Description
Die vorliegende Erfindung betrifft neue Phosphonigsäurediarylester sowie Diphosphonigsäure-tetraarylester, ein Verfahren zu ihrer Herstellung und deren Verwendung zur Stabilisierung von Kunststoffen.The present invention relates to new phosphonous diaryl esters and diphosphonous acid tetraaryl ester Process for their preparation and their use for Stabilization of plastics.
Es ist bekannt, daß synthetische Polymere gegen unerwünschte oxidative, thermische und photochemische Schädigung während der Herstellung, der Verarbeitung und des Gebrauchs durch Stabilisatoren oder Stabilisatorsysteme geschützt werden müssen. Solche Stabilisatoren bestehen beispielsweise aus einem phenolischen Antioxidans und einem oder mehreren Costabilisatoren, die teilweise auch die Wirkung der phenolischen Komponente synergistisch verstärken.It is known that synthetic polymers against unwanted oxidative, thermal and photochemical damage during the manufacture, processing and use by Stabilizers or stabilizer systems are protected have to. Such stabilizers consist, for example a phenolic antioxidant and one or more Costabilizers, some of which also have the effect of reinforce phenolic component synergistically.
Zu den gebräuchlichen Stabilisatoren gehören orthoalkylierte Arylphosphite und Phosphonite, wobei sich letztere vor allem durch eine weitgehende Stabilität gegen Hydrolyse auszeichnen.Common stabilizers include orthoalkylated ones Arylphosphites and Phosphonites, where the latter mainly due to extensive stability against Mark hydrolysis.
Es ist aus der EP-PS 5 447 bekannt, daß ortho-alkylierte Phenylphosphonite der Formel IIt is known from EP-PS 5 447 that ortho-alkylated Phenylphosphonites of formula I.
durch Umsetzung von Alkyl- bzw. Aryl-phosphonigsäuredichloriden mit ortho-alkylierten Phenolen in Gegenwart mindestens stöchiometrischer Mengen einer geeigneten Base zur Neutralisation der entstehenden Salzsäure hergestellt werden können. Zwar werden die in dieser Patentschrift angegebenen allgemeinen Definitionen dahingehend spezifiziert, daß innerhalb bevorzugter engerer Definitionen für die Reste R₁, R₂ und R₃ der Rest R₁ Phenyl, o-, m-, p-Tolyl, o-, m-, p-Xylyl, Mesityl, o-Cumyl, p-tert.-Butylphenyl, 2,4-Di-tert.-butyl-phenyl, 2,4,6-Tri-tert.-butylphenyl, oder 2,4-Di-tert.-octyl-phenyl, R₂ tert.-Butyl, tert.-Amyl, tert.-Octyl, tert.-Octadecyl und R₃ H, Methyl, i-Propyl, tert.-Butyl, tert.-Amyl, n-Hexyl, tert.-Octyl, tert.-Dodecyl oder n-Octadecyl, a-Methylbenzyl oder α,α-Dimethylbenzyl sein kann; von den hieraus möglichen Kombinationen werden jedoch nur zwei Ausführungsbeispiele mit R₁=Phenyl und R₂ und R₃ zugleich tert.-Butyl oder tert.-Octyl angegeben, und darüber hinaus 6 Tabellenbeispiele, von denen in dreien ebenfalls R₁ Phenyl ist und entweder R₂ tert.-Octyl und R₃ Methyl oder R₂ tert.-Butyl und R₃ Wasserstoff oder R₂ und R₃ zugleich α,α-Dimethylbenzyl. Diese 5 Verbindungen haben demnach nicht als neu zu gelten.by reacting alkyl or aryl-phosphonous dichlorides with ortho-alkylated phenols in the presence of at least stoichiometric amounts of a suitable base for neutralizing the hydrochloric acid formed. The general definitions given in this patent specification are specified to the extent that, within preferred narrower definitions for the radicals R₁, R₂ and R₃, the radical R₁ is phenyl, o-, m-, p-tolyl, o-, m-, p-xylyl, Mesityl, o-cumyl, p-tert-butylphenyl, 2,4-di-tert-butyl-phenyl, 2,4,6-tri-tert-butylphenyl, or 2,4-di-tert-octyl -phenyl, R₂ tert-butyl, tert-amyl, tert-octyl, tert-octadecyl and R₃ H, methyl, i-propyl, tert-butyl, tert-amyl, n-hexyl, tert.- Can be octyl, tert-dodecyl or n-octadecyl, a -methylbenzyl or α, α -dimethylbenzyl; of the possible combinations, however, only two examples with R₁ = phenyl and R₂ and R₃ are given tert.-butyl or tert.-octyl, as well as 6 table examples, of which R₁ is also phenyl in three and either R₂ is tert.- Octyl and R₃ methyl or R₂ tert-butyl and R₃ hydrogen or R₂ and R₃ at the same time α, α -dimethylbenzyl. These 5 connections are therefore not considered to be new.
Die Durchführung des Verfahrens der EP-PS 5 447 ist jedoch wegen der schwierigen Herstellung der als Vorprodukte benötigten Dichlorphosphane nur in begrenztem Maße möglich, was natürlich nachteilig ist, wenn eine technische Herstellung in Betracht gezogen wird. So ist Z. B. von den aromatischen Derivaten nur das Phenyl-dichlorphosaphan ein technisch verfügbares Produkt, durch das einzig Derivate der benzolphosphonigen Säure zugänglich werden, was auch verständlich werden läßt, warum von den Verbindungen, in denen R₁ einen Arylrest darstellt, gerade nur solche mit unsubstituiertem Phenyl aufgeführt sind.The implementation of the method of EP-PS 5 447 is however because of the difficult manufacture of as intermediate products required dichlorophosphanes only possible to a limited extent, which is of course disadvantageous if a technical Manufacturing is under consideration. For example, from the aromatic derivatives only the phenyl-dichlorophosaphane technically available product, through which only derivatives of benzene phosphonic acid become accessible, too makes it clear why of the connections in which R₁ represents an aryl radical, just those with unsubstituted phenyl are listed.
Zur Erfüllung der hohen Anforderungen, die in der Praxis an die Stabilität, Wirksamkeit, Schwerflüchtigkeit und das Wanderungsverhalten an Stabilisatoren für Polymere gestellt werden, ist es jedoch wünschenswert, gerade höher substituierte Derivate von Arylphosphonigsäuren zur Verfügung zu haben. Deren Zugänglichkeit nach bekannten Verfahren scheitert jedoch daran, daß die Vorprodukte bisher nicht wirtschaftlich herstellbar waren.To meet the high requirements in practice of stability, effectiveness, low volatility and that Migration behavior placed on stabilizers for polymers However, it is desirable to be just higher substituted derivatives of arylphosphonous acids are available to have. Their accessibility according to known methods however, fails because the preliminary products have not so far were economically producible.
Daher sind neue Stabilisatoren mit verbesserten Eigenschaften sowie Verfahren zu deren Herstellung, die derartige Nachteile nicht aufweisen, sehr erwünscht.Therefore new stabilizers with improved properties and processes for their preparation, such Disadvantages, very desirable.

Gegenstand der Erfindung ist auch ein Verfahren zur Herstellung von Phosphonigsäure-arylestern der Formel I, worin R¹ zusätzlich zur oben angegebenen Bedeutung auch Phenyl sowie C₁-C₁₈-Alkyl sein kann, und R² sowie R³ die obengenannte Bedeutung haben, das dadurch gekennzeichnet ist, daß man zunächst in erster Stufe ein Kohlenwasserstoff-halogenid R¹(-Hal)n, worin R¹ die obengenannte Bedeutung hat oder C₁-C₁₈-Alkyl oder Phenyl sein kann, n=1 oder 2 ist, und dessen Halogen ein Atomgewicht von mindestens 35 hat, bevorzugt jedoch Chlor oder Brom ist, unter Grignard-Bedingungen, also zweckmäßig unter inniger Durchmischung, mit mindestens molaren Mengen Magnesium zu den entsprechenden Grignard-Verbindungen R¹(MgHal)n umsetzt und diese weiter in einer zweiten Stufe mit Phosphorigsäure- bis-arylester-halogeniden der Formel II (siehe Patentanspruch 1), worin R², R³ und Hal die obengenannte Bedeutung haben, unter Bildung der Phosphonigsäure-aryl-ester I umsetzt. Die Einwirkung von Ultraschall bei der Grignard-Reaktion kann zuweilen von Vorteil sein. Dieses Verfahren ist also auch zur Herstellung der Verbindungen mit n=1 geeignet, die unter die Ausnahmeformulierung des Stoffanspruches fallen.The invention also relates to a process for the preparation of aryl phosphonous esters of the formula I, in which R¹ can also be phenyl and C₁-C₁₈-alkyl in addition to the meaning given above, and R² and R³ have the meaning given above, which is characterized in that first of all, in the first stage, a hydrocarbon halide R¹ (-Hal) n , in which R¹ has the meaning given above or can be C₁-C₁₈ alkyl or phenyl, n = 1 or 2, and the halogen of which has an atomic weight of at least 35, however, chlorine or bromine is preferred, under Grignard conditions, that is to say expediently with thorough mixing, with at least molar amounts of magnesium to give the corresponding Grignard compounds R 1 (MgHal) n and these are further treated in a second stage with bis-aryl ester halides of the formula II (see patent claim 1), in which R², R³ and Hal have the abovementioned meaning, with the formation of the phosphonous aryl ester I. Exposure to ultrasound in the Grignard reaction can sometimes be beneficial. This method is therefore also suitable for the preparation of the compounds with n = 1, which come under the exception formulation of the claim.
Die erste Stufe des erfindungsgemäßen Verfahrens, die man an sich in jeder üblichen Weise durchführen kann, wird bevorzugt in einem aprotischen, organischen Lösungsmittel wie einem Äther, z. B. Diäthyl-, Dipropyl- oder Diisopropyläther, Äthylenglykoldimethyl- oder -äthyläther, Diäthylenglykoldimethyl- oder -äthyläther, Methyl-tert.-butyläther, Dioxan oder Tetrahydrofuran durchgeführt.The first stage of the process according to the invention, which one can be performed in any conventional manner is preferred in an aprotic, organic solvent such as a Ether, e.g. B. diethyl, dipropyl or diisopropyl ether, Ethylene glycol dimethyl or ethyl ether, Diethylene glycol dimethyl or ethyl ether, methyl tert-butyl ether, Dioxane or tetrahydrofuran performed.
Da die Grignard-Verbindungen hydrolyse- und oxydationsempfindlich sind, kann es zweckmäßig sein, unter Schutzgasatmosphäre zu arbeiten. Ein solches Vorgehen ist jedoch für das Gelingen der Reaktion keineswegs zwingend. Als Schutzgas besonders geeignet sind Stickstoff und Argon. Die Reaktionstemperatur liegt im allgemeinen zwischen 20 und 125°C, bevorzugt jedoch zwischen 30 und 70°C.Since the Grignard compounds hydrolysis and are sensitive to oxidation, it may be appropriate to Protective gas atmosphere to work. Such an approach is however, in no way imperative for the success of the reaction. Nitrogen and argon are particularly suitable as protective gases. The reaction temperature is generally between 20 and 125 ° C, but preferably between 30 and 70 ° C.
Zur Herstellung der Verbindungen I wird in der zweiten Stufe die Lösung bzw. Suspension der Grignard-Verbindung zu dem Phosphorigsäure-diarylester-chlorid II, das vorteilhaft mit einem inerten, aprotischen Lösungsmittel, z. B. Hexan, Toluol, Xylol oder einem der obengenannten Äther verdünnt ist, zudosiert. Die Reaktionstemperatur liegt bei diesem Schritt im allgemeinen zwischen -30°C und +30°C, vorzugsweise aber zwischen -20°C und 0°C. Die Umsetzung verläuft in der Regel exotherm; daher kann es zweckmäßig sein, den Reaktionsverlauf durch Kühlung zu steuern. Die günstigsten Ergebnisse werden erzielt, wenn man die Reaktionspartner in den stöchiometrischen Mengen einsetzt. Es ist jedoch auch möglich, einen Reaktionspartner im Überschuß einzusetzen; im allgemeinen sind damit aber keine besonderen Vorteile verbunden. Zweckmäßig wird gerührt, bis die Umsetzung vollständig ist, und anschließend vom ausgefallenen Magnesiumhalogenid abgetrennt. Die Lösungsmittel können aus dem Filtrat in üblicher Weise, vorteilhaft destillativ, insbesondere unter vermindertem Druck, entfernt werden.In the second stage, the compounds I are prepared the solution or suspension of the Grignard compound to the Phosphorous acid diarylester chloride II, the advantageously with an inert, aprotic solvent, e.g. B. hexane, toluene, xylene or one of the above ether is diluted, added. The reaction temperature is this step generally between -30 ° C and + 30 ° C, but preferably between -20 ° C and 0 ° C. The implementation is usually exothermic; therefore it can be useful be to control the course of the reaction by cooling. The cheapest results are achieved if you have the Reactants used in the stoichiometric amounts. However, it is also possible to have a reactant in the Use excess; but in general there are none special advantages. Appropriately stirred until the implementation is complete, and then from precipitated magnesium halide separated. The Solvents can be removed from the filtrate in the usual way, advantageous by distillation, especially under reduced pressure Pressure to be removed.
Die als Ausgangsstoffe benötigten Esterchloride II können in einfacher Weise aus Phosphortrichlorid und den entsprechenden Phenolen hergestellt werden (z. B. US-PS 47 39 000). Die Reinheit der so gewonnenen Ausgangsmaterialien liegen bei etwa 85-90% (lt. ³¹P-NMR).The ester chlorides II required as starting materials can be found in simply from phosphorus trichloride and the corresponding Phenols can be produced (e.g. US Pat. No. 4,739,000). The The purity of the raw materials obtained in this way is included about 85-90% (according to 31 P NMR).
Die Produkte I können nach beliebigen Verfahren aus den Rohprodukten, bevorzugt jedoch durch Kristallisation ausgesondert werden.Products I can be obtained from the Raw products, but preferably by crystallization be discarded.
Die Synthese von Phosphonigsäureestern durch Umsetzung von metallorganischen Verbindungen mit Phosphorigsäure-diesterchloriden ist von verschiedenen Autoren beschrieben worden. Hier wird insbesondere auf die Notwendigkeit verwiesen, hochreine Phosphorigsäure-ester-chloride als Ausgangsmaterialien zu verwenden (Houben-Weyl, Methoden der Organischen Chemie, Band 12/1, 329, (1963)). Trotzdem lagen die Ausbeuten an Phosphonigsäure-diarylestern nur zwischen ca. 45 und 75%. Da bekannt ist, daß Estergruppen, die an das Phosphoratom gebunden sind, sich gegenüber metallorganischen Verbindungen grundsätzlich wie Halogenatome verhalten (Houben-Weyl, Methoden der Organischen Chemie, Band 12/1, 44 (1963) war es - auch wenn man entgegen üblicher Praxis nicht extrem reine Esterchloride II als Ausgangsmaterialien einsetzt - nicht zu erwarten, daß das vorliegende Verfahren so befriedigend und weitgehend ohne ausbeutevermindernde Konkurrenzreaktionen die Zielverbindungen liefert.The synthesis of phosphonous esters by the implementation of organometallic compounds with phosphoric acid diester chlorides has been described by various authors. Here we refer in particular to the need high purity phosphoric acid ester chloride as Use raw materials (Houben-Weyl, Methods der Organic Chemistry, Volume 12/1, 329, (1963)). Still lay the yields of phosphonous diarylesters only between approx. 45 and 75%. Since it is known that ester groups attached to the Phosphorus atom are bound to organometallic Compounds basically behave like halogen atoms (Houben-Weyl, Methods of Organic Chemistry, Volume 12/1, 44 (1963) it was - even if, contrary to normal practice, it was not extremely pure ester chlorides II as starting materials begins - not to be expected that the present proceedings so satisfactory and largely without exploitation Competitive reactions that deliver target connections.
Es ist insbesondere überraschend, daß nach dem erfindungsgemäßen Verfahren die Produkte in so hoher Ausbeute und Reinheit zugänglich sind, da nach den Angaben der Jap-OS 57-46 993 Phosphonigsäureester allgemein über Grignardreaktionen nur dann in wirtschaftlichen Ausbeuten zu erhalten sind, wenn nach der eigentlichen Grignard- Reaktion verschiedene Nachbehandlungsvorgänge unter Zusatz von Hilfsstoffen und unter Inertgasatmosphäre durchgeführt werden.It is particularly surprising that after the Process according to the invention the products in such a high yield and purity are accessible because according to the information of the Jap-OS 57-46 993 phosphonous esters in general Grignard reactions only in economic yields can be obtained if after the actual Grignard Reaction different post-treatment processes with addition of auxiliaries and carried out under an inert gas atmosphere will.
So ist es durch die vorliegende Erfindung möglich geworden, beliebig substituierte Phosphonigsäure-arylester in einfacher Weise und hoher Ausbeute und Reinheit zu erhalten.Thus, the present invention has made it possible arbitrarily substituted phosphonous acid aryl ester in simple Obtain wise and high yield and purity.
Gegenstand der Erfindung ist schließlich die Verwendung der Verbindungen der Formel I für sich oder in Kombination mit einem phenolischen Antioxidans zur Stabilisierung von Kunststoffen, vorzugsweise Polymerisationskunststoffen. Für diese Anwendung ist vielfach jedoch die Reinheit des anfallenden rohen Reaktionsprodukts (85-93% lt. ³¹P-NMR) ausreichend. Eine Isolierung in reiner Form ist dann nicht erforderlich.The invention finally relates to the use of Compounds of formula I alone or in combination with a phenolic antioxidant to stabilize Plastics, preferably polymerisation plastics. For this application, however, the purity of the resulting crude reaction product (85-93% according to 31 P-NMR) sufficient. Isolation in pure form is not then required.
In den folgenden Beispielen wurden zum Kristallisieren der erfindungsgemäß erhaltenen Verbindungen bestimmte Gemische von Lösungsmitteln verwendet. Die Angaben beziehen sich auf Volumenverhältnisse. Durch Verändern der Mischungsverhältnisse können gegebenenfalls noch Optimierungen erzielt werden. In the following examples, the Compounds obtained according to the invention certain mixtures of solvents used. The information relates on volume ratios. By changing the Mixing ratios may still apply Optimizations can be achieved.

Die erhaltene Lösung bzw. Suspension wurde anschließend innerhalb von 30-40 min bei einer Innentemperatur von -20 bis 10°C unter lebhaftem Rühren zu der Lösung von 250 mmol Phosphorigsäure- diarylester-chlorid zudosiert. Anschließend ließ man die Reaktionsmischung auf Raumtemperatur erwärmen und rührte zur Vervollständigung der Umsetzung noch 2,5 Stunden. Nach Filtration vom ausgefallenen Magnesiumsalz wurde das Lösungsmittel zunächst im Vakuum der Wasserstrahlpumpe und dann im Hochvakuum abdestilliert und der erhaltene farblose oder hellbeige Rückstand pulverisiert und im Hochvakuum getrocknet.Under a nitrogen atmosphere and excluding moisture from 250 mmol organobromine compound and 250 mmol (= 6.1 g) Mg shavings in 170 ml of tetrahydrofuran the corresponding Grignard connection established. The solution or Suspension was then added within 30-40 min an internal temperature of -20 to 10 ° C under lively Stir to the solution of 250 mmol phosphorous acid diarylester chloride metered. Then they were left Warm reaction mixture to room temperature and stirred Completion of the implementation still 2.5 hours. To Filtration of the precipitated magnesium salt was the Solvent first in the vacuum of the water jet pump and then distilled off in a high vacuum and the obtained powdered colorless or light beige residue and im High vacuum dried.
