 EMI1.1 
 



   Katalysatoren, wie sie bei der Vereinigung von Äthylen oder   äthylenhaltigen   Gasen mit trockenem Chlorwasserstoff zum Zwecke der Darstellung von   Athylchlorid   verwendet werden (s. z. B. Ber.   57.   S.   95     ;   österr. Patente Nr.   103 496   und Nr.   103 497),   werden je nach den angewandten Reaktionsbedingungen mehr oder minder rasch dadurch unwirksam, dass sie sich mit einer Hülle von Kondensationsprodukten des Äthylens unbekannter Zusammensetzung überziehen, was in der Regel schon an einer Veränderung der Farbe oder des Glanzes äusserlich erkennbar ist. 



   Den Gegenstand der vorliegenden Erfindung bildet nun eine weitere Ausgestaltung des Verfahrens des Stammpatentes Nr.   103497, welche bezweckt.   die bei diesem Verfahren verwendeten, allmählich unwirksam gewordenen Katalysatoren in einfacher Weise zu regenerieren. Es wurde   nämlich   gefunden, dass man derartige, allmählich unwirksam gewordene bzw. erschöpfte Katalysatoren dadurch rasch und einfach regenerieren kann. wenn man sie bei erhöhter Temperatur, z. B. zwischen   100  und 800 ,   mit Chlor behandelt. 



   Beispielsweise kann ein   bis zur volligen Unwirksamkeit verbrauchter   Katalysator aus Eisenchlorid, Aluminiumchlorid oder   Aluminiumchlorid-Äthylendoppelverbindung   durch Behandlung mit Chlor bei   1000 wieder   vollständig für Zwecke der   Äthyjehloridherstellung   aufgefrischt werden.

 EMI1.1
 



   Catalysts such as those used in the combination of ethylene or ethylene-containing gases with dry hydrogen chloride for the purpose of preparing ethyl chloride (see e.g. Ber. 57, p. 95; Austrian patents No. 103 496 and No. 103 497) Depending on the reaction conditions used, they become ineffective more or less quickly because they are covered with a shell of condensation products of ethylene of unknown composition, which is usually externally recognizable by a change in color or gloss.



   The subject of the present invention now forms a further embodiment of the method of the parent patent no. 103497, which is intended. to regenerate the gradually ineffective catalysts used in this process in a simple manner. This is because it has been found that such catalysts, which have gradually become ineffective or exhausted, can thereby be regenerated quickly and easily. if you at elevated temperature, z. B. between 100 and 800, treated with chlorine.



   For example, a catalyst made of iron chloride, aluminum chloride or aluminum chloride-ethylene double compound, which has been used up to the point of being completely ineffective, can be completely refreshed again for the purpose of producing ethyl chloride by treatment with chlorine at 1000.
