Die besonderen Vorteile des erfindungsgeiräßen Verfahrens lassen sich, aus der nachstehenden. Schilderung' des Standes der Technik und der Nachteile der bekannten Verfahren erkennen: - . "The particular advantages of the method according to the invention can be seen from the following. Description of the state Recognize the technology and the disadvantages of the known methods: -. "
Gemischte Phenoxysilane waren bisher nur durch Umesterung erhältlich, z.B. durch Umsetzung von Tetraalkoxysilarjen mit Tetraaryloxysilanen in Gegenwart von sauren Katalysatoren. Die Umsetzung liefert jedoch nicht einheitliche Produkte, sondern Mischungen von Tetra.-(aikoxy-aryloxy-)sila.nen. Spezielle Produkte lassen sich, nach diesem Verfahren nur in schlechten Ausbeuten herstellen. Als Nebenprodukt treten bei der beschriebenen Umsetzung noch, größere Mengen von Kondensationsprodukten a.uf, die Siloxanbindungen enthalten, was zeigt, daß die beschriebene Methode nicht allgemein anwendbar ■ ist. Setzt man dagegen halogenierte Phenole mit Tetraalkoxysilanen in der Schmelze oder in der Lösung mit oder ohne Katalysator um, so beobachtet man, daß die Reaktion nur langsam in Gang kommt und keineswegs zu der gewünschten Endstufe führt, sondern vielmehr auf den Zwischenstufen stehen bleibt» Auch auf diese Weise erhält man nur ein schwer trennbares Produkt»Mixed phenoxysilanes were previously only available through transesterification, e.g. by reacting Tetraalkoxysilarjen with Tetraaryloxysilanen in the presence of acidic catalysts. However, the reaction does not produce uniform products, but rather mixtures of tetra .- (aikoxy-aryloxy-) sila.nen. Special products can only be produced in poor yields by this process. Step as a by-product in the implementation described, larger amounts of condensation products a.uf, which contain siloxane bonds, which shows that the method described is not generally applicable is. If, on the other hand, halogenated phenols are used with tetraalkoxysilanes in the melt or in the solution with or without a catalyst, it is observed that the reaction only gets under way slowly and in no way leads to the desired final stage leads, but rather stops at the intermediate stages » In this way, too, one only obtains a product that is difficult to separate »

Die folgenden Beispiele sollen die Erfindung erläutern:The following examples are intended to explain the invention:
In einer Rührapparatur wurden 2 Mol wasserfreies Äthanol zu einer Lösung von 1 Mol Tetrachlorsilan in 1 1 trockenem Benzol unter starkem Rühren bei "Raumtemperatur innerhalb 15 Minuten zugetropft. Die. entstehende HCl wurde mittels eines Inertgasstromes (N«) aus dem Reaktionsrauni abgeführt und zur Kontrolle in 1-normaler Natronlauge aufgefangen· Naon Beendigung der Zupane wurde ssnr Ahführung des restlichen HGl weitere 15 Minuten unter Rühren und Inertgasstrom auf 40 bis=60°0 erwärmt. Anschließend wurden 2,02 Mol 2,4,6-Trichlorphenol und 2 ml Ν,Ν-Dimethylanilin zusammen zugegeben. Das Gemisch wurde bei 40 bis 60 C =bis zur Beendigung der HGl-Entwicklung gerührt. Anschließend wurde weitere 2 Stunden am Rückfluß gekocht. Die Gesamtreaktion dauerte etwa 7 Stunden. Nach dem Entfernen des Lösungsmittels durch Abdestillation wurde das Produkt im· Vakuum destilliert. Das Bis-äthoxy-bis-(2,4,6-trichlorphenoxy)-silan destilliert bei einem Druck von 0,2 bis 0,3 nur; Hg bei 180 - 190° C. Es hat einen Schmelzpunkt von 70° C. Die Ausbeute betrug 85 σ/°. In a stirred apparatus, 2 moles of anhydrous ethanol were added dropwise to a solution of 1 mole of tetrachlorosilane in 1 l of dry benzene with vigorous stirring at room temperature over the course of 15 minutes collected in 1 normal sodium hydroxide solution · Naon termination of the zupane, the supply of the remaining HGl was heated for a further 15 minutes with stirring and a stream of inert gas to 40 to = 60 ° C. Then 2.02 mol of 2,4,6-trichlorophenol and 2 ml of Ν were added , Ν-dimethylaniline were added together. The mixture was stirred at 40 to 60 ° C. until the evolution of HGl had ceased. It was then refluxed for a further 2 hours. The overall reaction lasted about 7 hours. After the solvent had been removed by distillation, the Product distilled in vacuo. The bis-ethoxy-bis- (2,4,6-trichlorophenoxy) -silane only distills at a pressure of 0.2 to 0.3; Hg at 180-190 ° C. It ha t had a melting point of 70 ° C. The yield was 85 σ / °.

In einer 2-1-RühraOparatur wurde in einer Lösung von. 85 β (0,5 Mol) Tetrachlorsilan in,500 ml .trockenem Benzol unter sehr schnellem Rühren bei Raumtemperatur innerhalb von 10 Minuten 23 g (0>5 Mol) Äthanol wasserfrei zugetropft. Der freiwerdende Chlorwasserstoff wurde mittels eines Stickstoffstromes aus dem Reaktionsraum herausgespült, Fach Beendigung der Zugabe wurde zur Entfernung des restlichen Chlorwasserstoffs weitere 15 Minuten.unter Rühren und Inertgasstrom auf 40 bis 60° C erwärmt. Anschließend wurden 400 gf(1,5 Mol) vorgetrocknetes Pentachlorphenol, | 500 ml trockenes Benzol und 1 ml N,lf-Dimethylanilin zugesetzt. Das Gemisch wurde bei 50 bis.60° .C bis zur Beendigung der HCl-Entwicklimg gerührt. Anschließend wurde noch 3 Stunden am Rückfluß gekocht. Das erkaltete Gemisch, wurde von 32 g ausgefallenem Tetrakis-(pentachlorphenoxy)-silan (F. 280 bis 284° C) durch Filtration über eine Glasfritte befreit, auf 600 ml eingeengt und durch. Zusatz von Pentan zur Kristallisation gebracht. Die Ausbeute betrug 67 $. Das aus Benzol umkristallisierte Prodtikt hat einen Schmelzpunkt von 199 bis 202° C.In a 2-1 stirring apparatus, a solution of. 85 β (0.5 mol) tetrachlorosilane in 500 ml .trockenem benzene with very rapid stirring at room temperature within 10 minutes, 23 g (0> 5 mol) of anhydrous ethanol was added dropwise. The liberated hydrogen chloride was flushed out of the reaction space by means of a stream of nitrogen, the compartment at the end of the addition was heated to 40 to 60 ° C for a further 15 minutes with stirring and a stream of inert gas to remove the remaining hydrogen chloride. Then 400 g of f (1.5 mol) of predried pentachlorophenol, | 500 ml of dry benzene and 1 ml of N, lf-dimethylaniline were added. The mixture was stirred at 50 to 60 ° C. until the evolution of HCl had ended. The mixture was then refluxed for a further 3 hours. The cooled mixture was freed from 32 g of precipitated tetrakis (pentachlorophenoxy) silane (mp 280 to 284 ° C.) by filtration through a glass frit, concentrated to 600 ml and passed through. Bred addition of pentane to crystallize. The yield was $ 67. The product recrystallized from benzene has a melting point of 199 to 202 ° C.
