Description
Verfahren zur Herstellung von wasserfreien und oxydfreien Chloriden, insbesondere von Chlormagnesium Gegenstand des Patentes 5o2 646 bildet ein Verfahren, welches dadurch gekennzeichnet ist, daß man magnesiahaltige Stoffe in Form einer Aufschlämmung in geschmolzenem Chlormagnesium oder in geschmolzenen chlormagnesiumhaltigen Salzgemischen in einem beheizten Rieselturm, einem aufsteigenden Strom des gasförmigen, chloridbildenden Mittels entgegen, herabfließen läßt.Process for the production of anhydrous and oxide-free chlorides, in particular of magnesium chloride, the subject of patent 5o2 646 is a process, which is characterized in that one magnesia-containing substances in the form of a Slurry in molten chloromagnesium or in molten chloromagnesium containing Salt mixtures in a heated trickle tower, an ascending stream of the gaseous, Chloride-forming agent against, lets flow down.
In weiterer Ausarbeitung der Erfindung hat sich gezeigt, daß man dieses Verfahren mit besonderem Vorteil mit den Verfahren nach Patent 450 979 verbinden kann. Dies geschieht in der Weise, daß man die nach diesen Verfahren hergestellten stark porösen, verkokten Formlinge in einem geeigneten Behälter, wie beispielsweise einem Schacht, auf eine elektrisch beheizte Rieselschicht - wie sie im Patent 5o2 646 beschrieben ist - aufbringt und mit dem am unteren Ende des Rieselturmes eintretenden, die ganze Rieselschicht durchstreichenden Chlor unmittelbar über der Rieselschicht zur Umsetzung bringt. Die stark exotherme Wirkung der Reaktion steigert die Temperatur des Reaktionsgutes und beschleunigt damit die Umsetzung wesentlich. Hierbei läßt man im Gegensatz zum Verfahren des Patentes 450 979 die Temperatur über den Scbmelzpunkt des Chlormagnesiums steigen, so daß ein hochprozentiges, nur wenige Prozente Magnesia und etwas überschüssige Kohle (neben etwaigen anderen Chloriden) enthaltendes Chlormagnesium zum Schmelzen kommt. Dieses geschmolzene Magnesiumchlorid wird sofort von der darunterliegenden, etwa 8oo ° heißen Rieselschicht aufgenommen und fließt über dieselbe, dem aufsteigenden Strom konzentrierten Chlorgases entgegen, in großer Oberflächenentwicklung herab. Auf diese Weise werden die letzten Mengen im Magnesiumchlorid noch suspendierter Magnesia leicht umgesetzt, und man erhält in einem Arbeitsgang aus Magnesia oder Mg0 bildenden Stoffen ein sehr reines Chlormagnesium in wasserfreier, geschmolzener Form.In a further elaboration of the invention it has been shown that this method can be combined with the method according to Patent 450,979 with particular advantage. This is done in such a way that the highly porous, coked moldings produced by this process are applied in a suitable container, such as a shaft, to an electrically heated trickle layer - as described in patent 502,646 - and with the one at the lower end The chlorine entering the trickle tower and sweeping through the entire trickle layer brings about implementation immediately above the trickle layer. The strongly exothermic effect of the reaction increases the temperature of the reaction mixture and thus accelerates the reaction considerably. In contrast to the process of patent 450 979, the temperature is allowed to rise above the melting point of magnesium chloride so that a high percentage of magnesium chloride containing only a few percent magnesia and a little excess carbon (in addition to any other chlorides) melts. This molten magnesium chloride is immediately absorbed by the underlying trickle layer, which has a temperature of about 8oo °, and flows down over the same, against the rising stream of concentrated chlorine gas, with a large surface development. In this way, the last amounts of magnesia still suspended in the magnesium chloride are easily converted, and a very pure chloromagnesium in anhydrous, molten form is obtained in one operation from magnesia or MgO-forming substances.
Es ist nötig, die Temperatur bei der Chlorierung unterhalb der Schmelztemperatur des zu erzeugenden Chlorides zu halten. Im Gegensatz dazu kann man sich bei dem vorliegenden Verfahren die Vorteile der rascheren Chlorierung bei höherer Temperatur zunutze machen, weil die unterhalb der Chlorierungszone angeordnete, beheizte Rieselschicht das schmelzende *) Von dem Patentsucher sind als die Erfinder angegeben worden: Dr. Robert Suchr, Dr. Karl Staib und Dr. Wilhelm Moschel in Bitterfeld, Chlorid sofort abfließen läßt, bevor es mit unfertigem, stark oxydhaltigem Material zu einer reaktionsunfähigen Masse verbacken kann. Das in der Hauptreaktionszone nicht verbrauchte Chlor wird von den durch die Abgase erhitzten darüberliegenden Formlingen vollständig aufgenommen.It is necessary to keep the temperature during the chlorination below the melting temperature of the chloride to be produced. In contrast, you can in the present method the benefits of rapid chlorination at higher temperatures make advantage because the arranged below the chlorination zone, heated Rieselschicht the melting *) From the patent seekers have been given as the inventor Dr. Robert Suchr, Dr. Karl Staib and Dr. Wilhelm Moschel in Bitterfeld, allows chloride to run off immediately before it can bake to an unreactive mass with unfinished, high-oxide material. The chlorine not consumed in the main reaction zone is completely absorbed by the moldings above, which are heated by the exhaust gases.
