Verfahren zur Darstellung von Zyanwasserstoff.

<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.
