Description

Verfahren zur Gewinnung von Bariumchlorid aus Schwerspat. Die Erfindung betrifft ein Verfahren zur Herstellung von Bariumchlorid aus Schwerspat (Ba SO.J mit dem wesentlichen Kennzeichen, daß Kieselsäure und Schwefelchlorid (S.. CI.) unter hoher Temperatur zur Einwirkung auf den Schwerspat gebracht werden. Eine weitere Möglichkeit zur Beschleunigung und Vervollkommnung der Reaktion besteht noch in der Mitverwendung von Kohle. Im einzelnen gestaltet sich das neue Verfahren beispielsweise so, daß ioo Teile Schwerspat mit 26 Teilen Kieselsäure vermengt und bis zu iooo° erwärmt werden; dabei wird dann etwa eine Stunde lang eine Zufuhr von Schwefelchloriddampf vorgenominen. Die Reaktion verläuft dabei etwa nach der folgenden Formel: I. Ba S04+Si02=BaSi03+SO2+O2BaSi03+2SIC12 = 2 Ba C12 + 2 S' OZ + S02 +3S- Das Reaktionserzeugnis wird mit heißem Wasser gelöst und die Lösung filtriert und verdampft. Dadurch wird das Bariumchlorid in 9o Prozent der theoretisch möglichen Menge gewonnen.Process for the production of barium chloride from barite. The invention relates to a process for the production of barium chloride from barite (Ba SO.J with the essential characteristic that silica and sulfur chloride (S .. CI.) Are brought to act on the barite at high temperature. Another possibility for acceleration and perfection In particular, the new process is designed in such a way, for example, that 100 parts of heavy spar are mixed with 26 parts of silica and heated up to 100 ° C. During this process, sulfur chloride vapor is fed in for about an hour. The reaction proceeds roughly according to the following formula: I. Ba S04 + Si02 = BaSi03 + SO2 + O2BaSi03 + 2SIC12 = 2 Ba C12 + 2 S 'OZ + S02 + 3S- The reaction product is dissolved with hot water and the solution is filtered and This means that 90 percent of the theoretically possible amount of barium chloride is obtained.

Bei der zweiten Ausführungsform des Verfahrens wird dem Gemisch von Schwerspat und Kieselsäure noch ein Anteil von 15 Teilen Kohle zugeführt. Die im übrigen gleiche Behandlung ergibt dann die Reaktion nach der folgenden Formel: II. Ba S04+Si02+C=BaSi03+SOZ+CO2BaSi03+2SpC12 =2 Ba Cl2+2Si02+SOZ+3S. Auf diesem Wege können bis 99 Prozent der theoretisch möglichen Menge an Bariumchlorid gewonnen werden.In the second embodiment of the method the mixture of barytes and silica is supplied to still a proportion of 1 5 parts of carbon. The otherwise identical treatment then results in the reaction according to the following formula: II. Ba S04 + Si02 + C = BaSi03 + SOZ + CO2BaSi03 + 2SpC12 = 2 Ba Cl2 + 2Si02 + SOZ + 3S. In this way, up to 99 percent of the theoretically possible amount of barium chloride can be obtained.

Die Kieselsäure dient in beiden Fällen als Katalysator und kann wieder verwendet werden. Katalysator bei der Reaktion gewonnene Menge an festem oder gasförmigem und gebundenem Schwefel kann für andere Zwecke nutzbar gemacht werden.The silica serves as a catalyst in both cases and can again be used. Catalyst Amount of solid or gaseous recovered in the reaction and bound sulfur can be used for other purposes.
