Description

Verfahren zur Herstellung von stickstoffhaltigen Kondensationsprodukten aus Acetylen und Ammoniak. Gemäß Patent 365432 werden Kondensationsprodukte aus Acetylen und Ammoniak hergestellt werden durch Überleiten eines Gemenges von Acetylen und Ammoniak über Raseneisenerz- oder Bauxit. Bei dem Verfahren tritt keine Sprengung der Kohlenstoffbindung des Acetylens unter Bildung von Cyanwasserstoff und Cyanammonium ein, sondern die Kohlenstoffbindung des Acetylens bleibt erhalten, und es werden Kondensationsprodukte gebildet, in der Hauptsache Acetonitril, ferner Pikol-'n und Homologe-neben sonstigen stickstoffhaltigen Basen und anderen Verbindungen.Process for the production of nitrogen-containing condensation products from acetylene and ammonia. According to patent 365432, condensation products are made Acetylene and ammonia are made by passing a mixture of acetylene over them and ammonia via lawn iron ore or bauxite. There is no demolition in the process the carbon bond of acetylene with the formation of hydrogen cyanide and cyanammonium one, but the carbon bond of the acetylene is retained and there will be Condensation products formed, mainly acetonitrile, also pikol-'n and Homologues - besides other nitrogenous bases and other compounds.

Es hat sich nun gezeigt, daß an Stelle von Raseneisenerz und Bauxit auch andere natürlich vorkommende Eisenerze verwandt werden können und daß dabei ebenfalls Acetonitril als Hauptprodukt auftritt, wenn diese, wie z. B. Brauneisenerz, Limonit u. dgl., aus hydratischen Eisenoxyden bestehen oder solche vorwiegend enthalten.It has now been shown that instead of lawn iron ore and bauxite other naturally occurring iron ores can be used and that acetonitrile also occurs as the main product when these, such as. B. Brown iron ore, Limonite and the like, consist of or predominantly contain hydrated iron oxides.

Diese neuen Kontaktstoffe haben gegenüber den bisher bekannten den Vorteil, daß sie mit einer größeren Festigkeit als das Raseneisenerz die Fähigkeit verbinden, in größerer @-Ienge niedrigsiedende Kondensationsprodukte, insbesondere Acetonitril, zu erzeugen, als dies weniger eisenhaltige Massen, wie Bauxit, vermögen.These new contact substances have compared to the previously known Advantage that they have a greater strength than the lawn iron ore the ability connect, in greater @ -length low-boiling condensation products, in particular Acetonitrile to produce than less ferrous masses, such as bauxite, are able to do so.

Ausführungsbeispiel. Man leitet ein Gemenge von Acetylen und Ammoniak bei 35o" über Brauneisenstein.' Durch Kühlung der Reaktionsgase wird ein Kondensat erhalten, -welches zu 77 Prozent aus unterhalb 9o'- siedenden Bestandteilen (Acetonitril mit geringen Verunreinigungen) besteht, während unter sonst ganz gleichen Bedingungen, nur mit Verwendung von Bauxit an Stelle von Brauneisenstein, ein Kondensat erhalten wurde, welches 62 Prozent unterhalb 9o° siedende Bestandteile (Acetonitril mit geringen Verunreinigungen ) enthielt.Embodiment. A mixture of acetylene and ammonia is passed over Brauneisenstein at 35o ". By cooling the reaction gases, a condensate is obtained, of which 77 percent consists of components boiling below 90 '(acetonitrile with minor impurities), while a condensate was obtained under otherwise exactly the same conditions, only with the use of bauxite instead of brown iron stone , which contained 62 percent components boiling below 90 ° (acetonitrile with minor impurities).
