Description
Verfahren zur Herstellung von Bariumchlorid aus Bariumsulfid unter gleichzeitiger Gewinnung von Alkalisulfhydrat. Die Darstellung von Bariumchlorid aus Bariumsulfhydratlüugen durch Umsetzung mit Alkalichlorid und unter gleichzeitiger Bildung von Alkalisulfhydrat ist bekannt. Indessen erweist sich die technische Ausführung der auf diesem Vorgang beruhenden Verfahren als umständlich und kostspielig, vor allem, weil es nicht möglich ist, die Umsetzung unmittelbar in der durch Laugen vonBariumsulfid entstehendenL ösung Vorzunehmen. Bekanntlich enthalten solche Lösungen neben Bariumsulfhydrat auch Bariumhydroxyd, das zunächst entfernt werden muß, bevor die im Vakuum konzentrierte, verbleibende Bariumsulfhydratlösung mit Alkalichloriden umgesetzt werden kann. Auch der Vorschlag, die Abscheidung des Bariumhydroxyds zu vermeiden und unmittelbar zu konzentrierten Bariumsuffhydratlösungen zu gelangen, indem das Laugen des Bariumsulfids unter Einleitung von Schwefelwasserstoff vorgenommen wird, konnte nicht befriedigen, weil dieses Verfahren die getrennte Herstellung von Schwefelwasserstoff und eine umständliche Handhabung dieses giftigen Gases erfordert.Process for the production of barium chloride from barium sulfide under simultaneous production of alkali sulfhydrate. The appearance of barium chloride from Bariumsulfhydratlüugen by reaction with alkali chloride and under simultaneous Formation of alkali sulfhydrate is known. In the meantime, the technical execution proves itself the procedures based on this process as cumbersome and costly all because it is not possible to implement directly in the through lyes solution formed by barium sulfide. It is well known that such solutions contain next to barium sulfhydrate also barium hydroxide, which must first be removed before the remaining barium sulfhydrate solution with alkali chlorides concentrated in vacuo can be implemented. Also the suggestion that the barium hydroxide be deposited avoid and reach concentrated barium sufhydrate solutions immediately, by leaching the barium sulfide with the introduction of hydrogen sulfide will not be satisfactory because this process is separate manufacture of hydrogen sulfide and cumbersome handling of this poisonous gas.
Die vorstehend erwähnte:i Übelstände vermeidet das nachstehend beschriebene, den Gegenstand dieser Erfindung bildende Verfahren auf einfachste Weise: ,Nach diesem Verfahren wird die mit wenig Wasser angeteigte Bariumsulfidschmelze zweckmäßig unter Kühlung mit so viel Salzsäure versetzt, daß die Hälfte des vorhandenen Bariums in Bariumchlorid, die andere Hälfte in Bariumsulfhydrat übergeführt wird, etwa nach der Gleichung 2 BaS -;- 2 HCI - ga CL, -7- Ba(SH)2. Durch Zusatz von Alkalichlorid zu der so erhaltenen Lösung wird das darin enthaltene 13ariumsulfhvdrat zu Bariumchlorid und Al-I:alisulfhydrat umgesetzt und weiterhin das gesamte vorhandene Bariumchlorid ausgesalzt. 'Nach Trennung vom ausgeschiedenen Bariumchlorid kann die alkalichloridhaltige Lösung von Alkalistilfhydrat ohne weiteres technisch verwendet werden.The above-mentioned: i evils avoids the following described, The method forming the subject of this invention in the simplest way: According to this The barium sulfide melt made into a paste with a little water is expediently under the process Cooling with so much hydrochloric acid added that half of the barium present in Barium chloride, the other half is converted into barium sulfhydrate, about after of equation 2 BaS -; - 2 HCI - ga CL, -7- Ba (SH) 2. By adding alkali chloride the sodium sulfate contained in the solution thus obtained becomes barium chloride and Al-I: alisulfhydrate reacted and still all of the barium chloride present salted out. 'After separation of the excreted barium chloride, the alkali chloride containing Solution of Alkalistilfhydrat can easily be used industrially.
