Description
Herstellung von wasserfreien Metallchloriden In der Patentschrift 502 884 ist ein Verfahren zur Herstellung von wasserfreien Chloriden, z. B. Aluminiumchlorid, aus Metalloxyden, z. B. Ton, durch Behandlung der Oxyde mit Kohlenoxyd und Chlor oder mit Phosgen in einem isolierten Reaktionsrauen unter Ausnutzung der Reaktionswärme beschrieben. Es wurde daselbst bereits erwähnt, daß sich dabei sogar höhere Temperaturen, als sie für die Reaktion zweckmäßig sind, einstellen können, so daß ein Teil des Kohlenoxyds durch lurnischen von Kohle zu dem 'lfaterial ersetzt werden kann.Production of anhydrous metal chlorides In the patent specification 502 884 a process for the production of anhydrous chlorides, for. B. aluminum chloride, from metal oxides, e.g. B. clay, described by treating the oxides with carbon monoxide and chlorine or with phosgene in an isolated reaction space utilizing the heat of reaction. It has already been mentioned there that even higher temperatures than are expedient for the reaction can be established, so that part of the carbon monoxide can be replaced by luminescent coal to form the oil.
Es hat sich nun in der weiteren Bearbeitung dieses Verfahrens gezeigt, daß bei der Arbeitsweise in größerem Maßstabe die Reaktionswärme zur Durchführung der Reaktion völlig ausreichend ist, um auch das ganze Kohlenoxyd durch Kohle ersetzen zu können. Die Kohle wird dabei vorteilhafterweise vorher mit dem Oxyd gemischt.It has now been shown in the further processing of this procedure, that when working on a larger scale, the heat of reaction to carry out the reaction is completely sufficient to replace all the carbon monoxide with charcoal to be able to. The coal is advantageously mixed with the oxide beforehand.
Beispiel Ein Schachtofen von r m innerem Durchmesser und 12 m Höhe, der außen mit einem eisernen Mantel versehen und innen mit säure- und chlorbeständigen Isoliersteinen ausgekleidet ist, wird in seinem unteren Teil mit entwässerten Formlingen aus roo Teilen K aolinton und 5o Teilen Braunkohle gefüllt und auf 6oo° aufgeheizt. Es werden sodann etwa 92 kg kaltes Chlor pro Stunde in den Ofen eingeblasen, wobei sich die Temperatur auf etwa 8oo° steigert und eine nahezu quantitative Umsetzung zu Aluminiumchlorid gemäß folgenden Gleichungen stattfindet: AI= O;,+3C+3CI_-zAlClj+3C0 bzw.Example A shaft furnace with an inner diameter of r m and a height of 12 m, the outside with an iron jacket and inside with acid- and chlorine-resistant Insulating stones is lined, is in its lower part with drained bricks filled with roo parts k aolin clay and 50 parts lignite and heated to 600 °. About 92 kg of cold chlorine per hour are then blown into the furnace, with the temperature rises to about 8oo ° and an almost quantitative conversion to aluminum chloride takes place according to the following equations: AI = O;, + 3C + 3CI_-zAlClj + 3C0 respectively.
=AL Oz,+3C+6C1_-4AlCI.,+3Cp-Die bei diesen exothermen Reaktionen auftretende Wärme ist so groß, daß dem Schachtofen nunmehr dauernd frisches, festes Ausgangsmaterial und Chlor kalt zugeführt werden können, ohne daß es noch einer besonderen Wärmezufuhr für die Aufrechterhaltung der Temperatur bedarf. Die chlorierten Formlinge, die nach der Reaktion größtenteils aus Kieselsäure und überschüssiger Kohle bestehen, können am unteren Teil des Schachtofens ebenfalls kontinuierlich ausgetragen und die Aluminiumchloriddämpfe in Kondensationskammern in fester Form niedergeschlagen werden.= AL Oz, + 3C + 6C1_-4AlCI., + 3Cp-The one that occurs in these exothermic reactions The heat is so great that the shaft furnace is now constantly supplied with fresh, solid starting material and chlorine can be supplied cold without the need for a special supply of heat required for maintaining the temperature. The chlorinated bricks that consist largely of silica and excess charcoal after the reaction, can also be continuously discharged and the aluminum chloride vapors are deposited in solid form in condensation chambers will.
Ein in der beschriebenen Weise betriebener Ofen kann ohne Unterbrechung monatelang in Betrieb behalten «erden und liefert täglich etwa 2 4.0o kg wasserfreies Aluminiumchlorid.A furnace operated in the manner described can be used without interruption keep it in operation for months and deliver around 2 40o kg of anhydrous water every day Aluminum chloride.
