Description
Verfahren zur Herstellung von organischen Siliciumverbindungen Es ist bekannt, Siliciumhalogenide, die Wasserstoff am Silicium aufweisen, mit ungesättigten Kohlenwasserstoffen bei einer Temperatur von 6oo bis 85o° umzusetzen. Dabei bilden sich hydrolysierbare organische Siliciumhalogenide.Process for the production of organic silicon compounds Es is known to silicon halides, which have hydrogen on silicon, with unsaturated To implement hydrocarbons at a temperature of 6oo to 85o °. Form thereby hydrolyzable organic silicon halides.
Es ist weiter bekannt, aliphatische ungesättigte Kohlenwasserstoffe mit Trichlorsilan oder Monochlorsilan in Gegenwart von Polymerisationskatalysatoren bei erhöhter Temperatur und einem Mindestdruck von 2o at umzusetzen, wobei sich wachsartige, polymere organische Siliciumverbindungen bilden, die als Ersatzstoffe für die bekannten Wachse verwendet werden können.It is also known to be aliphatic unsaturated hydrocarbons with trichlorosilane or monochlorosilane in the presence of polymerization catalysts to implement at elevated temperature and a minimum pressure of 2o at, whereby Form waxy, polymeric organic silicon compounds that are used as substitutes can be used for the known waxes.
Es wurde nun gefunden, daß man leicht in Polymerisate überführbare organische Siliciumverbindungen aus halogenierten Siliciumverbindungen, die mindestens eine SiH-Gruppe enthalten, und ungesättigten aliphatischen Kohlenwasserstoffen in einfacher Weise und unter Vermeidung der Bildung von unerwünschten Nebenprodukten herstellen kann, wenn man die Umsetzung der beiden Komponenten in gasförmiger oder flüssiger Phase in Gegenwart eines katalytisch wirkenden Metalles der B. Gruppe des Periodischen Systems, insbesondere Nickel, oder eines derselben Gruppe angehörenden Metallsalzes oder Metalloxydes vornimmt.It has now been found that they can easily be converted into polymers organic silicon compounds from halogenated silicon compounds, the at least contain a SiH group, and unsaturated aliphatic hydrocarbons in in a simple manner and while avoiding the formation of undesired by-products can be produced if the implementation of the two components in gaseous or liquid phase in the presence of a catalytically active metal of the B. group of the periodic table, especially nickel, or one of the same group Metal salt or metal oxide.
Die Umsetzung kann bei normalem Druck erfolgen. Es kann aber auch ein Überdruck angewandt werden. Die Anwesenheit von Lösungsmitteln und bzw. oder bei Raumtemperatur gasförmiger Stoffe, wie Wasserstoff, Stickstoff, erweist sich öfter als zweckmäßig. Es ist zweckmäßig, den Katalysator feinverteilt auf einem Träger anzuwenden.The implementation can take place under normal pressure. But it can also an overpressure can be applied. The presence of solvents and / or Gaseous substances such as hydrogen and nitrogen at room temperature are found more often than appropriate. It is useful to finely distribute the catalyst on a Apply carrier.
Beispiel Ein gasförmiges Gemisch aus etwa gleichen Teilen Trichlorsilan und Acetylen, gegebenenfalls unter geringem Zusatz von anderen Gasen, wie z. B. Wasserstoff, -wird bei 2oo° über feinverteiltes Nickel geleitet. Es bildet sich in guter Ausbeute ein oberhalb 32° siedendes Gemisch von organischen Siliciumverbindungen, die praktisch keine SiH-Bindungen mehr enthalten. Bei der Destillation gehen Fraktionen über, die im wesentlichen folgende Siedepunkte aufweisen 25°, 32 mm, 3o bis 35°, 16 mm, 75 bis 85°, 12 mm.Example A gaseous mixture of approximately equal parts of trichlorosilane and acetylene, optionally with a small addition of other gases, such as. B. Hydrogen, - is passed over finely divided nickel at 2oo °. A mixture of organic compounds boiling above 32 ° forms in good yield Silicon compounds that practically no longer contain any SiH bonds. In the Distillation go over fractions which essentially have the following boiling points 25 °, 32 mm, 3o to 35 °, 16 mm, 75 to 85 °, 12 mm.
Die chemische Konstitution dieser Verbindungen steht nicht eindeutig fest. Sie können zu Polymerisaten verarbeitet werden, die als Rohstoffe für Harze, Lacke u. dgl. dienen können.The chemical constitution of these compounds is not clear fixed. They can be processed into polymers that are used as raw materials for resins, Paints and the like can serve.
