  Verfahren zur Darstellung von Zyanwasserstoff. 
 EMI1.1 
 

 <Desc/Clms Page number 2> 

 haben sich Beimengungen verhältnismässig geringer Mengen von   Frèmdgasen,   z.   B.   solcher von   1 -1500   der Reaktionsgase als vorteilhaft erwiesen. Bei Verwendung von Sauerstoff oder Luft haben sich im allgemeinen Zusätze von   2-5% bewährt.   



   Die besten Ergebnisse wurden dann erzielt, wenn durch reaktionsfördernde Fremdgase verunreinigte Reaktionsgase zur Einwirkung gebracht wurden auf Kontakte, welche durch beigemengte Verunreinigungen aktiviert waren. 



    PATENT-ANSPRÜCHE :  
1. Verfahren zur Herstellung von Zyanwasserstoff, dadurch gekennzeichnet, dass man Stickstoff und gasförmige bzw. flüchtige Kohlenstoffverbindungen gegebenenfalls unter Zusatz von Wasserstoff bei gewöhnlichem oder erhöhtem Druck über erhitzte Kontaktmassen leitet.

  Process for the preparation of hydrogen cyanide.
 EMI1.1
 

 <Desc / Clms Page number 2>

 admixtures of relatively small amounts of Frèmd gases, z. B. those of 1-1500 of the reaction gases proved to be advantageous. When using oxygen or air, additions of 2-5% have generally proven useful.



   The best results were achieved when reaction gases contaminated by reaction-promoting foreign gases were made to act on contacts which were activated by admixed impurities.



    PATENT CLAIMS:
1. A process for the preparation of hydrogen cyanide, characterized in that nitrogen and gaseous or volatile carbon compounds, optionally with the addition of hydrogen, are passed over heated contact materials at normal or elevated pressure.

Claims (1)

2. Verfahren nach Anspruch 1, gekennzeichnet durch die Verwendung von Reaktionsgasen, welche noch Beimengungen von reaktionsbegünstigenden Fremdgasen, z. B. von Sauerstoff oder Luft enthalten. 2. The method according to claim 1, characterized by the use of reaction gases which are still admixtures of reaction-promoting foreign gases, eg. B. of oxygen or air. 3. Verfahren nach den Ansprüchen 1 und 2, dadurch gekennzeichnet, dass Gemenge verschiedener Kontaktstoffe verwendet werden, vorzugsweise solcher, welche einen Kontaktstoff in überwiegender Menge enthalten. 3. The method according to claims 1 and 2, characterized in that mixtures of different contact substances are used, preferably those which contain a contact substance in a predominant amount. 4. Verfahren nach den Ansprüchen l, 2 und 3, dadurch gekennzeichnet, dass die eigentlichen Kontaktstoffe aus geeigneten Verbindungen, z. B. Karbonaten oder Nitraten, oder auch Oxyden erzeugt werden, zweckmässig durch Einwirkung der für die Durchführung des Prozesses dienenden Gase bei erhöhten Temperaturen. 4. The method according to claims l, 2 and 3, characterized in that the actual contact substances from suitable compounds, for. B. carbonates or nitrates, or oxides are generated, expediently by the action of the gases used to carry out the process at elevated temperatures. 5. Verfahren nach den Ansprüchen 1 bis 4, gekennzeichnet durch die Verwendung von Kontaktstoffen, welche aktivierend wirkende Beimengungen, wie z. B. Verbindungen der Alkalien, alkalischen Erden oder mit Erdmetalle enthalten. 5. The method according to claims 1 to 4, characterized by the use of contact substances, which activating additives such. B. contain compounds of alkalis, alkaline earths or with earth metals. 6. Verfahren nach den Ansprüchen 1 bis 5, dadurch gekennzeichnet, dass bei Verwendung von Kontakten, welche aus Metallen oder Metallegierungen bestehen, oder solche enthalten, diese einer Oxydation unterworfen werden, z. B. durch Glühen im Sauerstoff-oder Luftstrom. 6. The method according to claims 1 to 5, characterized in that when using contacts which consist of metals or metal alloys, or contain such, they are subjected to oxidation, for. B. by annealing in a stream of oxygen or air.
