Description

Es ist ein Verfahren zur Darstellung von SiI-azanen vorgeschlagen worden, bei denen als Ausgangsprodukte Verbindungen folgenden Typs verwendet werden:A method for the preparation of SiI-azanes has been proposed, in which as starting products Connections of the following types can be used:

wobei RO sowohl primäre und sekundäre Alkoxygruppen als auch Aroxygruppen sein können, η die Werte von ι bis 3 annehmen kann und X ein Halogenatom ist. Diese Ausgangsstoffe werden in gelöster Form mit trockenem Ammoniakgas oder mit Hilfe von flüssigem Ammoniak in die entsprechenden Kieselsäureamide und anschließend durch Temperaturerhöhung in die entsprechenden Silazane übergeführt, wobei häufig schon Raumtemperatur genügt, um höhermolekulare Verbindungen zu erhalten. where RO can be primary and secondary alkoxy groups as well as aroxy groups, η can assume the values from ι to 3 and X is a halogen atom. These starting materials are converted into the corresponding silicic acid amides in dissolved form with dry ammonia gas or with the aid of liquid ammonia and then converted into the corresponding silazanes by increasing the temperature, with room temperature often being sufficient to obtain higher molecular weight compounds.

Die Erfindung betrifft eine besonders vorteilhafte Verwendungsform von nach diesem Verfahren gewonnenen Stoffen. Erfindungsgemäß werden SiI- ao azane aus mit Ammoniak zur Umsetzung gebrachten Verbindungen des TypsThe invention relates to a particularly advantageous one Form of use of substances obtained by this process. According to the invention SiI ao azanes from compounds of the type reacted with ammonia

(RO)nSiX4-,,,(RO) n SiX 4 - ,,,

wobei RO primäre und sekundäre Alkoxygruppen und Aroxygruppen sind, die Zahl η Werte von ι bis 3 annehmen kann und X ein Halogenatom ist, als korrosionsvenhütende Beimengung zu Lacken und Anstrichstoffen verwendet. Es wurde gefunden, daß eine gewisse Ammoniaktension der Silazane korrosionisverhütend wirkt, wobei im allgemeinen bereits die Luftfeuchtigkeit ischon genügt, um laufend geringe Mengen Ammoniak in Freiheit zu setzen, das seinerseits dann korrosionsverlhütend auf Metalle wirkt.where RO are primary and secondary alkoxy groups and aroxy groups, the number η can assume values from ι to 3 and X is a halogen atom, used as a corrosion-preventing admixture to paints and varnishes. It has been found that a certain amount of ammonia in the silazanes prevents corrosion, the humidity in the air generally being sufficient to continuously release small amounts of ammonia, which in turn has an anti-corrosion effect on metals.
