 erst auf die zunächst entstehende, von Berthelot und Jungfleisch beschriebene Verbindung des   Alltimonpentachlorids   mit Azetylen zur Einwirkung gebracht   wurde. - Hieraus   liessen sich offenbar keine Schliisse auf den Fall ziehen, dass feste Katalysatoren angewendet werden und das Azetylen unmittelbar auf das in Azetylentetrachorid gelöste Chlor zur Einwirkung gebracht wird. Man konnte nicht voraussehen, ob unter diesen Bedingungen die Verhütung von Explosionen gesichert wäre und ob, wie bei der schon vorgeschlagenen Anwendung fester Verdünnungsmittel, eine genaue Abmessung der aufeinander einwirkenden Gasmengen entbehrlich sein würde. 



  Ausserdem wirkt bei der Benutzung des Antimonpentachlorids das zugesetzte Azetylentetrachlorid lediglich als Verdünnungsmittel, während sich im vorliegenden Fall herausgestellt hat, dass auch eine wesentliche Verstärkung der katalytischen Wirkung erzielt wird, also das Azetylentetrachlorid anscheinend auch als   Chlorüberträger   wirkt. 



   Das Verfahren wird beispielsweise in folgender Weise ausgeführt : In Azetylentetrachlorid, das sich in einem Gefäss mit Eisenspänen befindet, wird an verschiedenen Stellen Chlor und Azetylen eingeleitet. Da Azetylentetrachlorid ein gutes Lösungsmittel für Chlor, ein schlechtes für Azetylen ist, muss das Azetyleneinleitungsrohr unter dem Chloreintritt angebracht werden, so dass das aufsteigende Azetylen stets auf mit Chlor gesättigtes Azetylentetrachlorid trifft, mit dem es sich unter Mitwirkung des vorhandenen Eisens sofort zu Azetylentetrachlorid umsetzt. Auf diese Weise finden zwei zeitlich verschiedene Vorgänge statt : 1. Lösung des Chlors in Azetylentetrachlorid.

Die durch die Reaktion erzeugte Wärme wird durch Kühlung fortgenommen.

   Das gebildete Azetylentetrachlorid läuft durch ein überlaufrohr ab.

 was only brought into action on the connection of alltimony pentachloride with acetylene, described by Berthelot and Jungfleisch. Obviously, no conclusions could be drawn from this as to the case that solid catalysts are used and the acetylene is brought to act directly on the chlorine dissolved in acetylene tetrachoride. One could not foresee whether under these conditions the prevention of explosions would be ensured and whether, as with the already proposed use of solid diluents, an exact measurement of the quantities of gas acting on one another would be unnecessary.



  In addition, when using antimony pentachloride, the added acetylene tetrachloride only acts as a diluent, while in the present case it has been found that the catalytic effect is also significantly increased, i.e. the acetylene tetrachloride also apparently acts as a chlorine carrier.



   The process is carried out, for example, in the following way: In acetylene tetrachloride, which is located in a vessel with iron filings, chlorine and acetylene are introduced at various points. Since acetylene tetrachloride is a good solvent for chlorine and a bad one for acetylene, the acetylene inlet pipe must be placed under the chlorine inlet so that the ascending acetylene always meets acetylene tetrachloride saturated with chlorine, with which it is immediately converted into acetylene tetrachloride with the help of the iron present. In this way, two different processes take place over time: 1. Chlorine solution in acetylene tetrachloride.

The heat generated by the reaction is removed by cooling.

   The acetylenetetrachloride formed runs off through an overflow pipe.

PATENT-ANSPRUCH : Verfahren zur Darstellung von Azetvientetrachlorid durch Vereinigung von Azetylen und Chlor mit Hilfe nicht flüchtiger Katalysatoren, z. B. Eisen, oder unter der Einwirkung chemisch wirksamer Strahlen, dadurch gekennzeichnet, dass in eine von vornherein vorhandene Menge Azetylentetracblorid Chlor und Azetylen in Abwesenheit fester, indifferenter Verdünnungsmittel derart eingeleitet werden, dass sich das Chlor im Azetylentetrachlorid löst und sich darauf unter dem Einfluss des Katalysators oder der wirksamen Strahlen mit dem Azetylen verbindet. PATENT CLAIM: Process for the preparation of acetylene tetrachloride by combining acetylene and chlorine with the aid of non-volatile catalysts, e.g. B. iron, or under the action of chemically active rays, characterized in that chlorine and acetylene in the absence of solid, inert diluents are introduced into a pre-existing amount of acetylenetetrachloride in such a way that the chlorine dissolves in the acetylenetetrachloride and then under the influence of the Catalyst or the effective radiation combines with the acetylene.
