Description

Gewinnung von technisch wertvollen Produkten aus Schwefelbarium. Nach dem Verfahren des Patents 423755 verarbeitet man Schwefelbarium in der Weise, daß man Rohschwefelbarium mit gecigneten Säuren zersetzt, z. B. in der Weise, <laß man das Rohschwefelbarium in der berechneten Menge heißen Wassers suspendiert und alsdann die berechnete Menge Salzsäure zugibt. Dabei werden Chlorbariumlaugen erhalten, die bei gewöhnlicher Temperatur an Chlorbarium gesättigt sind und aus denen das feste Salz durch Eindampfen oder sonstige geeignete Weise gewonnen werden muß.Extraction of technically valuable products from sulfur barium. According to the method of patent 423755, sulfur barium is processed in such a way that raw sulfur barium is decomposed with gecigneten acids, e.g. B. in the way, <let the raw sulfur barium suspended in the calculated amount of hot water and then the calculated amount of hydrochloric acid is added. This gives chlorobarium liquors which are saturated in chlorobarium at normal temperature and from which the solid salt must be obtained by evaporation or other suitable means.

Es wurde nun gefunden, daß man das Eindampfen der Chlorbariumlaugen teilweise oder auch ganz vermeiden kann, wenn man die Zersetzung des Schwefelbariums mit der Säure oder ähnlich wirkenden Stoffen in einer Chlorbariumlösung vornimmt.It has now been found that evaporation of the chlorobarium liquors can partially or completely avoid the decomposition of the sulfur barium with the acid or similar substances in a chlorbarium solution.

Cberraschenderweise wurde festgestellt, claß die Zersetzung des in der Chlorbariumlösung suspendierten Schwefelbariums ebenso rasch und vollständig erfolgt wie beim Arbeiten nach dem Verfahren des Hauptpatents, nach dem man das Schwefelbarium zunächst in heißem Wasser suspetfdiert und erst dann, wenn es in Lösung gegangen ist, mit der Säure zersetzt. Zweckmäßig geht man von Chlorbariumlaugen aus, die bei gewöhnlicher Temperatur gesättigt sind, um jede unnötige Verdünnung zu vermeiden. Ausführungsbeispiel. In 2,6 cbm einer Chlorbariumlauge von 31 ° Be trägt man ioookg Rolischwefelbarium tnit einem Gehalte von 70 Prozent BaS ein. Nach schwachem Anwärmen auf etwa ¢o° C läßt man iooo kg Salzsäure von i9° Be zufließen, wobei die Temperatur auf etwa 85° C steigt. Der entweichende Schwefelwasserstoff wird nach dem Verfahren des Hauptpatents auf Alkalithiosulfat verarbeitet.Surprisingly, it was found that the decomposition of the sulfur barium suspended in the chlorobarium solution takes place just as quickly and completely as when working according to the method of the main patent, according to which the sulfur barium is first suspended in hot water and only after it has dissolved with the Acid decomposes. It is expedient to start from chlorobarium liquors which are saturated at ordinary temperature in order to avoid any unnecessary dilution. Embodiment. In 2.6 cbm of a chlorobarium liquor of 31 ° Be one enters ioookg Rolischulfurbarium with a content of 70 percent BaS. After gentle warming to about ¢ o.degree. C., 100 kg of hydrochloric acid at 19.degree. C. is allowed to flow in, the temperature rising to about 85.degree. The escaping hydrogen sulfide is processed according to the procedure of the main patent on alkali thiosulfate.

Die schließlich erhaltene, bei etwa 8o° C gesättigte Chlorbariumlauge wird mittels Filterpresse oder sonstiger geeigneter Vorrichtung von dem nicht gelösten Rückstand befreit und zur Kristallisation des Chlorbariums auf gewöhnliche Temperatur abgekühlt. Dabei scheiden sich rund 66o kg Chlorbarium in Form von Kristallen ab. Von der Mutterlauge von 31 ° Be werden 2,6 cbm zum Ansetzen einer neuen Operation verwendet, während der Rest, der noch etwa 33o kg Chlorbarium enthält, zur Eindampfung gelangt oder dem Verfahren des Patents 429q.76 unterworfen werden kann, nach dem man das Chlorbarium durch Zusatz von Kochsalz zu der Lauge aussalzt. Auf diese Weise gelingt es, rund zwei Drittel des bei einer Operation entstandenen Chlorbariums in- fester Form zu gewinnen, während man den Rest entweder durch Eindampfen der Mutterlauge gewinnt oder aber durch Kochsalz aussalzt, so daß also im letzteren Falle ein Eindampfen überhaupt nicht notwendig ist.The finally obtained chlorobarium liquor, saturated at about 80 ° C is not removed by means of a filter press or other suitable device Freed residue and to crystallize the chlorobarium at ordinary temperature cooled down. Around 66o kg of chlorine barium are deposited in the form of crystals. 2.6 cbm of the mother liquor of 31 ° Be are used to schedule a new operation used, while the remainder, which still contains about 330 kg of chlorobarium, is used for evaporation arrives or can be subjected to the process of patent 429q.76, according to which the chlorine barium is salted out by adding table salt to the lye. In this way succeeds in about two thirds of the chlorine barium produced during an operation in solid form while doing the rest either by Evaporation of the mother liquor wins or it is salted out by table salt, so that in the latter case, evaporation is not necessary at all.

Die Waschlaugen des unlöslichen Rückstandes vom Rohschwefelbarium verarbeitet man zweckmäßig auf unlösliche Bariumverbindungen, z. B. auf Blank fix, desgleichen die kochsalzhaltigen Mutterlaugen von der Aussalzoperation.The washing liquors of the insoluble residue from the raw sulfur barium it is expedient to process insoluble barium compounds, e.g. B. on blank fix, likewise the saline mother liquors from the salting out operation.
