  Verfahren zur Gewinnung von Radiumverbindungen. 



   In dem Stammpatente Nr. 86762 wird ein Verfahren zur Gewinnung von Radiumverbindungen beschrieben, darin bestehend, dass radium-bzw. uranhaltige Gesteinsarten, Mineralien oder Materialien einer Extraktion mittels flüssiger schwefliger Säure unterworfen werden, und der Extrakt zwecks Gewinnung von Radiumverbindungen behandelt wird. 



   Versuche haben nun gezeigt, dass die Ext'aktion erleichtert wird, wenn die für die Extraktion benutzte, flüssige schweflige Säure (S02) Schwefelsäureanhydrid   (SOs)   enthält, sei es, dass die schweflige Säure infolge ihrer Herstellungsweise Schwefelsäureanhydrid enthält, sei es, dass das Schwefelsäureanhydrid der flüssigen schwefligen Säure zugesetzt wird. Durch das . Vorhandensein von   Schwefelsäureanhydrid   in der flüssigen schwefligen Säure wird die Extraktion erleichtert. 



   Der Gehalt an Schwefelsäureanhydrid wird in jedem Falle mit Rücksicht auf die Beschaffenheit der zu behandelnden Materialien bemessen. Die schwefelsäureanhydridhaltige, flüssige schweflige Säure kann zweckmässig nach bekannten Methoden getrocknet werden. 



   PATENT-ANSPRÜCHE :   I.   Verfahren zur Gewinnung von Radiumverbindungen nach dem Stammpatente Nr. 86762, dadurch gekennzeichnet, dass die für die Extraktion benutzte, flüssige schweflige
Säure Schwefelsäureanhydrid   (sous)   enthält, sei es, dass die schweflige Säure infolge ihrer
Herstellungsweise Schwefelsäureanhydrid enthält, oder sei es, dass das Schwefelsäureanhydrid der flüssigen schwefligen Säure zugesetzt wird.

  Process for the production of radium compounds.



   In the parent patent no. 86762 a process for the production of radium compounds is described, consisting in that radium or. uranium-containing rocks, minerals or materials are subjected to an extraction using liquid sulphurous acid, and the extract is treated for the purpose of obtaining radium compounds.



   Experiments have now shown that the ext'action is facilitated if the liquid sulphurous acid (SO2) used for the extraction contains sulfuric acid anhydride (SO2), be it that the sulphurous acid contains sulfuric anhydride due to the way in which it is produced, or that Sulfuric anhydride is added to the liquid sulfurous acid. By the . The presence of sulfuric anhydride in the liquid sulphurous acid will facilitate the extraction.



   The content of sulfuric anhydride is always measured with regard to the nature of the materials to be treated. The liquid sulfurous acid containing sulfuric anhydride can conveniently be dried by known methods.



   PATENT CLAIMS: I. Process for the production of radium compounds according to the parent patent no. 86762, characterized in that the liquid sulphurous used for the extraction
Acid contains sulfuric anhydride (sous), be it that the sulfurous acid as a result of it
Production method contains sulfuric anhydride, or be it that the sulfuric anhydride is added to the liquid sulfurous acid.
