Definitions
- the present invention relates to a process for the preparation of triaryl phosphites from phosphorus trihalides and hydroxyaromatics using certain compounds containing phosphorus, nitrogen and / or sulfur as catalysts.
- triaryl phosphites have been widely used as stabilizers or costabilizers in the processing of, in particular, thermoplastics.
- the aryl groups can be substituted or unsubstituted. They are generally prepared by reacting phosphorus trihalides with hydroxyaromatics. In this reaction, high temperatures have to be used in order to achieve the most complete conversion possible, in particular when the aryl groups are substituted and the reactivity of the hydroxyl groups is hindered. However, the high temperatures and relatively long reaction times are often not sufficient to achieve complete conversion, but rather a mixture is obtained which essentially consists of mono- and diaryloxyphosphorus halides and triarylphosphites.

Description
Die vorliegende Erfindung betrifft ein Verfahren zur Herstellung von Triarylphosphiten aus Phosphortrihalogeniden und Hydroxyaromaten unter Verwendung bestimmter Phosphor, Stickstoff und/oder Schwefel enthaltender Verbindungen als Katalysatoren.The present invention relates to a process for the preparation of triaryl phosphites from phosphorus trihalides and hydroxyaromatics using certain compounds containing phosphorus, nitrogen and / or sulfur as catalysts.
Es ist bekannt, dass Triarylphosphite als Stabilisatoren bzw. Kostabilisatoren eine breite Anwendung bei der Verarbeitung von insbesondere thermoplastischen Kunststoffen gefunden haben. Die Arylgruppen können hierbei substituiert oder unsubstituiert sein. Ihre Herstellung erfolgt im allgemeinen durch die Umsetzung von Phosphortrihalogeniden mit Hydroxyaromaten. Bei dieser Reaktion müssen hohe Temperaturen angewendet werden, um einen möglichst vollständigen Umsatz zu erzeilen, insbesondere dann, wenn die Arylgruppen substituiert sind und die Reaktivität der Hydroxylgruppen behindert wird. Oft reichen jedoch die hohen Temperaturen und relativ langen Reaktionszeiten nicht aus, um eine vollständige Umsetzung zu erzielen, sondern man erhält ein Gemisch, das im wesentlichen aus Mono- und Diaryloxyphosphorhalogeniden sowie Triarylphosphiten besteht.It is known that triaryl phosphites have been widely used as stabilizers or costabilizers in the processing of, in particular, thermoplastics. The aryl groups can be substituted or unsubstituted. They are generally prepared by reacting phosphorus trihalides with hydroxyaromatics. In this reaction, high temperatures have to be used in order to achieve the most complete conversion possible, in particular when the aryl groups are substituted and the reactivity of the hydroxyl groups is hindered. However, the high temperatures and relatively long reaction times are often not sufficient to achieve complete conversion, but rather a mixture is obtained which essentially consists of mono- and diaryloxyphosphorus halides and triarylphosphites.
Es wurde daher schon vorgeschlagen, diese Reaktion in Gegenwart von Katalysatoren durchzuführen. Als mögliche Katalysatoren sind Alkali- und Erdalkalihalogenide wie z.B. LiCI, MgCI2 oder CaCl2, Metalle wie z.B. Mg oder Zn, Lewissäuren wie z.B. ZnCI2 oder AICI3 sowie als organische Verbindungen sitckstoffhaltige aromatische Heterocyclen wie Pyridin genannt, vgl. russisches Patent Nr. 488 821. Diese Lösungen sind noch nicht befriedigend und erfordern immer noch zu lange Erwärmungszeiten bei zu hohen Temperaturen.It has therefore already been proposed to carry out this reaction in the presence of catalysts. Possible catalysts include alkali and alkaline earth metal halides such as LiCl, MgCl 2 or CaCl 2 , metals such as Mg or Zn, Lewis acids such as ZnCl 2 or AICI 3 and aromatic heterocycles containing nitrogen as organic compounds such as pyridine, cf. Russian Patent No. 488 821. These solutions are not yet satisfactory and still require heating times that are too long at too high temperatures.
Die in dem russischen Patent Nr. 488 821 als geeignete Katalysatoren vorgeschlagenen quartären Phosphoniumbasen zeichnen sich zwar durch eine erhöhte Reaktivität aus, sind aber nicht ausreichend spezifisch. Besonders bei Verwendung substituierter Hydroxylaryle werden nur Gemische aus überwiegend Diarylchlor- und Triarylphosphiten erhalten.The quaternary phosphonium bases proposed as suitable catalysts in Russian Patent No. 488 821 are distinguished by an increased reactivity, but are not sufficiently specific. Especially when using substituted hydroxylaryls, only mixtures of predominantly diarylchlorophosphites and triarylphosphites are obtained.
Aufgabe vorliegender Erfindung ist es, ein Verfahren zur Herstellung von Triarylphosphiten aus Phosphortrihalogeniden und Hydroxyaromaten bereitzustellen, das durch den Einsatz reaktiver und selektiver wirkender Katalysatoren hohe Ausbeuten bei niedrigeren Temperaturen und verkürzten Reaktionszeiten ermöglicht, besonders beim Einsatz substituierter Hydroxyaromaten.The object of the present invention is to provide a process for the preparation of triaryl phosphites from phosphorus trihalides and hydroxyaromatics which, by using reactive and selective catalysts, enables high yields at lower temperatures and shorter reaction times, especially when using substituted hydroxyaromatics.

Es ist also beim erfindungsgemässen Verfahren ausgeschlossen, dass sich zwei Substituenten mit einem tertiären a-C-Atom in den 2,6-Stellungen befinden; wenn sich also in 2-Stellung eine Gruppe mit einem tertiären a-C-Atome gebunden ist, ist in 6-Stellung eine Gruppe mit einem sekundären, vorzugsweise primären C-Atom gebunden.In the case of the phenyl groups, the substituents are preferably in the 2-, 4- and / or 6-positions.

Das erfindungsgemässe Verfahren wird in hierfür bekannten Vorrichtungen durchgeführt. Im allgemeinen wird das Hydroxyaryl, gegebenenfalls zusammen mit einem Lösungsmittel vorgelegt, das Phosphortrihalogenid zugegeben und nach Zugabe des Katalysators das Reaktionsgemisch bis zur vollständigen Reaktion gerührt. Das Rühren erfolgt zur Beschleunigung der Reaktion bevorzugt unter Erwärmen.The method according to the invention is carried out in devices known for this. In general, the hydroxyaryl, optionally together with a solvent, the phosphorus trihalide is added and, after the catalyst has been added, the reaction mixture is stirred until the reaction is complete. Stirring is preferably carried out with heating to accelerate the reaction.
Es ist jedoch auch möglich den Hydroxyaromaten, gegebenenfalls ein Lösungsmittel und den Katalysator vorzulegen und das Phosphortrihalogenid langsam zuzugeben. In einigen Fällen hat es sich als vorteilhaft erwiesen, hierzu das vorgelegte Gemisch leicht zu erwärmen, z.B. bis zu 60°C, vorzugsweise bis zu 40°C. Nach Zugabe des gesamten Phosphorhaiogehides wird zur Vervollständigung gegebenenfalls unter Erwärmen bis zu 150°C nachgerührt.However, it is also possible to introduce the hydroxyaromatic compounds, if appropriate a solvent and the catalyst, and to add the phosphorus trihalide slowly. In some cases it has proven to be advantageous to heat the mixture initially, for example up to 60 ° C., preferably up to 40 ° C. After addition of the entire phosphorus shark, the mixture is optionally stirred with heating up to 150 ° C.
Der entstehende Halogenwasserstoff wird vorteilhaft während der Reaktion laufend entfernt, wobei zur vollständigen Abtrennung Vakuum verwendet werden kann. Die Isolierung des gewünschten Triarylphosphites erfolgt nach bekannten Methoden durch Destillation oder Kristallisation, gegebenenfalls nach Entfernen des Lösungsmittels.The hydrogen halide formed is advantageously removed continuously during the reaction, vacuum being able to be used for complete separation. The desired triaryl phosphite is isolated by known methods by distillation or crystallization, if appropriate after removing the solvent.
Mit dem erfindungsgemässen Verfahren werden überraschend unter schonenden Bedingungen Triarylphosphite innerhalb relativ kurzer Reaktionszeiten in hoher Reinheit und hervorragenden Ausbeuten erhalten. Besonders vorteilhaft ist bei diesem Verfahren, dass dies auch für die Herstellung von substituierten Hydroxyaromaten als Reaktanden, gilt insbesondere jenen, in denen die Reaktivität der Hydroxylgruppe durch sterische Hinderung beeinträchtigt ist.With the process according to the invention, triaryl phosphites are surprisingly obtained under mild conditions in relatively short reaction times in high purity and excellent yields. It is particularly advantageous in this process that this also applies to the production of substituted hydroxyaromatics as reactants, particularly those in which the reactivity of the hydroxyl group is impaired by steric hindrance.
Die erfindungsgemäss hergestellten Triarylphosphite sind geeignet als Stabilisatoren oder Costabilisatoren zusammen mit z.B. phenolischen Antioxidantien für die Verarbeitung von thermoplastischen Polymeren, z.B. Polyolefinen.The triaryl phosphites produced according to the invention are suitable as stabilizers or costabilizers together with e.g. phenolic antioxidants for processing thermoplastic polymers, e.g. Polyolefins.
Die nachfolgenden Beispiele erläutern die Erfindung naher.The following examples explain the invention in more detail.
In einem 250 ml-Dreihalsrundkolben mit Thermometer, Magnetrührer und angeschlossenem Gasableitungsrohr, werden 61,91 g (0,3 Mol) 2,4-Di-tert.-butylphenol in 135 ml Toluol vorgelegt, 13,73 g (0,1 Mol) Phosphortrichlorid zugesetzt und nach Zugabe von 0.003 Mol des jeweiligen Katalysators 7 h bei 2226°C gerührt. Der freigesetzte Chlorwasserstoff wird über das Gasableitungsrohr und einen kleinen angeschlossenen Blasenzähler in eine Absorptionsvorlage geleitet und mit ca. 300 ml Wasser absorbiert.61.91 g (0.3 mol) of 2,4-di-tert-butylphenol in 135 ml of toluene, 13.73 g (0.1 mol ) Added phosphorus trichloride and, after adding 0.003 mol of the respective catalyst, stirred at 2226 ° C. for 7 h. The released hydrogen chloride is passed through the gas discharge pipe and a small connected bubble counter into an absorption receiver and absorbed with approx. 300 ml of water.
Der Säuregehalt der Vorlage wird danach durch Titration mit 0,1 N-Natronlauge ermittelt.The acidity of the initial charge is then determined by titration with 0.1 N sodium hydroxide solution.
Die in der nachstehenden Tabelle 1 zusammengefassten Versuchergebnisse zeigen die überraschend hohe Wirksamkeit der Katalysatorsysteme.
Die Umsetzung mit Phosphortrichlorid und 2,4-Di-tert.-butylphenol wird gemäss Beispiel 1 durchgeführt. An Stelle von Toluol wird Chloroform als Lösungsmittel verwendet.The reaction with phosphorus trichloride and 2,4-di-tert-butylphenol is carried out according to Example 1. Instead of toluene, chloroform is used as the solvent.
Die Ergebnisse der Versuche sind in der nachstehenden Tabelle 2 zusammengefasst.
Für Vergleichszwecke wird 2.4-Ditert.-Butylphenol mit Phosphortrichlorid gemäss Beispiel 1 umgesetzt, wobei als Katalysatoren verschiedene bekannte Produkte Verwendung finden. Die Ergebnisse sind in Tabelle 3 zusammengestellt.
Die Ergebnisse der Vergleichsversuche zeigen, das durch die bislang bekannten Katalysatoren nur eine geringe Steigerung der Reaktionsgeschwindigkeit bei der Umsetzung von Phosphortrichlorid mit sterisch gehinderten Phenolen erzielt werden kann.The results of the comparative experiments show that only a slight increase in the reaction rate in the reaction of phosphorus trichloride with sterically hindered phenols can be achieved by the catalysts known to date.
In einem 500 ml-Rundkolben werden 247,6 g 2.4-Di-tert.-butylphenol (1,2 Mol), 39 g Xylol und 0,8 g Dimethylformamid (0,011 Mol) vorgelegt und auf 40°C erwärmt. Innerhalb von 15 Minuten werden 54,9 g Phosphortrichlorid (0,4 Mol) zugetropft. Das Gemisch wird noch 1 Std. bei 40-50°C gerührt, auf 130°C erhitzt und 1 Std. bei 130°C gerührt. Anschliessend wird zur Entfernung des im Reaktionsgemisch noch enthaltenen Chlorwasserstoffs 1 Std. bei 120-130°C unter vermindertem Druck (ca. 267 m bar) gerührt, wobei auch ein Teil des Lösungsmittels mitentfernt wird.247.6 g of 2,4-di-tert-butylphenol (1.2 mol), 39 g of xylene and 0.8 g of dimethylformamide (0.011 mol) are placed in a 500 ml round-bottomed flask and heated to 40.degree. 54.9 g of phosphorus trichloride (0.4 mol) are added dropwise within 15 minutes. The mixture is stirred for a further 1 hour at 40-50 ° C., heated to 130 ° C. and stirred for 1 hour at 130 ° C. The mixture is then stirred for 1 hour at 120-130 ° C. under reduced pressure (approx. 267 m bar) to remove the hydrogen chloride still present in the reaction mixture, with part of the solvent also being removed.
Zur Isolierung des Produktes wird das Reaktionsgemisch mit Isopropanol verdünnt. Das auskristallisierte Tris(2.4-di-tert.-butylphenyl)-phosphit wird abfiltriert, mit Isopropanol gewaschen und getrocknet. Es werden 221 g Produkt (85,4% Ausbeute) mit einem Schmelzpunkt von 186-187°C erhalten. Das Phosphit ist sehr rein und enthält nur noch Spuren 2.4-Di-tert.-butylphenol.To isolate the product, the reaction mixture is diluted with isopropanol. The crystallized tris (2,4-di-tert-butylphenyl) phosphite is filtered off, washed with isopropanol and dried. 221 g of product (85.4% yield) with a melting point of 186-187 ° C. are obtained. The phosphite is very pure and only contains traces of 2,4-di-tert-butylphenol.
