butadiene Paraffins or olefins, e.g. B. butane, the n-butenes and isobutenes, do not act with the catalytic converter and can also be used after action in the dehydration stage be recycled, while the butadiene is converted practically quantitatively. According to Example 21, when using a butadiene-butene (l) mixture (50: 50) likewise high yields (about 96.6% of the converted butadiene) of cyclic Get connections.
Die verfahrensgemäß erhaltenen Verbindungen sind wertvolle Ausgangsprodukte für weitere Synthesen, so z. B. das Cyclooctadien-(1,5) zur Gewinnung von Korksäure bzw. des entsprechenden 9gliedrigen Lactams, das Cyclododecatrien-(l,5,9) zur Gewinnung der Dodecandisäure bzw. des 13gliedrigen Lactams. The compounds obtained according to the process are valuable starting materials for further syntheses, e.g. B. the cyclooctadiene (1.5) for the production of suberic acid or the corresponding 9-membered lactam, the cyclododecatriene- (l, 5.9) for the production the dodecanedioic acid or the 13-membered lactam.
Sowohl die Dicarbonsäuren als auch die Lactame sind wertvolle Monomere zur Herstellung von Polyestern bzw. Polyamiden. Aus Vinylcyclohexen gewinnt man durch Dehydrierung Styrol.Both the dicarboxylic acids and the lactams are valuable monomers for the production of polyesters or polyamides. One obtains from vinylcyclohexene by dehydration styrene.
